Behind the Mask

The gym smelled like sweat and floor wax—the kind of familiar that usually got Atsumu into the zone. Today, it didn't stick. The squeak of shoes, the thud of volleyballs, his teammates shouting—it all felt muffled, like he was underwater. He sat on the bench near the wall, legs stretched out, a towel over his shoulders. Beside him, Osamu chugged water from a blue bottle, his Adam's apple bobbing.

The rest of the team scattered across the court. Hinata and Kageyama bickering near the net, voices carrying. Nishinoya doing push-ups with Tanaka counting over him, grunts filling the air. The gym was alive. But there was this thin, invisible wall separating Atsumu from all of it. Like watching everything through fogged glass.

His stomach churned. Had been churning for weeks now. That constant low-grade nausea he'd learned to ignore. He'd gotten good at ignoring a lot of things. The way his reflection in the gym mirror blurred when he tried to look at himself. Scrubbing his face raw in the shower, trying to wash off grime he imagined clinging to his skin. Checking his phone at two in the morning, thumb hovering over a search bar he never used, then stuffing it under his pillow and biting his lip so he wouldn't cry.

He started wearing makeup three weeks ago. Light concealer for the dark circles, tinted lip balm so his lips didn't look so pale. Nothing obvious—he told himself it was for the camera, for team photos, for matches that got broadcast. But really? He couldn't stand his own face anymore. He'd look in the mirror and see something that didn't feel like him. Something fat and ugly, with that heavy jaw and those broad shoulders that refused to shrink no matter how much he hated them.

And the clothes. He had a secret drawer at the bottom of his wardrobe, hidden under a pile of old jerseys. Inside: two skirts—one black pleated, one soft pink with flowers—and a sleeveless tube top, white with lace trim. Bought them online with a prepaid card and a fake name. Never worn any of them. He'd held them up against his body once, in the dark of his room, and the sight of his thick arms and wide hips against that delicate fabric made him sick. Shoved them back into the drawer. Hasn't touched them since.

But he wanted to wear them. God, he wanted to. Feel the air on his shoulders, the swish of a skirt around his thighs. He wanted to be pretty. Just once. Look in the mirror and see something that didn't make him want to cry.

"Oi, Samu." His voice came out rough. He cleared his throat.

Osamu lowered the water bottle. "What?"

Atsumu's heart hammered. His hands were clammy. He picked at a hangnail. "Can I ask you somethin'?"

Osamu raised an eyebrow. "You just did. You want seconds?"

"Shut up." Atsumu took a breath. The words piled up in his throat, thick and heavy. He'd been thinking about this all day. All week. He needed Osamu to tell him he wasn't crazy, that he wasn't as repulsive as he felt. Osamu was his twin. Two halves of the same whole. If anyone could see the truth, it was him.

"Samu…" Atsumu's voice dropped, almost a whisper. "Do you think I'm pretty?"

The question hung in the air. Osamu blinked, then a slow, incredulous grin spread across his face. That grin he always wore before a sarcastic remark. The one that meant he was about to say something stupid and call it a joke.

"Nahhh," Osamu said, drawing the word out. He nudged Atsumu's shoulder. "Never saw such an ugly creature in my whole life."

He meant it as a joke. Brotherly needling, the kind they'd done a thousand times. Atsumu had called him ugly at least a hundred times, and Osamu fired back with equal venom. Their way. Banter. Love disguised as insults.

But this time, it hit different.

Atsumu's face crumpled. Fast, like a dam breaking. His eyes welled up, and a choked sob escaped before he could stop it. He bent forward, elbows on his knees, pressing the heels of his hands into his eyes. His shoulders started shaking.

Osamu froze. The grin vanished. "Hey… Atsumu?"

Atsumu didn't answer. Just kept crying, ugly and raw. The kind of crying he'd been doing alone in his room for months. The kind he swore no one would ever see. He tried to muffle it, but too late. A few heads turned—Hinata's curious glance, Nishinoya's worried look. Osamu waved them off with an awkward gesture, mouthing "it's fine," though it clearly wasn't.

"Shit," Osamu muttered. He put a hand on Atsumu's shoulder, felt the tremors running through his twin's body. "Atsumu. I was joking, okay? I was just—"

"No, you weren't." Atsumu's voice was thick with tears. "You meant it. I know you meant it."

"I didn't! I swear, I didn't. You know I'm an ass. I say dumb stuff. I was just—c'mon, you know I don't think you're ugly. You're my brother."

"Yeah, and you know me better than anyone." Atsumu finally lifted his head. His face was blotchy, eyes red and swollen. Mascara—he'd forgotten to remove it after last night's crying session—smudged under his eyes, a blackish smear he tried to wipe with the back of his hand. "You should know I'm not okay."

Osamu's stomach dropped. He saw the mascara stain, and a flood of understanding hit him like a spike to the chest. He'd seen that before, in the bathroom mirror at home, when Atsumu thought he wasn't looking. Noticed the little things—the way Atsumu avoided reflective surfaces, the sudden shift in his eating habits, the late-night noise from the next room. But he pushed it aside. Told himself it was just stress, or a phase, or the same old rivalry acting up. He was an idiot.

"You're wearin' makeup," Osamu said softly. Not an accusation. A discovery.

Atsumu's face crumpled again. "I hate myself, Samu. I hate the way I look. I hate my face, my body, everything. I look in the mirror and I see a monster. I feel like I'm trapped in something I can't get out of." His voice broke. "I wanted to wear a skirt today. I bought a skirt. But I can't. I can't wear it because I look too ugly. I'd look like a freak."

Osamu's throat tightened. He didn't know what to say. Never good with words. Atsumu was the loud one, the one who talked and talked until people listened. Osamu was the quiet one, the one who listened and cooked and said the punchline after Atsumu set him up. But now, for the first time in his life, he needed to find the right words. And he didn't know if he could.

"You're not ugly," he said, voice hoarse. "You're beautiful, Atsumu. You're my twin. You're the same face I see in the mirror every day, and if you're ugly, then I'm ugly too."

"That's different," Atsumu sobbed. "You're—you're you. You're comfortable. I'm not."

Osamu pulled him into an awkward side hug, arm around Atsumu's shoulders. Atsumu leaned into him, body heaving with sobs. The gym's noise faded to a low hum. The team had gone quiet, their movements tentative, shooting glances toward the bench. But they stayed back. Respected the moment.

"I'm sorry," Osamu whispered. "I'm so sorry I said that. I didn't know. I should've known. I should've seen it."

"No one sees it," Atsumu said. "I hide it. I'm good at hiding."

"Not from me anymore." Osamu tightened his grip. "Alright? From now on, you don't hide from me. If you want to wear a skirt, you wear it. If you want to wear makeup, you wear it. I don't care what anyone thinks. You're my brother, and you're beautiful."

Atsumu let out a shaky breath. "I don't know if I can believe that."

"Then I'll keep telling you until you do." Osamu pulled back, looking him in the eye. "We'll figure this out. Together. Okay?"

Atsumu nodded weakly. He wiped his nose with his sleeve, smearing more makeup. "I'm a mess."

"Yeah, you are." Osamu gave a faint smile. "But so am I. That's what twins are for."

They sat there for a long time, shoulders touching, as the team resumed practice around them. Someone—maybe Kita, or Aran—turned the music back on, filling the gym with a beat that offered a semblance of normalcy. Hinata came by once and set down a fresh bottle of water for Atsumu, patted his shoulder once, then ran back to the court.

When the break ended, Osamu stood up and offered Atsumu a hand. "C'mon. You don't have to practice if you don't want, but I think it'll help."

Atsumu took his hand and stood. His eyes were still red, but there was something else in them now. Not hope, exactly. But the faintest flicker of light in the darkness.

"Okay," he said. "But I'm not takin' any of your shitty sets today."

Osamu snorted. "Yeah, right. You love my sets."

They walked back onto the court. And for the first time in weeks, Atsumu didn't feel quite so alone.
