Chapter Text

The gym air had clung to everything the way sweat did-sticky, stubborn, impossible to ignore.

Even after the final whistle had long since died, Aoba Johsai's volleyball court still sounded alive: sneakers whispering over varnished wood, a ball thudding somewhere in the back like a heartbeat that refused to calm down, metal chair legs scraping as someone dragged them into place for cleanup. The fluorescent lights overhead buzzed faintly, washing the turquoise practice shirts in a tired kind of brightness.

Y/N lingered in the corridor outside the clubrooms with her school bag hooked around her wrist, fingers worrying the edge of an envelope until the paper softened and warped. The glue tasted faintly bitter where she'd tested it earlier-one nervous lick, immediately regretted, like touching a hot kettle just to confirm it would burn.

Airi stood beside her, neat as always, uniform immaculate down to the crisp fold of her collar. Her ponytail sat low, secured with a bright scrunchie that looked almost obnoxious against the beige-and-blue of Seijoh's colors. She leaned her shoulder against the wall and watched the clubroom door like it owed her money.

"Your hands are going to crumple it," Airi murmured.

"It's paper," Y/N said, voice low. "It crumples."

Airi's eyes slid toward the envelope anyway. "Mmh."

That sound-soft, satisfied-came with the tiniest tilt of her head, like she'd just watched a predictable scene play out exactly as she'd written it.

Y/N shifted her weight, the tile floor cold through the thin soles of her indoor shoes. Down the corridor, the boys' voices rose and fell in the chaotic way they always did after practice. Oikawa's laugh carried the farthest-too loud, too bright, the kind of sound that made people turn their heads even when they didn't want to.

Y/N stared at the row of lockers lined up against the wall. Most of them were scuffed with use, dents and scratches like old bruises. The volleyball team's section sat closest to the clubroom door, the metal smelling faintly of dust and old deodorant and that sharp, clean sting of disinfectant the school used on everything.

She swallowed. Her throat tasted like lukewarm tea and nerves.

"It's not even a confession," she muttered, mostly to herself.

Airi's mouth twitched. "That's what makes it worse."

Y/N shot her a look.

Airi only smiled, slow and wicked. "If it was a confession, you could at least blame it on temporary insanity. But admiration? Sincerity? That's premeditated."

Y/N's grip tightened. The envelope gave a small, betrayed crunch.

From inside the clubroom, a shout-someone complaining about serves, someone else laughing. A ball slapped against a palm. Then the sliding door rattled, and footsteps approached.

Airi straightened instantly, posture casual in the way only she could manage. "Okay," she breathed, barely moving her lips. "Go."

Y/N's feet didn't move.

Airi nudged her with the side of her shoe. "Go."

Y/N exhaled through her nose and stepped forward. The lockers were close enough now that she could see the name labels-some neat, some half-peeled, some scribbled with marker. Her eyes found his without thinking.

IWAIZUMI HAJIME

The letters looked too plain for how much space they took up in her head.

She crouched, pretending to adjust her sock, and slid the envelope through the small gap in the locker door. The metal was cool against her knuckles. For a second, her fingers hovered there, stupidly reluctant, like the paper might crawl back out if she let go.

She didn't.

The envelope disappeared with a soft scrape.

Her heart kicked once, hard enough that she felt it in her wrist. She stood too quickly, dizzy for half a beat, and backed away.

Airi caught her elbow-quick, light, steadying. "Breathe," she murmured, like she was offering a mint.

Y/N forced air into her lungs. It tasted like floor polish and the faint tang of sweat lingering in the hallway.

The clubroom door slid open.

Four boys spilled out in a loose wave of noise and motion-Matsukawa first, tall and lazy-limbed, towel slung around his neck; Hanamaki beside him, hands in his pockets, eyes half-lidded like he'd been dragged out of a nap; Oikawa in the center of it all, already fixing his hair with one hand, grin flashing like a mirror; and Iwaizumi behind them, shoulders tense beneath his blazer, tie loosened, shirt partially untucked as if he'd wrestled practice into submission and lost anyway.

Y/N's eyes snagged on him immediately-on the way his jaw worked when he spoke, on the way he moved like he was always bracing against something.

Oikawa swung an arm wide, nearly smacking Hanamaki in the face. "Tell me you saw that last receive-absolutely gorgeous-"

"Your ego's going to need its own locker soon," Matsukawa said, dry.

Hanamaki's mouth pulled sideways. "It already does."

Oikawa clutched his chest theatrically. "You guys are so cruel to me, your beloved captain."

Iwaizumi's expression didn't change. He reached past Oikawa and shoved the sliding door closed with a flat palm. The sound cracked through the hallway, sharp enough that Y/N flinched.

Airi's fingers tightened briefly on Y/N's elbow. She didn't look away.

The four of them moved toward the lockers. Y/N and Airi stayed tucked into the shadowed corner near the stairwell, half-hidden by a bulletin board plastered with event flyers.

Y/N's mouth had gone dry.

Oikawa stopped at his locker and began preening at his reflection in the metal, like it was a faithful audience. Matsukawa leaned against his own locker with the ease of someone who didn't worry about being judged. Hanamaki rummaged for something-maybe his phone, maybe a snack-moving with minimal effort.

Iwaizumi stepped up to his locker.

He opened it.

For one suspended second, Y/N's whole body went still, every sense narrowing to that small rectangle of space. The fluorescent light struck the envelope inside like a spotlight.

Iwaizumi's eyes dropped to it. His brows twitched-only a fraction.

Then his shoulders tightened.

He made a sound under his breath that didn't carry far, but the irritation in it did. His hand came up, rough fingers pinching the envelope like it was something sticky he didn't want on his skin.

Y/N's pulse slid into her throat.

Iwaizumi didn't turn it over. Didn't glance at the back. Didn't look for a name that wasn't there.

He huffed once, short and sharp, and tore it cleanly down the middle.

The rip sounded louder than it should have.

Y/N's stomach dropped so hard it felt like stepping off a stair that wasn't there.

Iwaizumi tore it again-another quick, efficient motion-then flicked the pieces into the nearby trash can without even aiming carefully.

Paper hit plastic with a thin, final tap.

He shut his locker door.

Y/N stared at the trash can like it had swallowed something alive.

Airi's hand fell away from her elbow. When Y/N glanced sideways, Airi's expression had changed-still composed, but her eyes had sharpened, the way they did when someone crossed a line.

From inside the clubroom, another group laughed-first-years, probably, loud and oblivious. The scent of detergent drifted out, mingling with the sweaty dampness of uniforms hung to dry.

Oikawa continued talking, unaware. "And then Iwa-chan looked at me like that-like he wanted to murder me-"

"I always want to murder you," Iwaizumi said, flat.

Matsukawa snorted. "That's his resting state."

Hanamaki glanced toward the corner where Y/N stood, eyes sliding over the shadows without landing. He yawned. "Let's go. I'm hungry."

They moved down the hallway, their footsteps fading.

Y/N didn't realize she'd stopped breathing until Airi leaned in close enough that her hair brushed Y/N's cheek.

"That," Airi whispered, voice too quiet to be kind, "was spectacularly bad."

Y/N's fingers had gone numb. She flexed them, and the feeling came back in pins and needles.

"I don't-" Her voice cracked on the first attempt. She cleared her throat, tasting metal. "I don't care."

Airi stared at her.

Y/N lifted her chin, stubbornness like a shield. "I don't."

Airi's gaze flicked to the trash can. Then back to Y/N. "Mmh," she said again, softer this time-less satisfied, more... thoughtful. "Okay. Then you won't mind coming with me tonight."

Y/N blinked. "Tonight?"

Airi stepped back and pulled out her phone, already tapping. "Downtown. Lounge café. They're doing some stupid event. Anonymous messaging or whatever."

Y/N's laugh came out wrong, sharp at the edges. "Why would I go?"

Airi's thumbs paused. She looked up, eyes bright and merciless. "Because you're going to sit across from a vending machine and drink something overpriced while you remember this moment for the next ten years anyway. I'd rather you do it with me."

Y/N swallowed. Her throat still felt scraped raw, like she'd swallowed torn paper.

Airi's smile returned-smaller, meaner. "Also," she added, "if I run into Oikawa, I want to make it his problem."

Y/N's mouth twitched despite herself.

Airi's eyes narrowed, catching it. "There it is."

Y/N looked away, jaw tight.

Behind them, the hallway hummed with the school's evening quiet-the distant clunk of someone closing a classroom door, the faint whirr of a floor buffer somewhere downstairs. The world kept moving, indifferent.

Y/N stared at the trash can one last time, then turned and followed Airi toward the stairwell, the cold air brushing her face as they pushed through the exit.

Outside, the evening bit at her skin immediately. The air smelled like wet pavement and winter-dry trees, sharp enough to sting her lungs.

Her breath fogged in front of her like something she couldn't hold onto.

Downtown Sendai glowed the way it always did at night-neon signs reflecting off damp sidewalks, traffic hissing past in waves, the smell of fried food and exhaust and perfume mixing together until everything felt a little unreal.

The lounge café Airi dragged her into was warm enough to make Y/N's cheeks sting as the heat hit them. Low lights hung like lazy stars. Music thumped through hidden speakers, bass soft enough to sink into the ribs without rattling teeth. The air smelled like espresso, syrup, and something citrusy someone had sprayed in the corner to pretend sweat didn't exist.

A vending machine near the restroom hummed steadily, its lights harsh compared to the café's amber glow. Every time it whirred to life for someone's purchase, it sounded too loud-like a secret being announced.

Airi led them to a table near the back, away from the biggest cluster of students. She slid into her seat and set her bag down with deliberate neatness.

Y/N sat opposite her, hands curled around a menu she didn't want. The laminated plastic felt sticky under her fingertips.

Airi leaned forward, eyes scanning the room.

Y/N followed her gaze without meaning to.

And there they were, as if the universe had a cruel sense of timing.

Four tall boys squeezed around a table that looked too small for them-Oikawa sprawled like he owned the place, his blazer open, tie loosened, fingers already combing through his hair; Matsukawa leaning back, long legs stretched out, expression unreadable; Hanamaki staring at his phone with the detached focus of someone watching a slow train wreck; and Iwaizumi sitting rigidly, shoulders squared, jaw set, his hands around a glass of something dark like it needed to be restrained.

Even from here, Y/N could tell he was still carrying practice in his body. His posture held that leftover tension-like the court hadn't let go of him yet. His knuckles looked dry, roughened, the kind of hands that gripped a volleyball until it obeyed.

Airi's lips curled. "Oh, good."

Y/N's stomach tightened. "No."

Airi's eyes flashed. "Yes."

Y/N's fingers dug into the menu. "We can leave."

Airi reached out and tapped the menu's corner, pinning it to the table with one nail. "We could," she said lightly. "But then you'd go home and replay the ripping sound in your head until sunrise."

Y/N's mouth flattened.

Airi's gaze softened for a fraction-so brief it could've been imagined. Then the sharpness returned. "Order something," she said. "I'll handle the rest."

The waitress approached with a bright smile and explained the café's special event with rehearsed enthusiasm: anonymous table messaging through an app, paired tables, no names, no faces-just text and the choice to reveal at the end.

Airi downloaded it immediately.

Y/N watched her with a kind of numb fascination. "You're really doing this."

Airi's eyes didn't leave her screen. "Absolutely."

Y/N's phone sat on the table like a brick.

Airi's gaze flicked up. "Don't be boring."

Y/N exhaled slowly through her nose and pulled her phone out. The screen's cool glass grounded her for half a second. She downloaded the app.

Airi leaned back, satisfied. "There. Now we're both culpable."

Across the room, Oikawa's laughter lifted again, loud enough to draw glances. Two girls at a nearby table whispered to each other, eyes flicking over him like he was a display.

Y/N looked away before she could get pulled into it.

The app pinged.

You have been paired. Two users online.

Airi's eyebrows rose. She angled her phone just enough for Y/N to see.

On the other side of the pairing, a username appeared.

GrandKingTooru✨

Y/N stared at it.

Airi made a small sound-half laugh, half scoff. "There it is," she said, like she'd just found a predictable item on a scavenger hunt.

Y/N's lips parted. No sound came out.

The sting of the morning flickered back to life like a match struck too close to skin.

Airi's fingers flew over the keyboard.

Airball: GrandKingTooru✨ is genuinely the most embarrassing username I've ever seen.

A response popped up almost immediately.

GrandKingTooru✨: WOW. Hello to you too, mysterious beauty. Are you always this harsh?

Y/N watched the words appear and felt something sour twist in her stomach.

Airi's smile widened, pleased.

Y/N's thumbs hovered over her own keyboard. Her hands felt cold despite the café's heat.

Across the room, Hanamaki's shoulders shook once-like he'd just seen something funny on his screen. Matsukawa leaned in slightly, eyes narrowing in mild interest. Oikawa's face brightened, grin stretching as he typed with theatrical confidence.

Iwaizumi sat still, gaze on his phone, expression blank.

Airi typed again.

Airball: Do you introduce yourself like that in real life too?

Y/N added, before she could talk herself out of it-

Pumpkin: Or do women usually run away before you finish talking?

Across the room, Hanamaki bent forward abruptly, a wheeze of laughter escaping him. Matsukawa's mouth quirked. Oikawa's head snapped up, scanning the room like he could locate the insult by scent alone.

"What-?" Oikawa hissed, scandalized. "That's so mean!"

Matsukawa didn't look up from his phone. "It's accurate," he said, voice flat as a tabletop.

Oikawa clutched at his chest. "You're supposed to be on my side!"

Hanamaki wiped at his eyes, shoulders still shaking. "I'm on the side of comedy," he managed.

Airi watched them like they were a show she'd paid for.

Y/N's gaze, traitorous, drifted back to Iwaizumi.

He hadn't laughed. He hadn't even smirked. He just stared at his screen with a kind of wary stillness, like he was waiting for something to jump out and bite him.

The app pinged again.

GrandKingTooru✨: You two are definitely just jealous because you've never met someone as perfect as me.

Airi typed-

Airball: We've met mirrors. Same experience.

Hanamaki actually slapped the table across the room. Oikawa's voice rose, indignant. "These girls are evil!"

Iwaizumi finally spoke, low and rough. "Stop flirting."

Oikawa's head whipped toward him. "I'm not flirting. I'm defending myself."

"You're typing hearts," Iwaizumi said.

Oikawa glanced down. "They're sparkles."

Matsukawa's voice drifted in, lazy. "Same disease."

Y/N's fingers tightened around her phone.

A new message appeared-different username. Shorter. Plain.

User_4: You two always this mean to strangers?

Y/N stared at it.

Airi's eyes gleamed. She answered instantly.

Airball: Only the annoying ones.

Y/N's thumbs moved without permission, the words forming with the ease of a bruise being pressed.

Pumpkin: At least strangers usually read things before throwing them away.

The café's noise blurred at the edges.

Across the room, Iwaizumi's body went still in a way that had nothing to do with volleyball. His shoulders stopped moving. His thumb hovered above his phone like it had suddenly become heavier.

Hanamaki's laughter died mid-breath. "...Iwaizumi?"

Iwaizumi didn't look up.

Matsukawa's gaze shifted from his own phone to Iwaizumi's face, eyes narrowing slightly, the humor fading into something watchful.

Oikawa, oblivious, was still typing angrily at Airball. "You're both just intimidated by my charm-"

Hanamaki cut him off with a sharp elbow. "Shut up."

Oikawa blinked. "Ow-what-"

Hanamaki's eyes stayed on Iwaizumi. "Dude."

Iwaizumi's throat bobbed once. His jaw worked, like he was chewing on something hard.

On Y/N's screen, there was nothing. No typing indicator. No reply.

Airi's gaze slid sideways to Y/N, assessing. "Oh?" she murmured, voice barely audible over the music.

Y/N didn't answer. Her hands had started to shake, fine and infuriating.

The app pinged again-another message, still from User_4, directed only to Y/N's side.

User_4: What's that supposed to mean?

Y/N's pulse hammered against her fingertips.

Airi leaned in, voice like silk wrapped around a knife. "Say it."

Y/N's mouth opened. Nothing came.

Airi's eyes didn't blink. "Mmh," she said, soft and certain. "You're going to say it."

Y/N's thumb hovered. Then pressed.

Pumpkin: Honestly, I thought you were different from Oikawa.

Across the room, Iwaizumi's eyes flicked up from his screen for the first time, scanning-quick, instinctive, as if he might spot the sender in the crowd by sheer force of will.

His gaze swept past Y/N's table without landing. The low light and distance protected her.

But the movement alone made her stomach twist tighter.

Oikawa kept talking, voice rising with wounded pride. "Why is everyone attacking me tonight? I'm a delight!"

Matsukawa's eyes stayed on Iwaizumi. "Maybe the universe's finally correcting itself," he murmured.

Hanamaki's grin had vanished entirely.

Iwaizumi looked back down at his phone.

The typing indicator appeared.

It stopped.

Started again.

Stopped.

Y/N could practically feel him on the other end, the weight of his silence.

Her screen pinged.

User_4: Who is this?

The words were simple. They hit like a hand on a bruise.

Y/N's throat tightened. The café's warm air suddenly felt too thick to breathe.

Airi's hand slid across the table, fingers brushing Y/N's wrist-barely a touch, but steady. A reminder that she wasn't alone, even if she'd put herself in the line of fire.

Y/N swallowed and typed, each letter like stepping onto thin ice.

Pumpkin: I was the one who left the letter in your locker this morning.

Across the room, Iwaizumi's breath caught-visible even from a distance in the way his shoulders jerked, the way his hand tightened around his phone until his knuckles paled.

Oikawa was still mid-complaint. "Iwa-chan, back me up-tell them I'm charming-"

Iwaizumi didn't answer.

Oikawa frowned, finally noticing. "...Hajime?"

Hanamaki leaned closer to Iwaizumi. "Hey," he said, quieter. "You okay?"

Iwaizumi's eyes stayed on the screen, unblinking. His face had gone unreadable, like someone had shut a door.

Matsukawa's expression shifted-subtle, but real. His eyebrows lifted a fraction, the teasing ease draining away.

On Y/N's phone, the typing indicator didn't appear.

Seconds stretched.

The bass of the music thudded on, indifferent. A glass clinked somewhere behind the counter. The vending machine hummed like a held breath.

Y/N's fingers curled around the edge of her phone until it bit into her skin.

Then-another ping.

Pumpkin: The letter was for you.

Airi's nails pressed lightly into Y/N's wrist, grounding her as if she'd felt the tremor too.

Across the room, Iwaizumi's chest rose and fell once, too shallow. His eyes flickered-not quite panic, not quite disbelief, but something that made him look suddenly younger, caught off guard in a way he clearly hated.

Oikawa leaned forward, trying to see Iwaizumi's screen. "What is it? Are they flirting with you? Because I-"

Hanamaki shoved Oikawa back by the shoulder. "Stop," he hissed.

Oikawa blinked, offended. "What did I do?"

Matsukawa's voice came out low. "For once? Everything."

Y/N stared at her screen, thumb hovering.

She could stop. She could let it hang there, unresolved, a wound left open.

Instead, she typed the last line with hands that wouldn't stop shaking.

Pumpkin: And you tore it up without even reading it.

The message delivered.

The café didn't go quiet, not really. The music kept playing. People kept laughing. Plates clinked. Someone near the window took a photo of their drink.

But at Table 7, something shifted-like the air had been pulled tight.

Iwaizumi stared at his phone as if it had accused him out loud.

His throat moved. His mouth opened a fraction, then closed again. His shoulders sank by a millimeter, the tension rearranging itself into something heavier.

He remembered it all with sickening clarity-the envelope, the handwriting, the snap of irritation after a day of being used as a shield between Oikawa and his fanclub. The automatic motion of tearing paper, practiced from ripping open protein bar wrappers and tape and anything else that got in his way.

He'd barely even looked.

Now his gaze stayed fixed to the screen, as if staring hard enough could rewind time.

Hanamaki's hand hovered near his shoulder, uncertain.

Matsukawa watched him like he was trying to decide whether to speak or let him sink.

Oikawa, finally sensing that this wasn't about him, quieted-his grin fading, his eyes narrowing with confusion. "Iwa-chan," he said, softer than usual, "what's going on?"

Iwaizumi didn't answer him.

He didn't answer anyone.

His fingers finally moved-slow, stiff-toward the keyboard.

Across the room, Y/N watched the typing indicator appear on her screen.

It blinked.

Once.

Twice.

Then stopped.

Airi leaned back in her chair, eyes on Y/N's face instead of the phone, as if she'd been waiting for this exact moment. "Mmh," she murmured again, like a verdict.

Y/N's mouth tasted like coffee she hadn't drunk yet-bitter, burned.

The typing indicator returned.

Iwaizumi's thumb hovered.

His shoulders drew in slightly, like he was bracing for impact.

Y/N stared at the screen until her eyes stung.

The message didn't come.

Not yet.

On the other side of the room, Iwaizumi finally lifted his gaze-slowly, reluctantly-scanning the café again, more carefully this time, like he'd realized the person behind the words might be closer than he'd ever expected.

His eyes passed over tables, faces, flickers of movement in the low light.

Y/N's breath caught.

Airi, calm as a blade, reached for her drink and took a slow sip, never looking away from Iwaizumi's searching gaze.

And then the app pinged softly, insistent.

A new message from User_4 appeared at last.

User_4: Where are you sitting?

Y/N's fingers went cold.

Airi's smile sharpened into something almost gentle.

"Answer him," she said quietly, like she was offering Y/N a hand off the edge of a cliff.

Y/N stared across the room at Iwaizumi-at the set of his jaw, the way his grip clenched around his phone, the way his eyes kept moving like he was hunting for a mistake he could fix.

Her thumb hovered over the keyboard.
