Work Text:
Jaehyun doesn’t collapse in a dramatic way.
It starts smaller than that.
They’re barely offstage, still close enough that the bass from the speakers leaks through the walls when the floor shifts. It tilts, slow and wrong, like someone grabbed the building and rotated it a few degrees to the left.
He stops walking.
At first, he thinks it’s adrenaline wearing off. Blood pressure drop, maybe. He blinks once, then again. The hallway stretches and narrows at the same time, the lights smearing slightly at the edges.
Then the spin hits.
Jaehyun reaches out automatically, fingers grazing the wall, but the wall doesn’t stay where it’s supposed to be. His hand misses. His shoulder follows, bumping into Sungho who turns just in time to catch the look on his face.
“Jaehyun?”
He tries to answer. The word makes it halfway to his mouth before nausea crawls up his throat instead. The floor pitches harder. His knees give out without warning, like someone unplugged them.
He doesn’t fall forward. He drops down.
Riwoo reacts first, he just barely manages to guide Jaehyun so his shoulder hits the floor instead of his head. Jaehyun’s vision fractures immediately, doubling, tripling. The ceiling spins like it’s been unhooked.
“Oh shit,” Riwoo says, sharp and unfiltered.
Taesan is suddenly there too, crouching, hands hovering uselessly because touching him won’t fix the problem and they all know it. Jaehyun curls instinctively, one arm pressed to the side of his head, jaw clenched tight.
The vertigo is total.
He can’t tell where down is anymore.
Every time he opens his eyes, the world rotates. Close them, and the spinning gets worse, like his inner ear is furious at being ignored. His breathing turns shallow, uneven and not panic, not yet, just his body trying to cope with conflicting signals.
Leehan swears under his breath. “He’s not faking. Don’t move him.”
A staff member drops to a knee nearby, already calling for medical. Another waves people away from the corridor, voice tight. The hallway that was loud seconds ago goes unnaturally quiet, like everyone’s afraid sound will make it worse.
Jaehyun hears his name a few times, but it sounds distant, underwater. He can’t focus on faces. He can feel the cold floor seeping through his costume, grounding and awful at the same time.
His stomach lurches.
He turns his head just enough before he gags, nothing coming up but saliva and a sharp, humiliating cough. Someone passes him a towel. He grips it like an anchor.
“Don’t sit him up,” the medic says, arriving breathless. “Just keep him still. Jaehyun, can you hear me?”
He nods once. Immediate regret. The world somersaults.
“Okay. Okay, don’t do that again,” the medic mutters. “Eyes closed if you can. Breathe.”
Taesan stays where he is, not touching, just there visible when Jaehyun cracks one eye open, which helps more than words. Sungho answers questions in clipped sentences. Woonhak looks pale, hovering a step back, hands clenched into fists like he’s trying not to shake.
They lay Jaehyun flat, jacket folded under his head. The spinning doesn’t stop, but it slows, enough that the nausea eases into something manageable. Sweat beads along his hairline, cold and sticky.
“This is vertigo,” the medic says quietly to the manager. “Could be dehydration, could be inner ear. He didn’t black out.”
Jaehyun hates how weak his voice sounds when he finally speaks. “I… can’t stand.”
“I know,” Taesan says immediately, sharp with certainty, like it’s a fact, not a failure.
They don’t try to get him up. No one tells him to push through it.
As they lift him onto the stretcher, carefully, the room tilts again, but less violently this time. Jaehyun keeps his eyes shut, focusing on breathing, on the steady pressure of the towel in his hands.
The panic stays external.
Staff moving fast. Members watching with tight expressions. Voices low and urgent.
Jaehyun himself is too busy trying not to throw up to feel anything else.
They move him to a quieter room near the medical station, away from the traffic and noise. The stretcher stops; the sudden lack of motion makes his stomach flip anyway.
Jaehyun keeps his eyes closed.
Someone dims the lights without asking. He notices because the pressure behind his eyes eases just a fraction.
“Okay,” the medic says, calmer now. “You’re safe. Still dizzy?”
Jaehyun nods. This time he doesn’t move his head, just a small motion of his hand, thumb brushing the towel. Talking feels like it’ll trigger another wave.
They don’t push him to speak.
Cold packs get placed along his neck and wrists. Water is offered, then immediately pulled back when he retches again, dry and sharp. The medic switches tactics, pressing a small alcohol swab near his nose instead.
Taesan sits on the floor, back against the wall, close enough that Jaehyun can feel someone there without being touched. Sungho stands by the door, arms crossed, eyes flicking between the medic and Jaehyun like he’s memorizing every instruction.
Riwoo keeps glancing at the clock. Calculating schedules, delays, what gets canceled. What doesn’t matter right now.
“Blood pressure’s low,” the medic murmurs. “Pulse is fast, but not dangerous.”
Jaehyun’s body feels wrong in a quiet way. Heavy. Disconnected. Like his head is floating a few inches above where it should be.
They prop him slightly on his side once the nausea eases. The spinning doesn’t stop, but it slows enough that the ceiling stops trying to flip over itself. He risks opening one eye.
Bad idea. The room immediately tilts.
He squeezes his eyes shut again, jaw tightening.
They give him time. Real time. Minutes stretch out without anyone rushing him, without cameras, without voices trying to fill the silence. A manager slips in, whispers with the medic, then leaves again.
Eventually, the medic tries again. “Jaehyun, can you wiggle your fingers for me?”
He does. Slowly. It feels like they belong to someone else.
“Good. Any numbness?”
“No.” His voice cracks a little, unused.
“Okay. We’re not standing you up yet.”
Thank god.
They help him sit slightly more upright only after the spinning settles into something dull and tolerable. Taesan shifts automatically, offering his shoulder, but doesn’t pull him and just lets Jaehyun lean when he needs to.
Woonhak finally speaks, quiet. “Hyung… does it still feel like you’re moving?”
“…yeah.”
“Okay,” Woonhak says, like that answer fits exactly what he expected.
Another bottle of water appears, this time with a straw. Jaehyun takes careful sips, pausing every few seconds. No one tells him to hurry.
When they finally help him stand—much later—it’s slow and awkward. The room sways, but doesn’t flip. His knees shake, but they hold. Two staff members hover close, ready to catch him if it goes wrong.
He doesn’t make it far. Just to a couch.
That’s enough.
The verdict is simple: observation, fluids, rest. No encore, no interviews, no pretending he’s fine.
As they settle him back down, jacket draped over his shoulders, Jaehyun exhales shakily.
By the time they get back to the hotel, it’s past midnight.
Jaehyun doesn’t remember the walk from the van to the elevator. He remembers the carpet pattern in the hallway because it wouldn’t stop shifting under his feet, and the way Taesan kept walking half a step slower than everyone else so Jaehyun could follow without thinking.
They get him into the room and that’s when the adrenaline finally drains.
He sits on the edge of the bed, shoulders slumped, staring at nothing. The vertigo isn’t violent anymore, just this low, sick pull, like the room might tilt if he blinks wrong.
A trash bin gets placed near his feet without a word.
Sungho kneels to untie Jaehyun’s shoes because bending down himself still feels risky. Jaehyun watches his hands move, neat and practiced, like this is something they’ve done a hundred times before even though it isn’t.
“Lights,” Riwoo says quietly.
Leehan dims them.
Jaehyun exhales. It comes out shaky despite his effort to keep it even.
“I’m okay,” he says automatically.
No one reacts. Like they collectively decided that sentence doesn’t count right now.
Taesan sits on the floor again, back against the bed this time.
Woonhak’s perched on the armchair, phone forgotten in his hand. He keeps replaying it in his head—the way Jaehyun’s steps had gone uneven, the split second where his eyes didn’t focus on anything.
“Hyung,” Woonhak says, hesitant. “Earlier… did you feel weird on stage already?”
Jaehyun thinks. Actually thinks, instead of brushing it off.
“…yeah,” he admits. “But I thought it was just lights.”
That answer lands heavier than anything dramatic could’ve.
Sungho presses his lips together. Riwoo looks away, jaw tight. Taesan’s fingers curl against the carpet.
“So you kept going,” Taesan says, not accusing. Just stating it.
Jaehyun nods once. Small. Careful.
There’s a stretch of silence where no one fills it with comfort lines or jokes. It’s the kind of quiet where everyone is recalculating something internally.
Eventually, Leehan speaks. “Next time you say something.”
Jaehyun huffs a weak laugh. “That’s not new advice.”
“I know,” Leehan says. “That’s why I’m repeating it.”
That gets a faint smile out of him. Gone as fast as it appears.
They help him change—slow movements, sitting breaks, everything deliberate.
When Jaehyun finally lies down, the room feels too big and too still. His body sinks into the mattress, exhaustion settling deep, bone-heavy.
The vertigo lingers like an echo. Every time he shifts, the world nudges sideways.
Taesan doesn’t ask. He just grabs a pillow and lies down on the floor beside the bed.
Sungho notices and, after a second, does the same on the other side.
Jaehyun cracks one eye open. “You don’t have to—”
“Sleep,” Sungho cuts in calmly.
That’s it. Conversation over.
The next part is quieter. Phones get checked, messages sent to staff. Schedules quietly rearranged. No one says it out loud, but everyone’s thinking the same thing: That could’ve gone so much worse.
Woonhak’s the one who finally admits it, voice barely above a whisper. “I thought he was gonna hit the floor.”
No one argues.
Jaehyun hears it anyway.
“…sorry,” he murmurs into the pillow.
Taesan answers immediately, eyes on the ceiling. “Stop apologizing.”
“I mean it.”
“I know,” Taesan says. “Still stop.”
Jaehyun goes quiet after that.
Sleep comes in fragments. In between, he hears murmurs—Sungho telling someone on the phone that Jaehyun’s stable, Riwoo reminding Woonhak to sleep too, Taesan and Leehan shifting when Jaehyun’s breathing changes.
At one point, the room spins again and Jaehyun groans softly before he can stop himself.
Instantly, Taesan’s hand is on the edge of the bed. Not grabbing. Just there.
“It’s okay,” Taesan says, low. “Don’t move.”
Jaehyun stays still. The spinning fades.
When he finally sleeps for real, it’s heavy and deep.
And in the dark, surrounded by quiet breathing and bodies that refused to leave him alone with it, the night finally lets go.
