Gate to the Unknown

The airport terminal was chaos and boredom all mashed together—announcements crackling overhead, suitcases thudding against tile, a hundred conversations blurring into static. Atsumu Miya sat in one of those hard plastic chairs near Gate 23, legs stretched out, ankle crossed over ankle, trying to look like he belonged in the middle of all this noise. He wasn't pulling it off.

His knee bounced. His fingers drummed against the cardboard cup of matcha latte he'd bought twenty minutes ago, the drink already lukewarm. He wasn't thirsty. Just needed something to hold.

"Relax," Osamu said from the seat beside him, not looking up from his phone. Scrolling through something—recipes, memes, weather forecast for Okinawa. With Osamu you could never tell. His twin had always been the calm one, the quiet one, the one who didn't feel like he was crawling out of his own skin every time they were in a crowd.

"I am relaxed," Atsumu snapped, too fast.

Osamu glanced at him. One eyebrow lifted. "Your knee's gonna fall off."

Atsumu stopped bouncing. Started again two seconds later.

Suna Rintarou sat on Atsumu's other side, leaning back with that usual half-lidded expression, earbuds in, watching the chaos like a cat observing a busy ant farm. He pulled one earbud out. "You two want anything from the shop? I'm gonna grab snacks."

"Onigiri," Osamu said immediately.

"They won't have onigiri in a duty-free shop, genius."

"Then find something."

Suna rolled his eyes, but he was already standing. He looked at Atsumu. "You?"

Atsumu shook his head. The motion felt jerky, uncoordinated. "I'm good."

"You've been holding that drink for forty minutes and haven't taken a sip."

"I'm savin' it."

Suna's gaze lingered a moment longer than comfortable. Then he shrugged and walked off toward the shops, hands in his pockets. Osamu stood too, stretching with a small groan.

"I'm gonna go with him," he said. "Need stuff for the flight."

Atsumu's chest tightened. "You're leavin'?"

"Just to the store. Five minutes." Osamu frowned. "You okay?"

"Yeah. Fine. Go."

Osamu hesitated. A brief thing, barely a breath of a pause, but Atsumu caught it. His twin knew him too well. But he didn't push, and that was worse, because it meant Atsumu's mask was still holding. He watched Osamu walk away, falling into step beside Suna, their figures disappearing around a corner past a row of vending machines.

And then Atsumu was alone.

The terminal was still full of people. Louder, even, as a flight to Seoul started boarding at the next gate. Families with toddlers. Businessmen in stiff suits. A group of teenage girls taking group photos near the window. Normal sounds. Normal people.

Atsumu's hands started to shake.

It came on like a tide. Not sudden—no, that would have been easier, a wave he could brace for. This was slow, insidious, a creeping cold that started in his chest and radiated outward. His heartbeat picked up. His palms went slick. The matcha cup crumpled slightly under his grip.

Stop it. Stop it. You're fine. He's coming back. He said five minutes.

But the thoughts didn't help. They never helped. The fear that lived at the base of his spine, the one he'd been carrying since he was fifteen years old, unspooled like a thread pulled loose. He's not coming back. Why would he? You're too much. You've always been too much. He finally realized it, and he left.

Atsumu sucked in a breath. It came out shallow. He tried again, and it hitched halfway down his throat.

The airport lights seemed brighter. Hotter. The announcements blurred into noise, and the noise blurred into pressure, and the pressure pushed down on his chest until he couldn't tell if he was breathing at all. He stood up abruptly, knocking his knee against the seat. The matcha cup slipped from his fingers and hit the floor, the lid popping off, beige liquid splashing across the tile.

Someone said, "Hey, you dropped—"

But their voice was far away. Underwater. Atsumu stumbled away from the seat, one hand braced against the nearest pillar, the other pressed flat to his sternum. His heart was trying to escape his ribcage. His vision was tunneling, dark at the edges, closing in like a camera aperture.

Breathe. Breathe, you idiot. BREATHE.

He couldn't.

His knees buckled. He caught himself, barely, sliding down until he was sitting on the floor, back against the pillar, legs drawn up. His chest heaved. Each breath was a knife, sharp and useless. Tears pricked at his eyes—not sadness, but panic, pure animal terror that had no target, no reason, no off switch.

He was vaguely aware of voices. A woman's, high and concerned: "Sir? Sir, are you okay?" A man's, lower: "Someone get medical." A child asking their mother why that man was crying.

Atsumu couldn't answer. Couldn't explain. Couldn't do anything but sit there and shake, his fingers digging into his own arms hard enough to leave crescents, his mind spiraling down a hole that had no bottom.

This is it. This is when everyone sees. This is when they know how broken you are.

And through the panic, through the static and the suffocating fear, one thought surfaced with crystalline clarity:

Osamu left. He left because you're too much. He's not coming back.

The sob that tore out of Atsumu's throat was ugly, raw, the sound of something breaking that had been fractured for a long time.

---

The first time Atsumu had a panic attack, he was fifteen.

Second day of a three-day volleyball camp in Hyogo. Twelve teams. Two hundred and fifty boys. All talented, all hungry, all chasing the same dream. Atsumu had been excited when their coach announced the camp. Thrilled. His first time representing their middle school outside of regular tournaments, his first chance to prove he wasn't just good—he was great.

Osamu had been rooming with him, same as always. But on the second night, a mix-up with sleeping assignments. Two boys from another school had to be moved into their room, and Osamu was relocated to a different floor to make space.

"I'll be two floors down," Osamu had said, already halfway out the door, duffel bag slung over his shoulder. "It's fine. We'll see each other at breakfast."

Atsumu had nodded. Smiled. Said, "Yeah, sure, whatever."

The moment the door clicked shut, the room got too small.

He sat on the edge of his futon and stared at the wall, and the silence pressed in like a living thing. He had roommates, strangers with unfamiliar faces and unfamiliar voices, but they weren't Osamu. They weren't the person he'd shared a womb with, a bedroom with, a life with. They weren't the half of him that made him feel whole.

His heart started racing. His palms got sweaty. He tried to breathe and couldn't.

He spent the night in the bathroom, sitting on the floor of a cold stall, back against the toilet, shaking so hard his teeth chattered. He didn't sleep. By morning, he'd convinced himself it was a fluke, a one-time thing. It had never happened before, so it would never happen again.

He was wrong.

It happened again at a training camp his second year of high school, when Osamu had to leave early for a family obligation. At a restaurant, when Osamu got up to use the restroom and was gone too long. At the airport the first time they flew to Tokyo for a nationals qualifier, and Atsumu locked himself in a bathroom stall until his hands stopped shaking.

He never told anyone. Not the coach. Not their parents. Not Osamu.

Especially not Osamu.

Because if Osamu knew, Osamu would worry. And if Osamu worried, he would never leave Atsumu's side, and that was exactly what Atsumu wanted, and that was exactly why he couldn't tell him. The dependency was already too deep, too tangled, too shameful. Atsumu was supposed to be strong. Confident. The loud, brash setter who could command a court and make everyone around him better. Not the twin who fell apart when his brother went to buy snacks.

He hid it. He mastered the mask. For years, it worked.

But masks always crack, eventually.

---

"Sir? Sir, can you hear me?"

Atsumu blinked. The world swam back into focus in fragments: fluorescent lights, a clipboard, a pair of kind eyes framed by wire-rimmed glasses. A woman in a blue uniform knelt in front of him, a medical badge clipped to her pocket. She was holding his wrist, checking his pulse.

"You're having a panic attack," she said, voice calm and practiced. "My name is Mika. I'm a nurse. I'm going to help you breathe, okay? Can you look at me?"

Atsumu's breath hitched. He tried to nod. It came out as a twitch.

"Good. That's good. I need you to breathe with me. In... and out... In... and out..."

He tried. He really tried. But his lungs wouldn't cooperate, and the tears wouldn't stop, and there was a small crowd gathered now, a semicircle of strangers watching him fall apart, and the shame was almost as suffocating as the fear.

Stop staring. Stop looking at me. Go away. Go away—

"Atsumu!"

The voice cut through the static like a blade.

Atsumu's head snapped up. Osamu was pushing through the crowd, Suna right behind him. His twin's face was pale, eyes wide, mouth set in a hard line that didn't quite hide the tremor in his jaw. He dropped to his knees in front of Atsumu, careless of the spilled matcha soaking into his jeans.

"Atsumu. Hey. I'm here. I'm here."

Atsumu grabbed for him. His fingers latched onto Osamu's sleeve, gripping so hard his knuckles went white. A sob escaped him, high and broken, and he pressed his forehead against his twin's shoulder, hiding his face from the strangers, from the lights, from everything.

"I got you," Osamu said, and his voice was rough, his hands coming up to grip Atsumu's shoulders. "I got you. Breathe. Just breathe."

The nurse—Mika—was still there, guiding his breathing, counting seconds. Someone handed Osamu a paper bag. He held it to Atsumu's lips.

"In through your nose, Samu. Come on. You can do it."

Atsumu breathed. The paper bag crumpled. He breathed again. The edges of his vision started to lighten, the tunnel widening, color returning to the world in slow, reluctant pulses.

It took ten minutes. Maybe longer. Time had lost all meaning.

When Atsumu finally lifted his head, his face was blotchy, his eyes red, and he felt hollowed out, scraped clean. The crowd had dispersed. The nurse was talking to someone in a uniform, probably airport security, explaining that no, this wasn't a medical emergency, just a panic attack, nothing to see here.

Nothing to see here. Atsumu almost laughed. It came out as a wet exhale.

Osamu was still kneeling in front of him. His jeans were stained. His hands were steady, but his eyes—his eyes were terrified. Atsumu had never seen that look on his twin's face before, and it made something cold settle in his gut.

"What the hell was that?" Osamu asked, quiet, so quiet Atsumu barely heard him.

"Panic attack," Atsumu said, voice raspy and thin. "Happens sometimes."

"Sometimes?"

"Osamu." Suna's voice cut in, low and warning. "Not here."

Osamu's jaw tightened. He looked around—at the gate, at the lingering stares, at the nurse now approaching with a small oxygen tank—and swallowed whatever he'd been about to say.

The nurse crouched down again. "We'd like to get you to the medical room, just for a quick check. Make sure your oxygen levels are stable. Can you stand?"

Atsumu nodded. He didn't trust his voice.

He tried to stand. His legs buckled. Osamu caught him, one arm sliding around his waist, steady and firm.

"I've got you," Osamu said again, and Atsumu leaned into him, too tired to feel shame anymore.

They made it three steps before the nurse's radio crackled. "Medical team to Gate 23, patient is ambulatory, escorting to—"

Atsumu stopped.

The nurse looked at him. "Sir?"

But Atsumu wasn't looking at her. He was looking at Osamu's face. His twin's gaze had dropped, fixed on something, his expression frozen in a way that made Atsumu's blood run cold.

Osamu's arm tightened around his waist. "Atsumu."

The word was barely a whisper. Heavy. Wrong.

"What?" Atsumu asked, but he already knew. He could feel it, the way his shirt had ridden up during the panic—the stretch of fabric across a belly that had once been flat and was now, unmistakably, not.

"When were you gonna tell me you're pregnant?"

The world stopped.

Atsumu felt like he was falling again, even though he was standing still. The terminal noise faded to a dull roar, the lights dimmed, and all he could see was Osamu's face—the shock, the hurt, the betrayal.

"Osamu," Suna said sharply, "not here."

But Osamu wasn't listening. He was staring at Atsumu, his brown eyes searching, desperate, demanding.

"Atsumu. Answer me."

Atsumu's lips parted. No sound came out.

The nurse, perceptive and professional, stepped in. "Let's get him to the medical room first. We can discuss everything there."

Osamu didn't move. Suna put a hand on his shoulder, and something passed between them—a look, a wordless negotiation. Osamu's shoulders dropped. He nodded, once, curt.

"Fine."

They walked. Atsumu's legs moved, but he wasn't piloting them. He was a passenger in his own body, floating somewhere above the tile floors and the fluorescent lights and the weight of the secret he had carried for four months, alone.

---

The medical room was small, sterile, and cold. Atsumu sat on an examination bed, an oxygen mask over his face, his hands folded in his lap. His fingers were still shaking. Not as badly as before, but enough that he could see the tremor when he looked down.

Osamu stood by the door, arms crossed, shoulders rigid. Suna leaned against the counter, giving them space but staying close enough to intervene if things went sideways.

The nurse had checked Atsumu's vitals, confirmed his oxygen saturation was back to normal, and asked if he needed anything else. He'd shaken his head. She'd left, closing the door behind her.

The silence stretched.

Osamu broke it first. "How far along?"

Atsumu closed his eyes. "Four months."

"Four months."

"I know how long it's been, Osamu."

"Does anyone else know?"

"No."

"Not even—"

"No one."

Osamu pushed off from the door, pacing a tight line across the small room. Three steps one way. Three steps back. His hands were clenched at his sides. "How? Who?"

Atsumu's breath hitched behind the mask. He pulled it down, letting it hang around his neck. "Does it matter?"

"It matters to me."

Atsumu looked at his hands. They were pale, the veins visible beneath the skin. He remembered the night, the alley behind the convenience store, the cold concrete biting through his jacket. He remembered the hands on him, the weight, the pain. He remembered thinking, This can't be happening. This isn't real.

He'd walked home after. Taken a shower. Gone to bed. And the next morning, he'd pretended it didn't happen, because pretending was easier than telling the truth.

"I don't know who," he said, voice flat, empty. "I don't know his name. I didn't get a good look at his face."

The room went still.

Osamu stopped pacing. His face drained of color, all of it, leaving him pale as paper. "Atsumu."

"Four months ago. I was walkin' back from the convenience store. Late. Took a shortcut through an alley." He swallowed. "I'm not gonna tell you the details. You don't need to hear that."

Osamu's mouth opened. Closed. Opened again. No words came out.

Suna moved. He crossed the room, slow, deliberate, and sat down on the bed beside Atsumu. Not touching him. Just... there.

"You're not going through this alone anymore," Suna said.

It wasn't a question.

Atsumu's eyes burned. He blinked, and a tear slipped free, trailing down his cheek. He wiped it away quickly, angrily.

"I was gonna tell you," he said, looking at Osamu. "I was. I just... I didn't know how. And the longer I waited, the harder it got."

Osamu's voice cracked. "You went through that alone."

"I didn't want you to look at me different."

"I'm lookin' at you the same."

"You're not." Atsumu laughed, bitter and broken. "You're lookin' at me like I'm glass. I can see it, Samu. I can always see it."

Osamu crossed the room in three strides. He dropped to his knees in front of the bed, just like he had at the gate, and took Atsumu's hands in his. His fingers were cold. His grip was firm.

"I'm sorry," he said. "I'm sorry I wasn't there. I'm sorry I didn't notice. I'm sorry I left you alone at the gate."

Atsumu's composure cracked. A sob escaped him, raw and ragged. "I hate this. I hate that I can't even be alone for five minutes without fallin' apart. I hate that I need you so much, it hurts."

"I don't care," Osamu said fiercely. "You can need me. I'm your brother. I'm here."

"This isn't your burden to carry."

"You're not a burden." Osamu squeezed his hands. "You're my twin. My other half. And I'm not gonna let you carry this alone anymore. The pregnancy, the trauma, the panic attacks—none of it. We're gonna deal with it together."

Atsumu closed his eyes. The tears kept coming, silent and steady. He leaned forward, letting his forehead rest against Osamu's.

"I'm scared," he whispered.

"I know." Osamu's voice broke. "I know. But I'm here. And I'm not goin' anywhere."

Suna stood, pulling out his phone. "I'll call the airline. Cancel the trip."

"You don't have to," Atsumu said. "You guys should still go. I'll be fine—"

"No," Osamu said. "We're goin' home. All three of us."

Atsumu opened his mouth to argue, but Suna was already stepping out of the room, the door clicking shut behind him.

Osamu stayed on his knees, still holding Atsumu's hands. "I meant it, Samu. I'm not goin' anywhere."

Atsumu looked at him. At the face that was his face, but different. At the brother who had been there for every scraped knee, every failed serve, every victory and defeat. At the person who had held him together his entire life without even knowing it.

"What do I do now?" Atsumu asked, and his voice was small, the voice of a child, a fifteen-year-old boy hiding in a bathroom stall.

Osamu's hand came up, gentle, cupping the back of Atsumu's head. He pressed a kiss to his twin's forehead, the way their mother used to do when they were small.

"Now," he said, "we go home. We find you a doctor. We get you help. And we take it one day at a time."

Atsumu nodded. He didn't have the strength for more.

Osamu helped him stand. Steadying him, anchoring him, the way he'd always done, the way he'd always do.

They walked out of the medical room together.

---

The car ride home was quiet. Suna drove. Osamu sat in the back with Atsumu, their shoulders touching, his hand resting over Atsumu's on the seat between them. Atsumu stared out the window, watching the highway lights blur past, his reflection ghostly in the glass.

Four months.

He'd spent four months hiding. Four months pretending. Four months carrying a secret that was growing inside him, literally and figuratively. A secret that had nearly destroyed him in an airport terminal, surrounded by strangers.

But now it was out. Osamu knew. Suna knew. And the world hadn't ended.

He still felt fragile. Unraveled. Like a sweater pulled loose by a single thread, everything unspooling. But Osamu's hand was warm, solid, real.

"Is it a boy or a girl?" Osamu asked quietly.

Atsumu's lips twitched. Almost a smile. "I don't know. They offered to tell me at the ultrasound, but I said no."

"You don't want to know?"

"I don't know what I want." Atsumu paused. "I haven't let myself think about any of it. What it means. What comes after. I've just been... existing."

Osamu nodded, slow. "That's okay. You don't have to have it all figured out tonight. Or tomorrow. Or next month."

"But you'll stay?"

"Until you tell me to leave."

Atsumu turned his head, resting his cheek against the cool glass. "I won't ever tell you that."

Osamu's grip tightened. "Good."

Outside, the highway lights continued to blur past. The city faded into suburbs, the suburbs into quiet streets. Home was getting closer.

Atsumu closed his eyes.

He didn't sleep. But for the first time in four months, he let himself breathe.

---

The hospital room was small, private, and quiet. Atsumu sat propped up against pillows, an IV drip in his arm—fluids and nutrients, the doctor said, to make sure both he and the baby were stable. He looked smaller in the hospital gown, shoulders hunched, hair messy and unwashed.

Osamu sat in a chair pulled close to the bed, elbows resting on the mattress, chin propped on his folded arms. He hadn't left since they'd checked in.

Suna was in the hallway, talking to the nurse about visiting hours and meal schedules, handling the logistics so Osamu didn't have to.

"You should go home," Atsumu said. "Get some real sleep."

"I'll sleep when you do."

"I'm in a hospital, Samu. I'm not exactly comfortable."

Osamu's mouth quirked. "Fair."

A moment of silence. Then Atsumu spoke again, voice soft, uncertain.

"Do you think I'm gonna be a good parent?"

Osamu looked at him. Really looked. At the shadows under his eyes, the tremor in his hands, the vulnerability he rarely let anyone see.

"I think," Osamu said slowly, "you're gonna be scared. And you're gonna make mistakes. And you're gonna have bad days. But I also think you're gonna love that kid more than anything in the world, because that's who you are, Atsumu. You love hard. You fight hard. And you don't quit."

Atsumu's eyes glistened. "I don't deserve you."

"You're my twin. You don't have to deserve me. I just am."

Atsumu let out a shaky breath. He reached out, and Osamu met him halfway, their fingers intertwining.

They sat like that, together, as the night deepened and the hospital settled into its quiet rhythm. Tomorrow would bring hard conversations. Doctors. Counselors. Decisions about the future, about the baby, about what came after.

But tonight, there was this.

Osamu holding Atsumu's hand.

Atsumu letting him.

And a new beginning, born from the wreckage of something old, waiting for them on the other side of the dark.
