The Walls Have Ears (and Twins)

The evening had settled into that hollow quiet you only get in shared apartments when everyone’s pretending to be busy. Osamu sat cross-legged on his bed, a half-empty bowl of rice crackers balanced on his knee, while Suna scrolled through his phone from the other end of the mattress. The fridge hummed. The sink dripped. That was it.

"We could watch something," Suna said without looking up.

"Don't wanna."

"You always say that."

"'Cause I always mean it."

Suna snorted. Osamu recognized that sound—the prelude to a comfortable silence, the kind that didn't need filling. They were good at that. No expectations. Just existing in the same room.

Then the noises started.

First a thump, heavy and deliberate, like someone dropped a dumbbell. Osamu's chopstick hand froze mid-reach. He looked at Suna, who raised an eyebrow but kept scrolling.

Another thump. Then a third, each with a low groan that was unmistakably Atsumu's. Osamu's jaw tightened.

"Don't," he muttered.

"I wasn't going to say anything."

"You were thinking it."

"Maybe." Suna smirked. "But I keep my thoughts to myself. Unlike some people."

Another groan filtered through the wall, higher, more theatrical. Osamu knew that sound. He'd heard it a thousand times on the court, when Atsumu missed a set by a hair and made sure everyone knew about his suffering. But this wasn't volleyball.

A wet, slick noise followed. The unmistakable sound of—no. Osamu refused to finish that thought.

"Could be music," Suna offered, deadpan. "Experimental performance art."

"Shut up."

"I'm just saying. He's very creative."

The bed in Atsumu's room started creaking. Rhythmic, steady, mocking the concept of privacy. Then a male voice—not Atsumu's, deeper—muttered something that made Osamu's ear turn red.

"Lil sis," Osamu growled, setting the rice crackers down too hard. "That idiot. That absolute idiot."

Suna finally looked up, eyes glinting. "You know, most people would just put on headphones."

"Most people don't have a twin who's—" Osamu gestured vaguely at the wall, face hot. "Who's doing that."

"Being an adult?"

"Being a reckless moron."

"Same thing, usually."

The noises escalated. The slick sounds got louder, wetter, punctuated by Atsumu's breathy moans—loud enough that Osamu could practically feel them through the drywall. The male voice added commentary, crude and self-satisfied, the kind of thing that belonged in a cheap porno, not in the apartment Osamu shared with his twin.

"He's not even in a relationship," Osamu said, voice dropping to a mutter. "Single for months. And he just—he picks up randoms off some app and lets them—" He stopped, ran a hand through his hair. "It's self-harm, is what it is."

Suna blinked. "That's... a take."

"It is. He's not enjoying it. He's punishing himself. Using sex like a weapon."

"Against who?"

"Me, apparently." Osamu's tone turned bitter. "Everything's been about getting at me since the fight."

The fight. Two weeks ago. The longest, ugliest one they'd ever had. Started over something stupid—leftover onigiri, though the real issue had been festering for years. Atsumu said Osamu always played it safe, stayed in his lane, never took risks. Osamu snapped back about Atsumu being selfish, attention-seeking, incapable of thinking about anyone but himself. They yelled until their throats were raw, and Atsumu slammed his door so hard the frame cracked.

They hadn't spoken since. Just silent glances in the hallway, cold shoulders at breakfast, a wall of ice Osamu didn't know how to break.

And now this.

The bed creaking reached a frantic pitch. Osamu buried his face in his hands. Suna watched him with the detached fascination of a nature documentarian.

"You could text him," Suna said. "Tell him to keep it down."

"Like that would do any good."

"Or you could bang on the wall. Assert dominance."

"I'm not doing that."

"Your call." Suna returned to his phone. "But the acoustics are really something. I'm getting a pretty clear picture."

"Stop."

"I've got a vivid imagination. That's all."

A loud, wet slap through the wall, followed by a guttural cry from Atsumu—pained, ecstatic, theatrical. Osamu flinched. The male voice grunted something that sounded like approval.

"He's doing this on purpose," Osamu said, voice tight. "He knows I can hear. He wants me to."

"Mission accomplished, I'd say."

"I'm going to kill him."

"You can't. He's your twin. You'd feel it."

"I'll take that risk."

The noises continued for another agonizing ten minutes, each creak and moan a fresh needle in Osamu's nerves. Suna offered running commentary that was less helpful and more entertaining—for him, at least. Compared the rhythm to a bad volleyball serve, the pitch of Atsumu's moans to a dying cat, the whole performance to "a train wreck in slow motion, except the train's on fire and also naked."

When it finally stopped, the silence that followed was almost worse. Heavy. Anticipatory. Osamu held his breath, waiting.

Footsteps. The front door clicked open, then shut. Osamu counted to ten, then got up and peered through the peephole. The hallway was empty, but he could still hear the elevator dinging.

He cracked the door open and stuck his head out. The visitor—a man in his late twenties, maybe, with an expensive haircut and a dazed expression—was waiting for the elevator. He looked like he'd been through a war. Shirt untucked, half the buttons done wrong, lips smeared with a glossy pink that matched the shade of—

"That's Atsumu's lip gloss," Osamu said flatly.

The man turned. His face was covered in kiss marks—cheek, jaw, neck, even his forehead. And something glistening in his hair. A suspiciously sticky substance Osamu chose not to identify.

"Uh," the man said. "Hi."

"Did you have fun?"

"I..." The man blinked slowly. "I think so? I'm not sure. That guy is... intense."

"He's my twin."

The man's eyes went wide. He stepped back, nearly tripping. "Oh. Oh, shit. Look, man, I didn't know he had—"

"Just go."

The man practically dove into the elevator, jamming the button.

Osamu stood there a moment, staring at the closed doors, then turned back. Suna had appeared behind him, phone held up like a reporter's mic.

"Breaking news," Suna said. "Local man survives encounter with Miya Atsumu. More at eleven."

"Shut up."

"You know you love the drama."

"I really don't."

Osamu walked past him, steps heavy, and stopped in front of Atsumu's door. He knocked.

No answer.

He knocked again, harder. "Atsumu. I know you're in there."

A long pause. Then Atsumu's voice, muffled and hoarse: "Go away."

"Not happening."

"I'm busy."

"Doing what? Reliving your greatest hits?"

"Fuck off, 'Samu."

Osamu turned the knob. Unlocked. He pushed the door open and stepped inside.

The room was a disaster. Clothes everywhere—Atsumu's, the visitor's, tangled on the floor. Sheets twisted into a knot at the foot of the bed, damp and wrinkled. Air thick with sweat and sex and something floral, probably the body spray Atsumu used to cover up the smell of cigarettes he didn't smoke. A lamp knocked over, shade bent.

And there was Atsumu.

Sitting on the edge of the bed in a pink silk robe that did a terrible job covering him. It hung open at the chest, revealing a constellation of hickeys and scratches trailing down his collarbone. Hair a mess, eyes heavy-lidded, a smear of something suspicious at the corner of his mouth.

He looked smug.

"Enjoy the show?" Atsumu asked, voice dripping with false cheer.

Osamu's jaw clenched. "What the hell is wrong with you?"

"Nothin's wrong with me. I'm havin' fun. You should try it sometime."

"Fun." Osamu gestured at the room. "This is your idea of fun? Picking up strangers and letting them treat you like a ragdoll?"

"Jealous?"

"Disgusted."

Atsumu's smile faltered for a fraction of a second before snapping back. "Don't pretend you care. You haven't talked to me in two weeks. Why start now?"

"Because you're making it impossible to ignore."

"Good." Atsumu stood, cinching the robe tighter. Deliberate, theatrical, like he was on stage. "Maybe if I'm loud enough, you'll actually see me."

"I see you just fine. I see a guy who's hurting himself because he doesn't know how to use his words."

"Words are overrated." Atsumu walked past him into the kitchen, grabbed a bottle of water from the fridge, and drank deeply. His throat worked, and Osamu could see the bruises—thumb-shaped and purple.

Something cracked in his chest.

"Remember two weeks ago?" Osamu said quietly.

Atsumu froze.

"Not the fight," Osamu continued. "Before that. When we played that practice match against the second-years. You set that perfect quick to me, and I missed it. And you said—"

"I said you'd never be as good as me."

"Yeah."

Atsumu set the water bottle down with a soft clink. His shoulders were rigid. "I didn't mean it."

"Then why did you say it?"

"Because I was angry." Atsumu's voice dropped. "Because you were looking at me like I was a disappointment. Like everything I do is just... noise."

"You were the one who started it."

"I know." Atsumu turned around. His eyes were shiny, but he wasn't crying. Not yet. "I know I started it. And I know I've been actin' like an ass. But you—you just shut down. You didn't even try to fight back. You just walked away and ignored me for two weeks, like I was nothin'."

"You were the one who said you didn't want to talk."

"Because I didn't know how! I don't know how to do this, 'Samu!" His voice cracked. "I don't know how to be normal. I don't know how to talk about feelin's without it turnin' into a fight. So I just—I just do stuff. I do stupid stuff. Because at least when I'm doin' stupid stuff, someone's lookin' at me."

Osamu stared at him. The anger was still there, simmering, but it was mixing with something else. Guilt. Sadness. The same old ache he'd been carrying since they were kids, watching his twin burn through the world like a comet, always too fast, too bright, too close to destruction.

"You don't have to do this," Osamu said softly.

"Then what do I do?" Atsumu's voice was raw. "Tell me. I'm beggin' you, tell me what to do, because I'm tired. I'm so tired of this."

The silence stretched. Osamu took a step forward. Then another. Stopped a foot away, close enough to see the faint tremor in his twin's lip.

"Talk to me," Osamu said. "That's all I ever wanted. Just talk to me. Don't shut me out."

"You shut me out first."

"I know. I'm sorry."

Atsumu's breath hitched. A single tear slipped down his cheek, and he wiped it away quickly, angrily. "I hate you."

"I know."

"You're so annoyin'."

"I know."

"And you're a hypocrite. You tell me to talk, but you never say anythin' either."

"I know." Osamu let out a shaky breath. "I'm working on it."

Atsumu sniffled. He looked smaller now, the theatrical bravado stripped away. Just a guy in a pink robe with a messy heart and a habit of making bad choices.

"I don't actually like doin' that," Atsumu said quietly. "With strangers. It makes me feel... empty. But it's the only time I feel anythin' at all."

Osamu's throat tightened. "Then find something else. Something that doesn't leave you covered in lipstick and regret."

"Like what?"

"Like... I don't know. Bake something. Annoy Suna. Pick a fight with me that doesn't involve actual damage."

Atsumu let out a wet laugh. "You'd let me win?"

"Maybe. If you asked nicely."

They stood there, the tension slowly unwinding. Osamu reached out and awkwardly patted Atsumu's shoulder. Atsumu leaned into it, just a little.

"I'm sorry," Atsumu mumbled.

"I know."

"For bein' a jerk."

"Forgiven."

"For doin' that stuff when you could hear."

Osamu shuddered. "I'm going to need therapy for that."

"Worth it."

"Shut up."

Atsumu pulled back, rubbing at his eyes with the heel of his palm. "I meant what I said, though. You are a hypocrite. You never tell me how you're feelin'. You just bottle it up and then explode."

Osamu sighed. "I know. I'm trying. It's not easy for me."

"It's not easy for me either."

"Then we'll figure it out together."

Atsumu stared at him for a long moment. Then he cracked a small, genuine smile—the first one Osamu had seen in weeks.

"You're still an ass," Atsumu said.

"Takes one to know one."

"Twins."

"Unfortunately."

They stood there, not hugging, but close. The silence was different now—warmer, more comfortable. Osamu could hear his own heartbeat, slow and steady, matching the rhythm of Atsumu's breathing.

A voice from the doorway broke the moment.

"So, are we good now?" Suna was leaning against the frame, a bag of chips in hand. "Because I went and bought snacks for the after-show, and I'd hate for them to go to waste."

Atsumu blinked. "Did you watch the whole thing?"

"I didn't need to watch. I could hear. And I have a very vivid imagination."

"You're a creep."

"I'm your favorite creep." Suna tossed the bag of chips at Atsumu, who caught it clumsily. "Now come on. The drama's over, and I'm starving."

Osamu snorted. "You just wanted free food."

"That, and the entertainment value was unmatched." Suna turned and walked back toward the living room, tossing over his shoulder: "Better than any show on TV. You two should have your own reality series."

Atsumu looked at Osamu, a flicker of humor in his eyes. "He's not wrong."

"Don't encourage him."

They followed Suna into the living room, the tension finally broken. Atsumu sat down on the couch, still in his pink robe, and started tearing into the bag of chips. Osamu settled next to him, their shoulders brushing.

"You need a shower," Osamu said.

"Later."

"You smell."

"So do you, but you don't see me complainin'."

"That's because I'm a saint."

"You're a nosy, overprotective, hypocritical saint who eavesdrops on his twin's sex life."

"Again, not my fault your walls are thin."

"Get better headphones."

"Get better taste in hookups."

They bickered for a while, the words losing their sting, turning into the familiar rhythm of sibling banter. Suna sat on the floor, scrolling through his phone, occasionally chiming in with a dry remark.

It wasn't perfect. They still had things to work through—the fight, the weeks of silence, the underlying issues that had been building for years. But for now, it was enough.

Osamu looked at his twin, chip crumbs on his robe, hair a mess, hickeys on his neck, and felt something warm and heavy in his chest.

"Lil sis," he muttered.

Atsumu threw a chip at him. "Shut up."

Osamu caught it in his mouth.

Suna looked up, deadpan. "You two are disgustingly codependent."

"You love it," Atsumu said.

"I tolerate it."

That meant love. That meant family. And for now, that was enough.
