Work Text:
The thing about Narumi Gen was that he never did anything halfway.
If he liked something, everyone knew.
If he hated something, everyone knew.
If he wanted something—
Well.
Hoshina Soshiro had spent years trying not to think too hard about that one.
Their rivalry had started easily enough. Narumi had been impossible not to notice: loud where Hoshina was quiet, brilliant where Hoshina was slippery, forever turning every exercise into a contest and every contest into a personal challenge. Hoshina had answered in kind. If Narumi sharpened a joke, Hoshina sharpened his smile. If Narumi reached for the highest score, Hoshina found some sideways route to beat him there. Neither of them had ever been willing to call it affection. Rivalry was safer. Rivalry had rules.
They had spent years circling each other in that narrow space between antagonism and admiration, learning every weakness without ever admitting how carefully they watched for them. Narumi knew when Hoshina was tired by the way he held his shoulders. Hoshina knew when Narumi was worried by how quickly he started talking. They knew when the other was lying, and they kept letting the lies stand.
Because lately, Narumi had been doing something much worse than wanting.
He had been hesitating.
It was late when Hoshina found himself alone in the First Division headquarters’ break room, stirring a cup of tea that had gone cold. The place had settled into its nighttime quiet: the low, constant hum of machinery in the walls, the occasional echo of boots on the corridor floor, the faint electrical buzz of lights that had never been designed for comfort.
Hoshina liked the hours after midnight. There was less noise, fewer people looking at him, fewer chances for someone to ask whether he had eaten or slept.
It was also a convenient time to visit the First Division without having to explain himself too closely. There was always an excuse ready if anyone asked: a report to deliver, a weapons adjustment to discuss, some minor detail from a shared operation that could not possibly wait until morning. The excuses were usually plausible. They were never necessary.
He could have sent a message. He could have waited for Narumi to come to him. Instead, he kept finding reasons to cross the headquarters, to appear in the First Division’s corridors with a file tucked under his arm and a look of mild irritation already prepared. Sometimes Narumi wasn’t there. Those visits were easy to dismiss as bad timing.
The ones where Narumi was there were harder.
He was halfway through deciding that cold tea was still preferable to conversation when the door opened.
“You still awake?”
Narumi.
Hoshina didn’t look up. “Unfortunately.”
Narumi walked over and dropped into the chair across from him. He looked exhausted. His hair was a mess, his uniform jacket hung loosely from his shoulders, and there were faint shadows beneath his eyes that even his usual arrogance couldn’t conceal.
Hoshina raised an eyebrow. “Captain of the First Division looking this pathetic? Shocking.”
“Shut up.”
“Touchy.”
Narumi leaned forward, resting his chin against one hand. His other hand drummed against the table, quick and restless. For a while, neither of them spoke.
It should have been comfortable.
It usually was.
They had known each other long enough to understand silence as a language. Tonight, neither of them seemed certain what the quiet meant.
Something had changed between them, something neither wanted to name. Naming a thing gave it shape, and a shape could be lost.
Narumi finally broke the silence.
“You ever wonder what it’d be like?”
Hoshina glanced at him. “What?”
“If we weren’t us.”
Hoshina’s fingers stopped moving around the cup.
Narumi stared down at the table as if the answer might be hidden in its scratches. “No ranks. No divisions. No stupid rivalry.” He gave a quiet, humorless laugh. “Just us.”
Hoshina smiled faintly. “Sounds boring.”
“Yeah.”
Narumi’s smile faded almost immediately. “Probably.”
The machinery hummed. Somewhere beyond the wall, a door closed.
“I think I’d like it,” Narumi said.
Hoshina’s chest tightened.
He looked away, fixing his attention on the untouched tea. “Don’t say things like that.”
“Why?”
“Because.”
“Because what?”
Hoshina didn’t answer. The answer was too obvious, and too dangerous. Because if Narumi said things like that, Hoshina might start believing him. Because he was tired of pretending that their arguments were only arguments, that every challenge was only a challenge, that the space between their shoulders when they stood side by side was not something either of them noticed.
Their rivalry had given them a language for wanting each other’s attention without having to ask for it. Beat me. Keep up. Try harder. Look at me. Hoshina had spent so long translating those demands into something safer that he no longer knew which words belonged to the game and which belonged to them.
Because Hoshina knew what Narumi sounded like when he was joking, and this wasn’t it.
Narumi leaned back. Frustration pulled at his features. Not anger. Something worse: the look of a man with a thought sitting behind his teeth, too large to spit out and too sharp to swallow.
“You’re always doing that.”
“Doing what?”
“Pulling away.”
Hoshina laughed softly. “Coming from you?”
“Yeah.”
Narumi looked straight at him. “From me.”
That made Hoshina quiet.
Narumi had always been good at reaching for things—victories, attention, the last word. He wanted proof, wanted acknowledgment, wanted Hoshina to look at him and admit that he was there. But when it came to Hoshina, he kept stopping just short, as if even Narumi could recognize the danger of winning something that might matter.
Maybe Hoshina did the same. He came to the First Division with excuses folded neatly into his pocket, lingered in doorways, and left before the wanting became visible. He told himself he was checking on shared work. He told himself Narumi was simply the most interesting person in the building to argue with.
He never told himself the truth for long.
Narumi stood. For one second, Hoshina thought he was leaving. The sensible thing would have been to let him go. The sensible thing was usually to make a joke, offer a sharp comment, and put another layer of distance between them.
Instead, Narumi walked around the table and stopped beside him.
He didn’t touch Hoshina. Didn’t even try. He simply stood there, close enough that Hoshina could feel the warmth coming off him, close enough to catch the faint scent of detergent and metal and the cold night air clinging to his jacket.
“I don’t need much,” Narumi said quietly.
Hoshina’s eyes lifted.
Narumi swallowed. “Just…”
His voice became almost embarrassingly soft.
“Just a little.”
Hoshina stared at him. “A little what?”
Narumi looked away, suddenly fascinated by the far wall. “Time.”
A beat.
“Attention.”
Another.
“Something.”
Hoshina’s expression softened before he could stop it.
“Gen.”
“I know.”
“You don’t get to ask for something small when you know damn well I’ll give you everything.”
Narumi froze.
Hoshina regretted the words the instant they left him. The room became painfully quiet, the kind of silence that pressed against the eardrums.
Then Narumi smiled.
It wasn’t his usual smug grin. It was smaller, uncertain at the edges. Almost sad.
“Everything?”
Hoshina looked down. “...Don’t push it.”
Narumi crouched beside his chair so they were eye level. The movement was so uncharacteristically careful that Hoshina’s pulse jumped. Narumi rested his forearm against his knee and studied him, no bravado left in his face now.
“I won’t,” he said.
For once, he meant it.
He reached over and gently hooked his pinky around Hoshina’s.
Nothing more.
No grand confession. No promises. No demand for an answer Hoshina wasn’t ready to give.
Just that tiny bit of contact.
Hoshina stared at their hands. Narumi’s little finger was warm against his, the contact absurdly delicate for someone who had spent most of his life treating every obstacle like it had personally insulted him.
Then Hoshina sighed.
“...You’re annoying.”
“Yeah.”
“Selfish.”
“Probably.”
“Needy.”
“Definitely.”
The corner of Hoshina’s mouth twitched. He tightened his pinky around Narumi’s.
“Stay five minutes.”
Narumi blinked. “That’s it?”
“Don’t get greedy.”
Narumi smiled. “Okay.”
Five minutes.
That was all Hoshina offered.
And somehow, Narumi stayed much longer.
At first, they simply remained there, connected by one finger like two people testing the strength of a bridge. Hoshina let Narumi keep his hand. Narumi let Hoshina pretend that this was not a concession of staggering proportions.
After a minute, Narumi shifted to sit on the edge of the couch along the wall. Hoshina followed a moment later, carrying his cold tea with him out of habit. He sat at the opposite end, leaving enough space between them for another person.
Narumi eyed the gap.
“Really?”
“You agreed not to get greedy.”
“I agreed not to push.”
“That’s the same thing.”
“It absolutely isn’t.”
“Your vocabulary is showing its limits.”
Narumi snorted, and just like that, the tension eased. Hoshina leaned back into the cushions, eyes half-lidded. The couch was old, slightly lumpy, and far too small for anyone to sleep on comfortably. It was also warm from the heating vent beneath it.
Narumi sat beside him, their shoulders barely touching.
They talked about nothing: a misfiled mission report, a junior officer who had lost three sets of keys in one day, the terrible vending-machine coffee. Narumi complained about everything with the conviction of a man delivering a formal indictment; Hoshina interrupted whenever the performance became too sincere.
It was easy.
That was the problem.
Five minutes became twenty. Twenty became an hour. The clock above the door crept forward while Narumi’s voice gradually grew quieter. He was still talking, but his sentences had begun to trail off at the ends. His head tipped back against the couch, eyes closing for a few seconds at a time.
“You should sleep,” Hoshina said.
Narumi opened one eye. “You should stop giving orders.”
“I’m not giving an order.”
“Sounds like one.”
“It’s advice.”
“Worse.”
Hoshina hummed. “Fine. Collapse wherever you like.”
Narumi’s eyes closed again. “Here’s good.”
Hoshina turned his head. “You’re not seriously planning to sleep on me.”
“Didn’t say anything about you.”
“Your head is already leaning.”
Narumi’s head was, in fact, leaning. Gradually, with the stealth of someone hoping to claim a territory without being noticed, it had drifted toward Hoshina’s shoulder.
Hoshina considered moving.
He didn’t.
Narumi settled against him with a quiet exhale. The weight was surprisingly light. Hoshina could feel the slow rhythm of his breathing through the fabric of his uniform. For a while, he listened to it instead of the machinery in the walls.
He should have felt victorious. Narumi Gen, rendered harmless by fatigue. The great captain of the First Division reduced to a warm, inconvenient weight against his side.
Instead, Hoshina felt something inside him unclench.
“You’re a pain,” he murmured.
Narumi, apparently not asleep after all, said, “You like me.”
Hoshina’s gaze remained fixed on the opposite wall. “That’s a strong word.”
“You told me you’d give me everything.”
“I was being dramatic.”
“You’re always dramatic.”
“Look who’s talking.”
Narumi’s mouth curved against his shoulder. “So you do like me.”
Hoshina looked down at him. “You’re enjoying this far too much.”
“Obviously.”
“You’re also not very good at staying quiet.”
“Never claimed to be.”
The room settled around them again. This silence was different, softer. Narumi’s hand rested in his lap, close enough that their knuckles brushed when Hoshina shifted.
Hoshina looked at it for a long moment.
Then he reached over and turned Narumi’s hand palm-up.
Narumi went still.
Hoshina traced the rough line of an old callus near his thumb, then another along his palm. The marks of training, missions, weapons held too tightly. Evidence of all the things Narumi did halfway only in his sleep.
Narumi’s voice came out lower. “What are you doing?”
“Inspecting the damage.”
“Looks bad?”
“Terrible.”
“Can it be fixed?”
Hoshina’s thumb paused over his palm. “Dunno.”
Narumi turned his hand, catching Hoshina’s fingers. “You could try.”
There it was again—that almost-question. Not an order. Not a demand. An opening.
Hoshina could close it. He had made a career out of closing doors before anyone else noticed they were open.
Instead, he said, “You’re very persistent.”
“Yeah.”
“Even when you’re scared?”
Narumi’s expression changed.
Hoshina had not meant to say it. Or perhaps he had. Perhaps the words had been waiting in the same place as everything else.
Narumi looked toward the clock. “I’m not scared.”
“Liar.”
“I’m tired.”
“That too.”
Narumi’s fingers tightened around his. “If I say what I want, you’ll laugh.”
“I might.”
“If I ask for more, you’ll disappear.”
Hoshina’s throat tightened.
Narumi’s fingers tightened around his. “See? I’m right.”
“No,” Hoshina said. “You’re an idiot.”
“Also true.”
Hoshina shifted toward him. Narumi lifted his head from Hoshina’s shoulder, and for a moment they sat facing each other, knees touching, hands still joined between them.
The distance was small. Too small for jokes. Too small for pretending.
Hoshina could see the exhaustion in Narumi’s eyes, but beneath it there was something brighter and more dangerous: hope, stripped of all its armor.
“You talk too much,” Hoshina whispered.
Narumi’s gaze dropped to his mouth. “You don’t talk enough.”
“Maybe I’m trying to balance things out.”
“Could you balance things out a little closer?”
Hoshina should have laughed.
Instead, he closed the distance.
The first kiss was brief and almost cautious, so unlike both of them that Hoshina nearly pulled away. It was barely more than the brush of Narumi’s mouth against his, a question asked so softly that Hoshina could have pretended not to hear it.
Narumi caught the back of his neck before he could retreat. His touch was warm and careful, just as careful as he had been with the pinky promise, and that gentleness sent a strange flutter through Hoshina’s chest. It felt ridiculous. Hoshina had faced monsters without blinking. He had stood in the path of blades, watched buildings come down, and walked away from danger with his pulse steady.
But Narumi was looking at him like this, waiting.
Hoshina kissed him again.
This time, Narumi answered.
The second kiss lasted longer. Long enough for Hoshina to feel the startled hitch in Narumi’s breath, long enough for the warmth of him to seep through the space between them. Hoshina’s stomach turned over—not unpleasantly, but with the dizzy, weightless sensation of missing a step on the stairs. Butterflies, he thought, absurdly. Actual butterflies, flapping themselves to pieces beneath his ribs.
Narumi tilted his head, and Hoshina followed without thinking. Their noses bumped. Narumi made a quiet, embarrassed sound against his mouth, and Hoshina felt a smile tug at the corner of his lips. The sound was so unlike Narumi’s usual confidence that it made something bright bloom inside him.
“Don’t laugh,” Narumi murmured.
“I’m not.”
“You are.”
“Maybe I like seeing you flustered.”
Narumi’s eyes opened, dark and startled. “You’re one to talk.”
Hoshina could feel the heat rising into his own face. “Shut up.”
Narumi smiled against his mouth, and the kiss turned soft again. He brushed his lips over Hoshina’s once, twice, as if he couldn’t quite bring himself to stop now that he had been allowed to begin. Each small kiss landed somewhere different—at the corner of Hoshina’s mouth, just beneath his lower lip, at the place where his breath caught.
The butterflies only grew worse.
All the tension between them seemed to collapse at once—not disappear, but change shape. Years of rivalry, every sharp remark and reckless challenge, every moment of standing too close after a mission, all of it gathered in the space between their mouths. Narumi kissed like he did everything else: intensely, as if hesitation had finally become unbearable. Hoshina met him with a steadier kind of hunger, one that had learned patience only because it had never been given permission to ask for more.
Narumi’s hand slid from the back of his neck to his jaw. His thumb brushed Hoshina’s cheek, tentative at first, then surer when Hoshina leaned into it. Hoshina’s fingers curled into the front of Narumi’s jacket, wrinkling the fabric and pulling him closer until there was no careful distance left between them.
When they paused for breath, they stayed close. Their foreheads touched, their noses brushing, and Narumi’s breath came warm and uneven against Hoshina’s lips.
Hoshina’s heart was beating far too hard.
Narumi noticed. Of course he noticed.
“Your heart’s going crazy,” he whispered.
“Yours too.”
“Yeah.” Narumi’s smile softened. “Good.”
Hoshina should have made another joke. Instead, he closed the remaining inch and kissed him once more, slow enough to feel every startled flutter, every careful answer, every moment Narumi chose to stay.
When they finally broke apart, Narumi stayed close enough that their foreheads touched.
“That was more than five minutes,” he murmured.
“Don’t ruin it.”
“I’m just saying.”
“You’re always just saying.”
Narumi smiled, breath warm against his lips. “You kissed me.”
“You’re observant.”
“You like me.”
Hoshina sighed, but there was no force behind it now. “You’re still annoying.”
“Yeah.”
“Selfish.”
“Probably.”
“Needy.”
“Definitely.”
Hoshina brushed his thumb beneath Narumi’s eye, wiping away the faint shadow of exhaustion as if that could fix anything. Narumi went quiet beneath the touch.
“Stay,” Hoshina said.
The word was soft enough to be mistaken for a request.
Narumi didn’t mistake it.
“For five minutes?”
Hoshina looked at him. “No.”
Something in Narumi’s face broke open—not dramatically, not like a victory, but like a locked room finally admitting light.
He leaned in and kissed Hoshina once more, gentler this time.
When the clock reached morning, neither of them had moved from the couch. The headquarters remained quiet around them, waiting for another day of ranks, missions, and the endless rivalry that made it easier to survive the things neither knew how to say.
For now, though, there was only Narumi’s hand in Hoshina’s, their shoulders pressed together, and the five minutes that had become something neither of them was ready to name.
Not yet.
But Hoshina stayed.
And this time, so did Narumi.
