Chapter Text

Killua knew Gon was going to steal his coffee before Gon’s hand even reached for the mug.

It was not a guess. It was a pattern. One of the smaller, stupider laws of their apartment, right underneath Gon, leaving muddy boots by the door no matter how many times Killua threatened to throw them off the balcony, and Killua pretending he hated the plant on the kitchen windowsill even though he had watered it twice this week.

Gon came into the kitchen barefoot, hair still damp from the shower, wearing one of Killua’s old shirts that mysteriously kept vanishing until Gon claimed they were part of "his" collection. The collar was stretched out on one side. The hem hung crooked over his sleep shorts. He looked half-awake and pleased with himself, which meant he had either remembered something important or forgotten something important and had not realized it yet.

Killua kept his eyes on his laptop.

Gon’s hand crept across the counter.

Killua did not move.

The mug lifted, and Killua waited.

Gon took one long, trusting sip.

His whole face collapsed.

“Ugh.”

Killua allowed himself one second of silence before he looked up. “Problem?”

Gon stared down into the cup like he expected it to taste any different. “That’s disgusting.”

“That’s mine.”

“Why would you do that to coffee?”

Killua reached across the counter and pushed the other mug toward him with two fingers. It stopped neatly against Gon’s wrist. “That’s why yours is right here, stupid.”

Gon looked at the mug. Then at Killua. Then back at the mug. His expression softened in that terrible way it did sometimes, quick and bright and unguarded, like Killua had done something more meaningful than remember how Gon took his coffee.

Which was ridiculous. Killua remembered everything. Two sugars if Gon was tired, one if he was trying to pretend he was being healthy, none if it was field coffee and he was about to drink it lukewarm from a thermos while crouched in the dirt looking at animal tracks. Oat milk, when they remembered to buy it. Regular milk when they did not. Cinnamon if Killua was in a good mood and wanted to be annoying about it.

“Thanks,” Gon said.

“Don’t thank me. Stop stealing my stuff.”

Gon took his actual coffee and drank from it like Killua had rescued him from the brink of death. “Your stuff tastes like melted candy."

“Then stop putting your mouth on it.”

Gon grinned over the rim of the mug. “You first.”

Killua shut his laptop a little harder than necessary.

Gon laughed, pleased with himself, and came around the counter. He did not ask before stepping into Killua’s space. He never did anymore. His hip bumped Killua’s knee. One hand landed on the back of Killua’s chair, the other reaching past him for the toast cooling on the plate.

Killua caught his wrist without looking.

“No.”

“I’m hungry.”

“There’s another piece in the toaster.”

“But this one’s ready.”

“This one’s mine.”

Gon leaned over his shoulder, chin briefly pressing into the messy crown of Killua’s hair. “Sharing is good for relationships.”

“Stealing from me is bad for your life expectancy.”

“That sounds like a threat.” Gon punctuated that with a kiss on the top of his head.

Killua froze for exactly half a second, which was embarrassing because Gon kissed him all the time. On the mouth, on the cheek, on the shoulder when he passed behind him, on the knuckles when Killua was driving and pretending not to like it. They had been together for four years. They had been living together for two years. Gon had seen him sick, furious, half-asleep, sunburned, and once, catastrophically drunk after a cruise trip in celebration of Leorio's graduation. A kiss on the top of his head should not have done anything.

It did anyway.

Gon stole the toast.

Killua let him because, unfortunately, he was a weak man.

“You’re going to be late,” he said.

Gon took an enormous bite and glanced at the clock on the microwave. “No, I’m not.”

“You said you wanted to be there by eight.”

“It’s seven-twelve.”

“You still have to pack your sample kit.”

“I packed it last night.”

“You packed half of it last night.”

Gon chewed slowly. His eyes shifted away. “I was going to finish this morning.”

“You were going to finish this morning, or you were going to remember in the car?”

“Those are both technically this morning.”

Killua got up, taking his coffee with him. “Unbelievable.”

“You love me.”

“I tolerate you under extreme circumstances.”

Gon followed him out of the kitchen, toast in one hand, coffee in the other. “Extreme circumstances like shared rent?”

“Extreme circumstances like emotional blackmail.”

“I don’t blackmail you.”

“You looked sad in a grocery store until I bought you a twenty-eight-dollar jar of honey.”

“That was local honey.”

“That was robbery!”

Gon’s laugh followed him down the hall.

Their apartment was not big, but in the space it had, they etched themselves into the surface.

That was how Killua thought of it sometimes, though he would never say that out loud where Gon could hear and make 'the' face. The apartment had started out as white walls, hardwood floors, and too many cardboard boxes stacked in the living room. Now it had Gon’s field boots by the door, Killua’s drafting table tucked near the window, two bikes hanging from the wall because Gon had insisted it was “efficient,” and then he hit his shoulder on the pedal three times in one week. The plant from Kurapika on the sill above the sink, still alive through some miracle of spite, and Gon talking to it when he thought Killua was not listening.

The bookshelf in the living room sagged under more than books. It held a chipped clay fox Gon had made on a pottery date and insisted looked like Killua. It did not. Next to it sat a smooth river stone from a camping trip where Gon had forgotten the tent stakes. There were postcards from Alluka and Nanika, one from Prague, one from Kyoto, one from a town in Oregon where they had apparently eaten the best pie of their life and written only, "You would hate it here", which meant they had loved it.

On the wall above the couch was a grid of photos. Their friends. Their trips. Leorio asleep with his mouth open at a New Year’s party. Kurapika standing ankle-deep in ocean water, pants rolled up, looking like he was about to rewrite the tide. Alluka and Nanika with matching sunglasses. Gon on a ferry with the wind tearing through his hair, laughing so hard his eyes were shut. Killua was in that one too, technically. He was at the edge of the frame, looking at Gon instead of the camera.

Gon said it was his favorite.

Killua passed the photo wall without looking at it too long.

He went into the bedroom and found Gon’s sample kit open on the floor, exactly as unfinished as predicted.

“Gon.”

From the hall: “I know.”

“You don’t even know what I’m going to say.”

“Drink water, pack sunscreen, stop being handsome and right?”

“Two out of three.”

“Which two?”

“Figure it out.”

Gon appeared in the doorway a moment later, still holding the toast. His eyes went to the kit, then to Killua’s face.

“I was getting there.”

“You packed binoculars, three empty sample tubes, and a granola bar wrapper.”

Gon came over and crouched beside him. His knee pressed against Killua’s. “The wrapper is not part of the kit.”

“Incredible. That fixes everything.”

“It was from yesterday.”

“Why was it still in there?”

Gon shrugged and reached for the neatly labeled case of vials Killua had set on the bed. “Maybe I wanted to study it.”

“The wrapper?”

“Human impact on natural spaces.”

“You are the human impact.”

Gon grinned. “And you love me.”

Killua looked at him.

Gon was close enough that Killua could see the faint line of pillow crease still pressed into his cheek. Close enough to smell his shampoo, citrus, and mint because Gon kept buying the one Killua liked and pretending it was a coincidence. Close enough that when he leaned forward to grab the field notebook, his shoulder brushed Killua’s chest.

“Unfortunately,” Killua said.

Gon’s grin softened. He reached out, thumb catching briefly at the corner of Killua’s mouth.

“Crumb,” Gon said.

“From the toast you stole.”

“Borrowed.”

“You ate it.”

Gon’s thumb lingered half a second too long, warm against Killua’s skin. Then he pulled back and tossed the notebook into the kit like he had not just reached into Killua’s ribcage and messed with important wiring.

Killua busied himself checking the list.

Sample tubes. Gloves. Field notebook. Portable charger. Sunscreen. Insect repellent. First aid kit. Water purification tablets, Gon probably would not need, but Killua had packed anyway. Extra socks because Gon had the survival instincts of a golden retriever near a puddle.

“You’re fussing,” Gon said.

“I’m preventing disaster.”

“You always call it that.”

“You always cause one.”

Gon leaned his head against Killua’s shoulder. Just dropped it there, heavy and trusting. Killua paused with one hand inside the kit.

“You don’t have to come today,” Gon said.

Killua zipped the kit shut. “I know.”

“It’s just a check-in. I’ll be done by lunch.”

“You said that last time and came home at nine with mud in your hair.”

“There were salamanders.”

“There are always salamanders.”

“That’s why someone has to check on them.”

Killua turned his head slightly. Gon’s hair tickled his jaw.

“You’ve been working late for two weeks,” Killua said.

Gon made a noise.

“That wasn’t an argument.”

“It was a grunt.”

Killua nudged him off with his shoulder, mostly because if Gon stayed there any longer, he would forget why he was supposed to be annoyed. “I’m coming.”

Gon looked at him for a moment, then smiled, small and private.

“Okay.”

Killua picked up the sample kit and shoved it into Gon’s chest. “Carry your own stuff.”

Gon caught it with a laugh. “Bossy.”

“You’re going to make us late.”

The framed prom tickets hung near the bedroom door.

They had argued about putting them there. Killua had wanted them tucked into the bookshelf where no normal human guest would notice them. Gon had insisted the hallway was better because “that way we can see them every day,” which was an objectively embarrassing sentence to say about prom tickets when they were twenty-five years old.

The frame held more than the tickets. Two blue rectangles with the school name printed in silver. A photo booth strip from the diner they had gone to afterward, both of them still in formal clothes and pretending they had not spent the entire night watching each other instead of dancing with literally anyone else. A dried white flower from Killua’s boutonniere, pressed flat and fragile behind the glass. A receipt for fries and milkshakes at one in the morning. A folded scrap of paper in Gon’s handwriting that said, " you looked stupid in the tie :) "

Killua had kept all of it in a shoebox for six years. Gon had found it when they moved in together.

He had been insufferable for a week. Then he had bought the frame.

Killua slowed for half a second as they passed it, like he always did. A bad habit. A worse comfort.

Gon noticed, like he always did.

“You’re looking at it again,” he said.

“I’m looking at the thermostat.”

“The thermostat is on the other wall.”

“The apartment is too warm.”

“You’re too warm.”

“That doesn’t mean anything.”

“It means you’re blushing.”

“I’m not.”

Gon bumped their shoulders together. “You were so cute at prom.”

“I was not cute.”

“You had that little silver tie.”

“You mean the tie I looked stupid in?”

“You did look stupid.” Gon reached ahead of him to grab his jacket from the hook by the door. “But in a cute way.”

“There is no cute way to look stupid.”

“You manage.”

Killua took the jacket and shoved his arms into it. “Keep talking, and I’m not buying you lunch.”

“You were going to buy me lunch?”

“No.”

“But you thought about it.”

“I thought about leaving you at the field site.”

Gon slipped past him to get his boots. “You’d come back.”

Killua watched him crouch by the door, struggling with the laces because he always tied them too tight, and then acted as if he had been personally betrayed when he had to untie them later.

Yeah, Killua thought.

He would.

In the kitchen, Gon had left the grocery list stuck to the fridge under a magnet from the first terrible apartment they had toured together. The one with the slanted floor and the bathroom door that did not close unless you lifted it with your foot. Gon had loved it for reasons no rational person could defend. Killua had vetoed it before the landlord finished saying “natural light.”

The list was written mostly in Killua’s handwriting, with Gon’s additions crammed into the margins.

eggs
rice
paper towels
dish soap
real vegetables
not just potatoes, Gon
honey????
coffee
coffee that doesn’t taste like dessert, Killua
snacks for field kit
restaurant friday? :)

Killua stared at the last line while Gon finished tying his boots.

“You looked up the menu?” Killua asked.

Gon glanced back. “For what?”

“The restaurant.”

“Oh. Yeah.” Gon stood, grabbing his keys from the little dish by the door. His keys were tangled with Killua’s spare bike lock key and the tiny, cracked whale charm from a vending machine in elementary school. Gon gave it to him easily, and he'd held it close ever since. “They have a bunch of stuff you can eat.”

“I can eat anything.”

Gon gave him a flat look. “You said your cacio e pepe was too spicy.”

“It was a lot of pepper.”

“It was normal pepper.”

“They have noodles without chili oil. And some grilled fish thing. And fried rice, but I think you’d have to ask for no peppers.”

Killua looked down at the grocery list again.

Gon had written restaurant friday? like a question, but he had already checked the menu. Already made sure Killua would not have to pretend his mouth was not on fire. Already picked three things that were safe and one thing he would try to bully Killua into tasting anyway.

Gon was reckless with his own body and stupidly precise with Killua’s comfort.

It was one of the reasons Killua loved him.

“You’re making the reservation,” Killua said.

Gon brightened. “So we’re going?”

“I didn’t say that.”

“You said I’m making the reservation.”

“For a hypothetical meal.”

“With a date and time?”

“Hypothetically.”

Gon crossed the apartment in two easy strides and kissed Killua’s cheek.

Killua scowled at him.

Gon only smiled wider. “Hypothetically, I’m excited.”

Killua rolled his eyes and grabbed the car keys. “Actually, get in the car.”

May sunlight caught on the windows across the street, turning every parked car into a briefly blinding mirror. Someone was walking a tiny dog in a sweater despite the warmth. A delivery truck idled at the curb. The coffee shop under their building had propped its door open, and the smell of espresso and baked sugar drifted out onto the sidewalk.

Gon lifted his face into the sun like a houseplant.

Killua unlocked the car. “You’re going to burn again.”

“I put on sunscreen.”

“When?”

“This morning.”

Killua stared at him over the roof of the car.

Gon opened the passenger door. “I thought about putting on sunscreen.”

Gon got in.

Killua did not.

He opened the back door instead, dug through his bag, and pulled out the small tube of sunscreen he had started carrying three summers ago because Gon had the skin-protection instincts of someone who wanted cancer to be approximately 20 years.

Gon watched him over the top of the passenger seat. “What?”

“Face.”

“I’m already in the car.”

“Tragic. Face.”

Gon sighed like Killua was asking something deeply unreasonable, but he turned toward him anyway. Killua squeezed sunscreen onto his fingers, leaned through the open door, and caught Gon’s chin before he could pretend this was optional.

“You’re so demanding,” Gon muttered.

“You’re so flammable.”

“I tan.”

“You freckle and complain.”

Gon’s mouth twitched.

Killua smoothed sunscreen over the bridge of his nose, across his cheeks, up along the warm line of his forehead. Gon closed his eyes without being told. Trusting. Annoyingly pleased about it, too, if the stupid little curve of his mouth meant anything.

Killua tried not to look at it.

“Ears,” he said, because sounding irritated was easier than feeling whatever the hell that was.

Gon obediently tilted his head.

“You love this,” Gon said.

“I love preventing you from turning into a tomato.”

“No, you love fussing over me.”

Killua rubbed sunscreen onto the tip of one ear with more force than necessary.

“Ow.”

“Hold still.”

Killua finished the other ear, then wiped the excess sunscreen down the side of Gon’s neck because he was already there and because Gon would forget and because the sun was going to hit that spot all morning.

Gon opened one eye.

Killua realized his hand had lingered.

He let go and stepped back. “There. Now get in properly.”

Gon grinned, bright and shameless. “Thanks.”

“Don’t thank me. Develop survival skills.”

Gon pulled the door shut, still smiling.

Killua rounded the car and got in like he had not just spent thirty seconds touching Gon’s face in the middle of the sidewalk with the casual entitlement of someone who had been allowed to for years. Then tossed the sample kit into the backseat and circled around to the driver’s side. Before he could put the key in the ignition, Gon had already connected his phone to the Bluetooth.

“No.”

“You don’t even know what I’m playing.”

“I know you.”

Music filled the car, bright and loud and aggressively cheerful. Some pop playlist hand selected by the gods of apple music.

Killua closed his eyes.

Gon laughed and turned it down by one single notch, which was apparently his idea of compromise.

The drive out of the city took them past grocery stores, apartment buildings, school zones, and a park where kids were already climbing over the playground equipment. Gon narrated half of it like Killua had not lived there for years.

“That bakery’s open again.”

“It was closed for two days.”

“They have those almond things you like.”

“I like one almond thing.”

“You like three.”

“You count?”

Gon looked at him like that was a stupid question. “Obviously.”

Killua kept his eyes on the road.

At a red light, Gon reached over and took his right hand from where it rested near the gearshift. He did it absently, like adjusting the radio or stealing fries. His fingers slid between Killua’s, warm from the coffee, thumb brushing the side of Killua’s knuckle.

Killua glanced at him.

Gon was looking out the window.

“You’re clingy today,” Killua said.

Gon lifted Killua’s hand and kissed his knuckles.

It was quick. Thoughtless. Barely a thing.

Killua’s grip tightened around the steering wheel anyway.

The light turned green.

Gon let go.

Killua put his hand back on the wheel and pretended he was not thinking about the shape of Gon’s mouth against his skin.

“You sure this is just a check-in?” he asked after a minute.

Gon groaned. “Yes.”

“You’ve been saying that all week.”

“Because it’s been true all week.”

“You came home after dark three times.”

“That was different.”

“How?”

“There were complications.”

“You mean you forgot to leave?”

Gon leaned his head against the window. “The survey area is bigger than we thought.”

“Then they need more people.”

“They’re trying.”

“You are not more people.”

“I’m very efficient.”

“You fell asleep in the shower on Tuesday.”

Killua resisted the urge to reach over and check his forehead, which was stupid because Gon was not sick. Tired, maybe. Overworked, definitely. Stubborn past the point of scientific classification, always.

He looked fine in the passenger seat. Better than fine. Sun across his cheek, one knee drawn up, fingers tapping absently against his coffee cup in time with the music. His hair had dried in uneven pieces, sticking up at the back where he had not bothered to comb it. There was a tiny smear of jam near his thumb from the toast.

Alive, Killua thought, in the careless way people thought things they had never had to question.

Gon caught him looking. “What?”

“Nothing.”

“You’re doing the face.”

“I don’t have a face.”

“You have like eight faces.”

“Name them.”

“Annoyed. Fake annoyed. Actually annoyed. Hungry annoyed. Worried but pretending to be annoyed. Sleepy and mean. About to say something romantic, but physically can’t. And the face you make when you see a dog wearing shoes.”

Killua stared at the road. “You’re such an idiot."

Gon’s smile was worth it.

Killua hated that smile. He loved it so much that it made him want to pick a fight.

The city thinned as they drove. Buildings gave way to lower roofs, then warehouses, then long stretches of road bordered by scrubby grass and drainage ditches glinting with leftover rainwater. The field site sat on the edge of a protected wetland threaded through with survey paths and low wooden markers. It was close enough to the city that Killua could still hear traffic in the distance when he parked, but far enough that Gon’s whole body changed the second he stepped out of the car.

He got brighter. There was no other word for it, which was annoying because Killua hated imprecise language and hated even more when imprecise language was the only thing that fit. Gon breathed in like the air was different here. Like standing water, sun-warmed grass, and dirt were all things his body had missed personally.

Killua got out and watched him sling the sample kit over one shoulder.

“Careful,” he said.

Gon looked back. “I haven’t even moved yet.”

“You’re thinking about moving recklessly.”

“You can tell?”

Killua shut the car door with his hip. “Unfortunately.”

The path into the site was narrow and still damp from last night’s rain. Grass brushed their knees. Small insects jumped away from their steps in flickers. Someone had tied orange flags to thin stakes along the rise leading toward the marsh, each one snapping lightly in the breeze. Beyond them, reeds shifted in silver-green waves, and dark water showed in pieces between the growth.

Gon started talking almost immediately.

Killua only understood about half of it, which was fine. He knew more about tensile strength and workflow systems than migratory corridors or amphibian populations. But Gon talked with his hands, with his whole body, pointing out bent stems, prints in the mud, the clean V of something’s movement through shallow water. He crouched near the path to show Killua a track that looked, to Killua, like a dent.

Gon crouched near the edge of the path before Killua could stop him, one knee sinking dangerously close to the mud as he leaned over a shallow print pressed into the wet ground. To Killua, it looked like a dent. Maybe a weird leaf. Maybe absolutely nothing. Gon, however, studied it with the kind of focus he usually reserved for living things, his head tilted, and his mouth curved faintly in concentration.

“Raccoon,” Gon said.

Killua stopped beside him and looked down at the mark again.

“Sure.”

Gon glanced up immediately. “It is.”

“I said sure.”

“You said it like you don’t believe me.”

“I believe you professionally,” Killua said.

Gon’s eyes narrowed. There was dirt on the side of his boot already. They had been out of the car for less than five minutes. “But not emotionally?”

Killua considered the print with all the seriousness it deserved, which was none. “I am emotionally neutral on raccoons.”

Gon looked personally wounded by that. Actually wounded, like Killua had insulted an old friend. “That’s sad.”

“Raccoons have done nothing for me.”

“They exist.”

“So do parking meters.”

Gon huffed, but it broke halfway into a laugh. He was still crouched in the mud, sunlight caught warm in his hair, one hand braced against his knee while the other hovered carefully over the print like touching it would ruin something important. He looked ridiculous. He looked happy. He looked exactly like himself, which was worse, somehow, because Killua had come here prepared to be annoyed and instead felt his chest do something embarrassingly soft.

“You’re impossible,” Gon said.

“You’re crouching in mud before nine in the morning.”

Gon tipped his face up toward him, grin going bright and smug. “You came with me.”

Killua looked away first, because there were some things a person could survive and some things he should not be expected to endure before breakfast.

“Someone has to make sure you don’t die in a ditch.”

“Romantic.”

Killua nudged the edge of Gon’s boot with his own, careful not to actually throw him off-balance even though Gon deserved it. “Get up.”

Gon stood too fast. It was barely anything at first. Just a small interruption in the rhythm of him, a missed beat where there should have been motion. His smile stayed in place, still easy, still bright from whatever argument he thought he had won, but his eyes lost focus for half a second. One hand went to the strap of the sample kit and gripped it tighter than he needed to.

“Gon.”

Gon blinked, like the sound of his name had pulled him back from somewhere a few steps away. “What?”

Killua gave him a look.

Gon’s mouth twisted, already sheepish. “I’m fine.”

“I didn’t ask.”

“You were going to.”

“Because you did the thing.”

“What thing?”

“The thing where you pretend you’re not dizzy.”

Gon looked away at that, which was answer enough. His thumb rubbed absently over the strap of the kit, back and forth, back and forth. The breeze pushed through the grass around their legs. Somewhere out in the reeds, something shifted and went quiet.

“It was just for a second,” Gon said.

Killua stepped closer. “Did you eat anything besides my toast?”

“Our toast.”

“Gon.”

“And a bar.”

“When?”

Gon paused for too long.

Killua closed his eyes and pinched the bridge of his nose. “I swear to god.”

“I was going to eat after this section.”

“You were going to eat now.”

“I have to check the markers first.”

“You have to sit down first.”

Gon sighed like this was a great injustice being committed against science itself, but there was affection under it. There always was, even when he was being impossible. Especially then. “You’re being so bossy today.”

Killua shoved the water bottle into his hand before Gon could argue himself into another circle. Gon took it with a look of exaggerated suffering, then drank like hydration was something being done to him against his will. Killua watched the movement of his throat, the color in his face, the slight tremor in his hand as it steadied around the bottle.

Too pale, maybe. Or maybe Killua was looking too hard.

That was the problem with loving Gon. There was no clean line between paying attention and worrying himself sick. Gon made a face when he lowered the bottle, wiping his mouth with the back of his hand before giving Killua a look over the rim.

“See?”

Killua did not move. “I see a guy who needs a snack.”

“You always see a guy who needs a snack.”

“I’m always right.”

Gon laughed, and the sound traveled like bells over the wetland, warm enough to scatter the tightness gathering under Killua’s ribs. Something small startled from the reeds and vanished deeper into the grass. Gon turned his head to follow it, attention already catching on the world again, already trying to slip away from the fact that his body had asked for a break.

Killua rolled his eyes and reached into the kit for a granola bar.

He would make Gon eat. Then Gon would check his markers, because stopping him entirely would be more trouble than it was worth, and then they would go home. Gon would shower for too long and leave mud in the tub. Killua would complain and clean it anyway. They would buy groceries, maybe. Or order from the restaurant if Gon smiled at him enough. Friday, Gon would make the reservation and pretend it had not been his plan all along.

There was time.

Killua had the granola bar halfway out of the pocket when Gon said, “Whoa.”

Not loud, just confused.

Killua looked up.

Gon had gone still.

The smile was gone from his face now. His brows drew together, but his eyes were unfocused again, worse this time. Farther away. His right hand lifted like he meant to catch himself on something that was not there.

The granola bar slipped from Killua’s fingers.

“Gon?”

Gon turned toward him.

For one impossible second, he looked embarrassed. Like he knew he had scared Killua. Like he was about to apologize for it.

Then his knees buckled.

Killua moved.

He was fast. He had always been fast, faster than most people expected, faster than Gon liked to admit when they were being competitive about stupid things. He crossed the distance between them before the water bottle hit the ground, before Gon’s body had fully tipped forward, before the first real spike of panic could even finish forming in his chest.

It still was not enough.

His hand caught Gon’s jacket, fingers twisting hard into the fabric, and for one split second, he thought he had him. Gon’s weight pulled against his arm. The sample kit slipped from Gon’s shoulder and hit the mud with a heavy, wet sound. Killua planted his foot, dragged him back, and tried to turn them both away from the uneven edge of the path.

But Gon was heavier than fear made him look. His body had gone strange and loose in Killua’s grip, all the reckless, stubborn force of him disappearing at once. Killua got an arm around his waist, half-catching him, half-falling with him, and then Gon’s shoulder struck the ground. His head hit a flat stone half-buried at the edge of the trail with a sound Killua knew he would hear for the rest of his life.

Killua dropped with him, one knee sliding in the mud. For a second, everything narrowed down to stupid, useless details. The reed bent beside Gon’s cheek. The dark smear of water is soaking into Killua’s jeans. The granola bar was lying open in the dirt, its wrapper flashing silver in the sun.

Then Gon’s body jerked.

Killua’s hands froze above him.

“Gon?” His voice cracked on it. He did not care. “Gon, hey. Hey, look at me.”

His eyes were open, but they were not focused. His jaw had gone tight. One of his hands curled hard against his chest, fingers rigid, and Killua’s brain emptied so completely that for half a breath he was twelve years old again, watching something terrible happen and waiting for someone older to tell him what to do. No one did.

“Shit,” Killua said, and then louder, because sound was the only thing he had. “Shit, shit, Gon.”

He reached for his phone with fingers that did not feel like his. It was in his pocket. No, not that pocket. Jacket. Back pocket. His hand slipped once because of the mud. He almost dropped it.

Emergency services answered after what could not have been more than two rings.

Killua told them his name. Their location. The field access road. Wetland preserve, north entrance, marker signs, no, not on the main trail, maybe three hundred yards in. He heard himself speak in clipped, steady pieces, like his voice belonged to someone else. Male, twenty-five, seizure or collapse, head impact, bleeding, breathing but unresponsive.

Bleeding.

There was blood in Gon’s hair.

Not a lot, he thought wildly. Not enough. Too much. Anything was too much. It had threaded through the dark strands near his temple and into the mud beneath him, bright where the sun caught it. Killua pressed the heel of his hand against the ground instead of touching it because the dispatcher was telling him not to move Gon unless he had to, not to restrain him, to keep the area clear, to time the seizure if he could.

Killua looked at his phone screen and could not understand the numbers.

“He hit his head,” he said again, because maybe if he said the worst part enough times, someone would arrive faster. “He hit his head. I tried to catch him.”

The dispatcher’s voice stayed calm. Killua hated her for it and clung to it anyway.

Gon’s body jerked again, then went still.

Too still.

Killua bent over him so fast his own vision tunneled. “Gon? Gon, breathe. Come on.”

“He’s breathing,” the dispatcher said, because Killua must have said something out loud. “Can you see his chest moving?”

Killua looked. For one second, he could not.

Then Gon’s chest rose shallowly under his jacket.

“He’s breathing,” he said.

“Good. Keep monitoring him. Help is on the way.”

Help is on the way. The sentence should have meant something. It should have opened a door. Instead, Killua knelt in the mud with one hand hovering uselessly near Gon’s shoulder and understood, with a clarity so sharp it almost felt calm, that help could be on the way and still be too late.

He had been right there.

He had been right there. He had been watching Gon, worrying about him, scolding him, making him drink water, digging a granola bar out of the kit like that was the solution to anything. He had seen the first dizziness.

And it still happened.

Gon’s lashes trembled.

Killua leaned closer, heart climbing into his throat. “Gon?”

For a moment, Gon’s eyes moved under half-lowered lids, searching without landing. His lips parted around a sound too faint to be a word.

“I’m here,” Killua said immediately. “I’m right here. Don’t move, okay? Don’t try to get up.”

Gon did not answer.

The first siren reached them thinly through the wetland, distorted by distance and wind. Killua turned his head toward it like he could drag the ambulance closer by looking hard enough. His hand found Gon’s wrist, two fingers pressing against his pulse because the dispatcher had said not to crowd him and not to move him and not to do half the things Killua’s entire body was screaming to do.

Gon’s pulse beat under his fingers.

Fast. Alive.

Killua held onto that because there was nothing else.

By the time the paramedics reached them, Killua had mud on both knees and blood on the side of his hand. He did not remember getting it there. He did not remember if Gon had opened his eyes again or if he had imagined it because he needed to. He remembered being moved aside by someone with kind eyes and blue gloves. He remembered standing because someone told him to, then immediately crouching again because the ground tilted under him.

He was asked questions.

Age. Twenty-five. Known medical conditions. None that Killua knew. Medications. No. Allergies. Shellfish. The accident. Dizziness, collapse, seizure, and head strike. How long did the seizure last? Killua did not know. He should know. He had been told to time it. He had looked at the screen. He had not understood the numbers.

“I don’t know,” he said, and the failure of it nearly split him open. “I don’t know. Maybe two minutes. Maybe less. I don’t know.”

“That’s okay,” one of the paramedics told him.

They loaded Gon onto a stretcher with a brace around his neck, and Killua followed so closely someone had to tell him to step back again. Gon looked wrong under the straps. Too still. Too pale beneath the mud and blood. One of his boots had come untied.

Killua stared at the loose lace until a paramedic asked if he was family.

“Yes,” Killua said.

No hesitation. No thought.

The word left his mouth before any of the paperwork of their lives could catch up. Before boyfriend, partner, emergency contact, roommate, best friend. Yes. Family. The only answer that mattered.

They let him into the ambulance.

A hand braced against the wall. Someone is checking Gon’s pupils. The sharp smell of antiseptic wipes. A monitor is beeping near Killua’s shoulder. Questions are coming too fast and also too slowly. Gon’s name was said again and again by people who did not know the way it should sound.

Killua sat where they told him to sit. He kept his hands clasped so hard his knuckles ached because he was afraid that if he moved, he would touch something he was not supposed to touch. The ambulance turned, and his shoulder hit the wall. He barely felt it.

“Can he hear me?” he asked.

One of the paramedics glanced up. “Maybe.”

Maybe.

Killua swallowed around something jagged. He leaned forward as far as the seatbelt allowed.

“Gon,” he said, and hated how small his voice sounded under the siren. “You’re okay. You hear me? You’re okay.”

Gon did not move.

Killua’s fingers dug into each other.

“You’re going to be fine,” he said, because lying to unconscious people probably did not count. “And when you wake up, I’m going to kill you.”

The paramedic closest to Gon looked at him for half a second.

Killua did not explain.

Gon would have understood.

At the hospital, everything blurred. The doors opened. The stretcher rolled out. Someone told Killua to wait. He did not. Or he tried not to. Or he took three steps after them before a nurse intercepted him with a gentleness that made him want to tear the walls apart.

“We’re going to take care of him,” she said.

“You don’t understand,” Killua said.

It came out flat.

The nurse’s face changed slightly, not enough to be pity, but close. “I know it’s scary.”

No, Killua thought. You don’t.

Because scary was too small. Scary was a noise in the dark. Scary was a near miss. Scary was Gon laughing afterward and saying, “See? I’m fine,” while Killua threatened to never let him out of the apartment again.

This was something else. This was the world opening under his feet and asking him to keep standing. They took Gon through a set of doors that Killua was not allowed to follow.

For a while, there was only waiting.

The emergency department waiting room did not feel cruel. That almost made it worse. No one was trying to be unkind. The lights were warm enough. The walls were painted a soft beige with framed prints of desert flowers spaced evenly between laminated signs. A television mounted high in one corner played a cooking show with the captions on. Nurses passed in soft shoes, carrying clipboards, tablets, and paper cups of water.

Everything was ordinary.

Killua sat in a bolted chair with mud drying on his jeans and Gon’s blood under one fingernail.

He tried to clean it off in the bathroom after the first hour. The soap smelled like fake lemons. He scrubbed until the skin around his nail went red, until an older man washing his hands at the next sink glanced over and then quickly away. The blood did not come out all the way.

When Killua returned to the waiting room, his phone had twelve missed calls.

Alluka. Leorio. Kurapika. Alluka again. A number from Gon’s workplace. Leorio again.

He should call them. He knew that. Gon had people. Gon was loved loudly and inconveniently by half the city. There were people who needed to know. People who would come. People who would ask him questions for which he did not have answers.

Killua opened Alluka’s contact, then closed it.

He could not say it yet. Saying it would make it larger. Saying it would turn Gon from a body behind hospital doors into a story Killua had to tell. So he texted instead, because text was survivable.

accident at the field site. hospital. will call when I know more.

He sent it to Alluka first, and everyone followed after.

Then the doors opened, and a doctor stepped into the waiting room with Killua’s name in his mouth.

Killua stood so fast his phone fell from his lap and clattered against the floor.

The doctor was younger than Killua expected. Not young, exactly, but not old enough to contain what had happened. He had tired eyes and a careful voice, the kind people used when they had already decided which words might break you least.

“Gon is stable,” he said first.

Killua heard nothing after that for three seconds.

Stable.

Not fine. Not awake and complaining. Not asking for him. But stable.

The doctor led him to a quieter stretch of hallway near a row of empty consultation rooms. Killua followed with his phone clenched in his hand and dirt still flaking from the knees of his jeans. His mouth tasted like metal.

“He experienced a seizure,” the doctor said. “From what you described, it may have started before the fall. The head injury complicated things, but the imaging is reassuring in some ways.”

“In some ways,” Killua repeated.

The doctor’s expression did not shift much. “There is a bleed near the temporal lobe. It appears stable right now, and we’re monitoring it closely. He also has a concussion from the fall.”

Killua looked at him.

The words made sense individually. Together, they refused to become anything useful.

“Is he awake?”

“He’s been in and out. Responsive at times. Confused, which is expected with the seizure and head trauma.”

“Confused how?”

The doctor paused.

Killua hated the pause before he even knew what came after it.

“He’s having some memory disruption,” the doctor finally continued. “Patchy retrograde amnesia. That means there are gaps in his memory of events before the injury.”

Killua’s grip tightened around his phone.

“How far before?”

“It’s not cleanly organized. Memory loss after this kind of event can be uneven. He remembers some things clearly, especially older memories. Childhood, adolescence, long-standing relationships. But more recent years seem less consistent.”

Long-standing relationships. The hallway seemed to narrow.

“He knows me,” Killua said.

It was not a question.

The doctor nodded carefully. “He knows you.”

Killua almost snapped at him then. Almost said, of course, he knows me. Of course, he knows me; that is not the part you are supposed to look uncertain about.

But the doctor kept speaking.

“He identified you as his best friend.”

Something inside Killua went very quiet.

Best friend.

The words should not have hurt. They were true. They had been true for more than half his life. Once, they had been the most important words in the world. Once, Killua would have taken them and held them against his chest like proof he had a place in it. But now, it sounded like a demotion made by someone who had no idea what he was taking away.

Killua’s throat moved.

“He said that?”

“He was asked who you were,” the doctor said. “That was his answer.”

For a moment, Killua could not remember how to breathe normally. He was aware of the hospital around him in separated pieces: the scuff on the baseboard near the doctor’s shoe, the distant rattle of a cart, the ache in his own jaw from clenching it too hard.

Best friend.

Not boyfriend.

Not partner.

Not the person whose name was on every emergency form Gon had filled out for the last four years. Not the person Gon had kissed over coffee that morning. Not the person Gon had planned dinner around because he remembered Killua hated too much spice.

Best friend.

Killua made himself ask, “Will it come back?”

The doctor exhaled softly through his nose. Not a sigh. Worse. A preparation.

“It’s difficult to say.”

Killua looked at him sharply. “That’s not an answer.”

“I know.”

“Then give me one.”

“I can’t promise you that all of it will return. Some memories may come back over days or weeks. Some may come back in fragments. Some may not. We’ll know more as the swelling decreases and he rests.”

Rest. The word was so useless, Killua wanted to throw it at the wall.

“What do I do?”

The doctor’s face softened in a way Killua did not want. “Keep things calm. Familiar. Don’t overwhelm him with too much information at once. Don’t try to force memories. It can increase distress and confusion. Let him ask questions, answer gently, and give him time.”

Killua almost said, He hates time.

Instead, he asked, “Can I see him?”

“In a few minutes. A nurse is finishing with him now.”

Killua nodded once.

The doctor hesitated. “I’m sorry.”

Killua looked down at his hands. There was still blood beneath his nail.

He thought of Gon standing in the kitchen that morning with Killua’s coffee in his hand, making a face at the sweetness. Gon is kissing the top of his head. Gon is laughing in the field with sunlight in his hair.

Then he thought of the way Gon’s head had hit the stone.

“I was right there,” Killua said.

The doctor was quiet.

Killua had not meant to say it out loud. Once it was there, he could not stop hearing it.

I was right there.

He pressed his thumb hard against the edge of his phone until the corner bit into his skin.

“I was right there,” he said again, lower this time.

The doctor did not tell him it was not his fault. Maybe he was smarter than he looked.

A nurse came for him a few minutes later. Or maybe ten. Or maybe thirty. Time had stopped behaving like something measurable.

Killua followed her through the doors.

The hallway beyond the waiting room was quieter, not silent. Monitors beeped from behind curtains. Someone coughed. A nurse laughed softly at something another nurse said, the sound ordinary and human. Killua walked past all of it with his hands in his pockets so no one would see how badly they were shaking.

“He’s tired,” the nurse told him. “He may repeat questions. That’s normal right now.”

Normal. Killua nodded because he had no safe response to that.

The nurse pulled back a curtain.

Gon was awake.

For one second, relief hit so hard that Killua almost stumbled.

Gon was propped against the pillows, hair cleaned as much as they could manage but still dark and uneven near the bandage at his temple. There was a bruise starting high on one cheekbone. An IV line ran into his arm. He looked pale and exhausted and small in a way Killua had never associated with him, but his eyes were open.

His eyes found Killua.

And then Gon smiled.

Not big. Not his usual sun-out, whole-face, impossible thing. Just a tired curve of his mouth, soft with recognition.

“Killua,” he said.

Killua’s chest cracked straight down the middle.

He stepped closer before he could stop himself. “Hey, idiot.”

Gon’s smile widened a little.

Still Gon, still there.

Killua held onto that with both hands, even as the doctor’s words moved under his skin like glass.

He knows you.

Gon looked him over, slow and careful, like he was trying to put together the pieces of Killua’s face. His gaze caught on the mud drying on Killua’s jeans, the red scrape on his hand, the jacket twisted wrong from hours of being grabbed and pulled and forgotten.

“You look awful,” Gon said.

Killua let out something that was almost a laugh, but not close enough.

“Yeah,” he said. “You should see the other guy.”

Gon’s brow furrowed.

For half a second, Killua thought he had confused him, that the joke had landed wrong, that even this had been taken too.

Then Gon huffed softly.

“Was the other guy me?”

Killua’s throat went tight.

“Unfortunately.”

Gon closed his eyes for a moment, still smiling faintly. “That sounds right.”

Killua pulled the chair closer to the bed and sat down because his legs were starting to feel unreliable. The nurse told them she would be nearby and left the curtain half-open behind her.

For a moment, neither of them spoke.

Killua wanted to hold him. He wanted to take Gon’s hand. He wanted to smooth the hair back from his forehead, careful around the bandage. He wanted to put his mouth against Gon’s knuckles and feel the pulse there for himself. He wanted to climb into the stupid hospital bed and wrap himself around Gon until the shape of him made sense again.

He did none of it.

Gon watched him from the pillow, eyes heavy but attentive.

“What happened?” he asked.

Killua took a breath. He could answer this. This part was safe. This part had facts.

“You had a seizure at the field site,” he said. “You fell and hit your head. They brought you here. The doctor said there’s a small bleed, but it’s stable. You have a concussion.”

Gon absorbed that quietly. His gaze drifted toward the ceiling, then back to Killua. “A seizure?”

“Yeah.”

“That’s weird.”

Killua stared at him.

Gon’s mouth twitched weakly. “Bad weird.”

“You think?”

“Don’t sound so mad. I didn’t do it on purpose.”

The anger went through Killua fast and helplessly, burning itself out before it could find anywhere to go. “You scared the shit out of me.”

Gon looked at him then. The apology was there before he said it, softening his whole face. “Sorry.”

Killua’s hands curled against his knees.

“Don’t apologize,” he said.

“Just did.”

“Yeah, and it was stupid.”

Gon’s smile came back for half a second. Then it faded into something more uncertain.

“Was I working?”

Killua nodded. “Yeah.”

“At the wetland site?”

“Yeah.”

Gon’s brow drew in slightly. “Why were you there?”

The question was quiet. Perfectly reasonable.

There were machines around them, soft footsteps beyond the curtain, the distant ring of a phone at the nurses’ station. Gon was looking at him with total trust, waiting for Killua to fill in the blank the injury had left behind.

Why were you there?

Because you asked me to come.

Because you’ve been working too much.

Because I wanted to spend the day with you.

Because we were going to buy groceries after.

Because we live together.

Because I love you.

Because you love me.

The doctor’s voice moved through him again.

Don’t overwhelm him. Don’t force memories.

Let him ask questions. Answer gently. Give him time.

Killua looked at Gon’s tired face, the bandage at his temple, the confusion he was trying so hard to hide.

And beneath all of that, uglier and quieter, something else opened its eyes.

What if Killua told him?

What if he said boyfriend, partner, love of your life, mine mine mine, and Gon stared at him like a stranger? What if Gon believed him because everyone said it was true, not because he felt it? What if Gon woke up with four years missing and a relationship placed in his lap like a bill he did not remember signing?

Killua had always known how to survive by not wanting things and not asking for them.

“We’re roommates,” he said.

Gon blinked once.

“Oh,” he said.

Killua felt the sentence settle between them.

Wrong shape. Wrong weight. Too small to hold what it had been given.

Gon seemed to turn it over in his head, testing it against whatever pieces he still had. Best friends. Years. Killua is beside him in a hospital. Killua at the field site. Killua knows things. Killua there.

Then Gon nodded faintly.

“Okay,” he said. “That makes sense.”

Killua’s heart did something horrible.

Gon trusted him. Of course he did.

Killua looked down at his own hands before Gon could see whatever had happened to his face.

“Yeah,” he said. “It does.”
