Rhythm of the Heart

The gym at Inarizaki had never seen a practice like this. Fluorescent lights buzzed overhead, making everything look washed-out. The volleyball nets were shoved aside. In their place, random folding chairs formed a loose semicircle around a bedsheet someone had commandeered as a projector screen.

It was Suna’s idea, obviously. He strolled in with a portable projector under his arm, smirking.

“Captain’s sick,” he announced. “I say we take a personal day.”

The team went wild. Practice called off. Projector set up. Now eleven boys sprawled on chairs and floor, phones forgotten, watching a YouTube compilation of cats falling off furniture. Laughter rippled through the group.

Atsumu sat cross-legged on the floor, back against the bleachers, scrolling through his own phone with half-hearted interest. He’d been the only one wanting to practice. Not that he was a model student, but the court had a rhythm he could trust. This was chaos.

“What else we got?” Osamu asked from somewhere to his left, cracking open a soda.

“Karaoke fails,” Suna offered, already typing.

“Nah, we seen those,” one of the first-years said. “Find something weird.”

“Define weird,” Suna said flat.

“I dunno. Something old. Unexpected.”

Ginjima snorted. “You want me to dig up videos of us from middle school?”

“Please don’t,” growled an upperclassman.

Suna scrolled lazily, blue light reflecting off his glasses. He stopped. His thumb hovered. Then he tilted his head, a flicker of interest crossing his usually blank face.

“Okay,” he said slowly. “Found something.”

“Is it gonna haunt our dreams?” Osamu asked.

“Maybe. Depends on how you feel about sequins.”

Atsumu’s ears perked up. Something cold settled in his stomach.

“What is it?” Ginjima leaned forward.

Suna connected his phone to the projector. The room went dark. The sheet lit up. A video buffered. Then the screen filled with a blurry, low-res image.

A stage. Small, modest, draped in gold and turquoise fabric. A banner read DANCE STAR WINNER — 2012 REGIONAL FINALS.

Gasps of laughter from the team.

“Okay, what is this, a toddler talent show?”

“That font is ancient.”

Suna glanced over his shoulder, smirking. “Wait.”

The camera refocused. Out from the wings stepped a small figure, maybe four feet tall, wearing a turquoise salsa outfit covered in sequins. Ruffled sleeves, tight black pants, tiny dance shoes clicking on the stage.

The kid was about eight. Blond hair in an awkward bowl cut, slicked back with too much gel. His face was set in intense, almost aggressive concentration. He raised his arms, fingers snapping, and the music exploded.

Salsa. Fast. Brash. The kid moved with unsettling precision—hips swaying, feet sliding, spins with a flair that would’ve been cocky on an adult. On a child, it was surreal.

The team burst out laughing.

“Oh my god, this kid thinks he’s a star!”

“Look at those spins! He’s a human top!”

Osamu was wheezing, soda sloshing. “I can’t—I can’t breathe—”

Atsumu went cold. He stared at the screen. That tiny, glittering nightmare from his past. The gym tilted.

Because that child was him.

No. No, no, no.

“You know,” Suna said, “I was looking up ‘regional dance competitors Hyogo’ as a joke. For my aesthetic project. Found this.”

“I don’t remember saying we should watch that,” Atsumu said, voice too high.

“What’s wrong, ’Tsumu?” Osamu wiped his eyes, still grinning. “Scared you’re gonna see someone you know?”

The child on screen executed a perfect turn, then struck a pose—chin lifted, finger pointing to the ceiling. The audience applauded. The banner flashed: DANCE STAR WINNER — Atsumu Miya, Age 8.

The laughter stopped.

Silence. Everyone turned to Atsumu.

His face went red, then white, then red again. Heat crawled up his neck.

“Is that…?” Ginjima started.

“Can’t be,” Osamu said, his voice flat now. He stared at his twin. “That kid’s name is Atsumu Miya.”

“Names aren’t unique,” Atsumu snapped, strangled.

“There’s a banner that says ‘Atsumu Miya, Age 8.’”

“Banners lie.”

Suna paused the video, kid frozen mid-spin. “Should I play the part where the announcer says his name? Because they say it. Twice.”

Atsumu wanted to disappear. His throat was dry, heart pounding.

“That’s you?” one of the first-years asked, voice full of delight and shock.

“It’s not—”

“’Tsumu.” Osamu’s voice was quiet. Serious. “When were you a salsa dancer?”

The question hung in the air. The team watched him, waiting.

Atsumu took a breath. Another. The walls he’d built—setter, smartass, volleyball freak—were cracking.

He let out a long sigh. “Fine,” he muttered. “Yeah. That’s me.”

The gym erupted.

“No way!”

“How do you go from that to volleyball?!”

“You looked like a tiny peacock, Miya-san!”

“Shut up, all of you!” But it came out weak. He rubbed the back of his neck, not meeting anyone’s eyes. “It’s a long story. I don’t gotta explain myself.”

Osamu shifted to sit right in front of him, expression unreadable. “I’ve known you my whole life. How do you not tell me this?”

Atsumu’s jaw tightened. He looked at his brother—confusion and hurt in his eyes—and something twisted in his chest.

“‘Cause I didn’t wanna remember,” he said quietly. “But I guess it’s out now.”

The room fell quiet again, but different. Curious. Aran leaned forward, brow furrowed. “Tell us, Atsumu. If you want.”

Atsumu stared at his hands, at the calluses from years of setting, and let himself drift.

“When I was little,” he started, “my parents got divorced. Messy one. Lots of shouting, lots of lawyers. Osamu and I got split up.”

Osamu stiffened. “I don’t remember that.”

“You were four. I was four. You wouldn’t.” His voice was flat. “I went with Dad to Osaka. You stayed with Mom in Hyogo.”

The team exchanged glances. This wasn’t where they expected the story to go.

“Dad worked a lot. He didn’t know what to do with a kid. So he signed me up for stuff. Soccer, basketball, swimming. I quit all of them.” A small, bitter smile. “But one day, he took me to this dance studio to pick up his friend’s daughter. And I saw them. The dancers. They were so confident. Like they owned the world. And I wanted that.”

“So you took salsa lessons?” Suna asked, neutral.

“I took everything. Salsa, bachata, cha-cha, some ballroom. For three years, that was my life. School, practice, competitions. Dad would take me all over Kansai for these stupid little tournaments. And I was good. Really good.” He paused, throat tight. “I won regionals when I was eight. Placed third in nationals the next year.”

“So what happened?” Osamu’s voice was soft.

Atsumu’s eyes went distant. “Dad died when I was twelve. Heart attack. Sudden. I came home from practice and he was just… on the floor.”

No one spoke.

“So I moved in with Mom. With you,” he said, looking at Osamu. “And I told myself that was the past. I threw away my medals, my costumes, everything. I started volleyball because it was something new. Something that didn’t remind me of him.”

He met his brother’s gaze. “I never told you because I didn’t want to be that kid anymore. The one who danced. The one who lost his dad. I wanted to be just Atsumu. Volleyball Atsumu.”

Osamu said nothing. He reached out and punched his brother lightly on the shoulder.

The silence hung there until Ginjima said, cautiously, “So… can you still dance?”

Atsumu blinked. “What?”

“Can you still dance? Like, right now?”

The mood shifted. The team perked up, the tension gone.

“Yeah, Miya-san, show us!”

“Prove it wasn’t a fluke!”

“I wanna see you do that spin thing again!”

Embarrassment rose hot and prickly, but underneath, something small and reckless stirred.

“Fine,” he said, surprising himself. He stood up, brushing off his knees. “But I need a partner.”

The team went quiet. Atsumu looked around, his gaze landing on Aran. The tall first-year was lounging against a stack of mats, watching with an amused smile that faltered when he realized all eyes were on him.

“Me?” Aran pointed at himself.

“You’re tall. Got good balance. I can work with that.”

“Atsumu, I don’t know how to salsa.”

“Don’t gotta know. Just follow my lead.”

Aran looked at him, then at the team, then back. A flush crept up his neck. “This is weird.”

“It’s about to get weirder.” Atsumu grinned, sharp and hungry. “Get up.”

Aran got up.

The team scrambled to make space, pushing chairs aside. Someone—Suna, probably—cued up a song. A low, sultry beat flooded the gym, Latin rhythm thrumming through the floorboards.

Atsumu’s heart pounded, but it wasn’t fear anymore. Anticipation. Exhilaration. He felt like stepping onto a stage.

“Okay,” he said, voice dropping lower. “Just follow me.”

He stepped close to Aran, close enough to feel the heat off his body. He placed one hand on Aran’s shoulder—broad, solid—and took his other hand, guiding it to his own hip.

“Here. Hold here.”

Aran’s hand was huge, warm, trembling slightly. His fingers pressed into Atsumu’s side, tentative.

“Tighter,” Atsumu murmured. “I won’t break.”

Aran’s grip tightened.

The music built. Atsumu moved.

Slow at first—a step, a sway, a rotation of his hips that drew a sharp inhale from someone. He guided Aran through the basic steps, pulling him forward, pushing him back, their bodies finding a rhythm. Aran was stiff, clumsy, but Atsumu kept fluid, leading with confidence.

He tilted his head, met Aran’s eyes. “Loosen up. Feel the music in your bones.”

“I’m trying,” Aran said, strained.

“Try harder.”

Atsumu spun himself out, then back in, his chest pressing against Aran’s for a breathless second. He heard a low whistle from the team, felt eyes on him. And he loved it.

He dropped lower, rolling his hips in a slow figure-eight, gaze locked on Aran’s. The boy’s face was bright red, breathing uneven, but he didn’t look away. Couldn’t.

“Good,” Atsumu purred. “You’re learning.”

He turned, pressing his back against Aran’s chest, and moved—slow, teasing, grinding in a way that was absolutely inappropriate for a high school gym. The team erupted in shouts and laughter, but Atsumu blocked them out. He was in the zone, in the music, in the pure joy of performance.

He spun again, dropping into a low dip, arching backward against Aran’s arm. His hair brushed the floor. His eyes never left Aran’s.

Aran was breathing hard, pupils blown wide. His hand on Atsumu’s back was shaking.

Atsumu smiled, slow and wicked. “You okay there, partner?”

“Fine,” Aran croaked.

“Good. Because we’re not done.”

He pulled himself back up, stepped in close, and moved with increasing intensity—hips swaying, shoulders rolling, fingers dragging down his own chest before reaching out to trace along Aran’s jaw. He was closer than he’d ever been to anyone, sliding around Aran like water, circling him, teasing him, owning him.

The gym had gone quiet. Not confusion, but awe. Hunger.

Atsumu caught Suna’s gaze. The tall middle blocker was watching with something dark and appreciative in his hooded eyes. Osamu’s jaw was slack, soda forgotten. The other boys pressed closer, their earlier laughter replaced by a charged, heavy silence.

Atsumu felt powerful. Invincible. His embarrassment had burned away, leaving only the pure joy of being seen.

He ended the dance with a flourish—a spin, a dip, a final pose draped across Aran’s arms, chest heaving, triumphant grin.

For a second, no one moved.

Then the gym exploded. Clapping, shouting, wolf-whistles echoing off the walls. The team crowded around, clapping his back, demanding another song. Aran stood frozen, still holding him, face almost painfully red.

“Put me down, big guy,” Atsumu laughed, pushing lightly at his chest.

Aran set him down, cleared his throat, looked anywhere but at Atsumu. “That was… something.”

“That was amazing!” one of the first-years crowed. “Miya-san, you’re a legend!”

“I know,” Atsumu said, his voice lighter than it had been all day. He looked at his brother, who was watching with an expression he couldn’t quite read.

“‘Not bad, ’Tsumu,” Osamu said finally, a small smile tugging at his lips. “Not bad at all.”

Something warm spread in Atsumu’s chest. Validation. Pride. A sense of belonging that had nothing to do with volleyball.

“Okay, okay, encore!” someone shouted.

“I want to be his partner next time!”

“Get in line!”

The night dissolved into laughter and music, the team bonding over a secret they’d carry forever. Atsumu danced twice more, then three times, each more confident. He taught a few of the boys basic steps, watched them stumble and fall, laughed until his sides ached.

By the time they packed up the projector, the moon was high and the stars were out.

Atsumu lingered in the gym, leaning against a wall, watching his teammates file out with tired smiles and renewed energy. Osamu paused at the door, looking back.

“Coming?”

“In a minute.”

Osamu nodded. For a moment, they just looked at each other, sharing a smile that said everything.

Osamu left.

Atsumu stayed, breathing in the familiar scent of sweat and rubber, feeling the echoes of his movements in his bones. He pressed a hand to his chest, to the steady beat of his heart.

He wasn’t just a volleyball player. He wasn’t just a setter. He was a dancer. A showman. A boy who had lost his father and found himself again.

And tonight, he had shown them all.

The gym fell silent
