Onigiri and Promises

The Miya household used to be loud. Growing up, it was volleyballs thudding in the backyard, their dad’s bark of a laugh, the constant bickering between twins that their mom would break up with a tired sigh and a plate of onigiri. Now the silence was the loudest thing in the house. It hung in corners, settled into the tatami mats, pressed down on Osamu’s shoulders every time he walked through the front door.

Two years since their father died. Two years since Osamu got named alpha of the pack—a title that felt less like a birthright and more like a lead weight chained to his throat. He was eighteen, fresh out of high school. Atsumu chased his volleyball dreams to the MSBY Black Jackals, but Osamu stayed behind, opened a small onigiri shop in the city. He told himself he was being practical. Told himself someone had to keep an eye on their mom, on the house. But the truth was simpler and uglier: he was hiding.

He didn’t want to be alpha. Didn’t want the responsibility of pack decisions, territorial disputes, making sure his omega brother was safe. Their beta mother—quiet, with steel in her spine—stepped into the gap without a word. She handled pack finances, mediated alliances, made sure Atsumu’s suppressants got refilled on time. Osamu let her. Told himself she was stronger. Told himself it was fine.

It wasn’t fine.

Afternoon sun slanted through the kitchen windows, casting long rectangles of light across worn wooden floors. Osamu stood at the counter rolling rice balls with mechanical precision. His fingers knew the moves by heart—gentle press, careful shaping, light dusting of salt. Halfway through his third tray when the front door slid open with that familiar, forceful rattle.

“Osamu? You here?”

Atsumu’s voice cut through the quiet like a blade. Sharp. Demanding. Osamu didn’t look up. “Kitchen.”

He heard sneakers thudding off, the impatient mutter of someone who never kept his shoes neat. Then footsteps—faster than they should’ve been—and Atsumu appeared in the doorway. Still in his Black Jackals track jacket, hair damp from a post-practice shower. His cheeks were flushed, but not from exertion. There was a tightness around his eyes Osamu recognized but chose to ignore.

“Oi,” Atsumu said. “I need to talk to ya.”

“Rice ain’t gonna roll itself,” Osamu replied, pressing another ball into shape. “Talk.”

“No. Not like this.” Atsumu stepped closer and, with a deliberate swipe, knocked the tray of finished onigiri aside. They tumbled across the counter, one falling to the floor with a soft wet thud. “I mean really talk, Osamu. Sit down.”

Osamu’s jaw tightened. He set down the rice paddle and finally looked at his brother. Atsumu’s eyes were red-rimmed, his scent sharp with anxiety underneath the usual omega sweetness of sandalwood and honey. That was new. Atsumu never let his scent slip. Too proud, too guarded.

“What’s wrong?” Osamu asked, voice flatter than he meant.

“Just sit down.”

They moved to the living room. The kotatsu was still set up from winter, though it was well into spring now. Atsumu sat across from Osamu, legs folded, fingers fidgeting with the hem of his jacket. Osamu watched him, waiting. He could feel the alpha instincts stirring beneath his carefully maintained apathy—a low, protective growl trying to claw its way up his throat. He swallowed it.

Atsumu took a breath. Then he pulled a folded piece of paper from his jacket pocket and laid it flat on the table. A form of some kind. Osamu caught the words “Medical Consent” and “Omega Reproductive Health” before Atsumu pushed it toward him.

“I need ya to sign this,” Atsumu said.

Osamu’s eyes scanned it. Birth control prescription request. Requires signature of designated pack alpha or legal guardian. The words landed like a punch to the gut. “What is this?”

“It’s a birth control prescription,” Atsumu said flatly. “I’m gettin’ on the pill. But the clinic says since I’m still technically under pack jurisdiction and not mated, I need your signature. Yer the alpha.”

The word alpha felt like an accusation. Osamu stared at the paper, at the blank line waiting for his name. His first instinct was to deflect. “Why can’t Mom sign it? She handles all that stuff.”

Atsumu’s lips pressed into a thin line. “Because she’s a beta. The form specifically says alpha or mate. And before ya say it, no, I’m not gonna ask some random alpha in the pack. Yer my brother. It has to be you.”

Osamu’s fingers twitched. He didn’t reach for the pen. “Why do ya need birth control?”

“Why do ya think?” Atsumu’s voice rose, a crack of frustration breaking through. “I’m an omega. I’m a professional athlete. I travel. I have a life. I’m not gonna let some heat cycle screw everything up, and I’m definitely not gonna get pregnant before I’m ready.” He crossed his arms, his scent flaring defensive. “It’s basic precaution. Nothin’ unusual.”

“Ya haven’t said anythin’ about this before.”

“Because ya haven’t asked.” Atsumu’s glare was sharp, but there was hurt beneath it. “When’s the last time ya actually asked me anythin’, Osamu? When’s the last time ya gave a damn about what I’m doin’?”

Osamu looked away. He didn’t have an answer. He reached for the pen, then stopped. The alpha in him was screaming—possessive, protective rage that had nothing to do with logic. His omega brother. His pack. Someone wanted to touch Atsumu. Someone already had.

“Are ya sexually active?” The question came out rough, almost a growl. “Who with?”

Atsumu’s cheeks flushed, but he didn’t back down. “That’s none of yer business.”

“It is my business if I’m signin’ this form.”

“Fine.” Atsumu’s jaw set. He looked down at his hands, then back up, meeting Osamu’s eyes. “I have a boyfriend. We’ve been together for six months. His name’s Kiyoomi. Sakusa Kiyoomi. He’s on the team. He’s an alpha.”

The name hit like a spike to the floor. Sakusa Kiyoomi. Osamu knew of him—everyone in the volleyball world did. Talented. Intense. Fiercely independent. An alpha from a prominent family. The image of Atsumu with him, with anyone, sent a hot surge of jealousy and anger through Osamu’s chest. Irrational. Primal. He hated it.

“Six months?” Osamu’s voice was low, dangerous. “Ya kept that from me for six months?”

“What was I supposed to do?” Atsumu shot back. “Call ya up and be like, ‘Hey, by the way, your little omega brother is datin’ someone, hope that’s okay with you’? Ya don’t answer my texts. Ya never visit. Ya don’t even ask how my matches go. Why would I tell ya anythin’?”

“Because I’m your alpha!”

The words exploded out before he could stop them. The room went silent. Atsumu stared, wide-eyed, and Osamu felt the weight of his own proclamation settle over him like a shroud. He’d never said it before. Not once since their father died.

Atsumu’s expression softened, just a fraction. “Yeah,” he said quietly. “Ya are. But ya haven’t acted like it.”

The accusation hung in the air. Osamu wanted to argue, to deflect, to retreat back into his comfortable cocoon of denial. But he couldn’t. Because it was true. He hadn’t been an alpha. He’d let their mother carry the burden. He’d let Atsumu drift away, untended, unprotected. He’d been a coward.

“I need ya to sign it,” Atsumu said again, softer this time. “Please.”

Osamu’s hand hovered over the form. He wanted to sign it. Knew he should. But something in him resisted—a stubborn, wounded pride that insisted this was wrong. That an omega shouldn’t need birth control. That an omega shouldn’t be with anyone but their pack. That an omega should be protected, cherished, kept safe. He knew these thoughts were archaic, toxic, born from the same rigid alpha conditioning he claimed to despise. But they were there, whispering.

“I can’t,” he said.

Atsumu’s face crumpled. “What do ya mean, ya can’t?”

“I mean… I can’t just sign this like it’s nothin’.” Osamu ran a hand through his hair, frustration tangling with guilt. “Ya come in here, drop this on me, expect me to be okay with it? Ya have a boyfriend. An alpha. And I didn’t even know.” His voice cracked. “I’m supposed to protect ya, Atsumu. That’s my job. And I failed.”

“Ya didn’t fail,” Atsumu said, but his voice wavered. “I don’t need protectin’. I can take care of myself.”

“Then why are ya askin’ me to sign this?”

Atsumu opened his mouth, then closed it. For a long moment he just sat there, hands gripping his knees, his scent a storm of emotion. Then slowly he stood up. Osamu thought he was going to leave. Wouldn’t have blamed him.

Instead, Atsumu walked around the kotatsu and, before Osamu could react, settled himself onto his lap.

Osamu froze. Atsumu was warm, solid, his weight familiar from a childhood of wrestling and sharing a bed during storms. But this was different. Deliberate. Atsumu looped his arms around Osamu’s neck and pressed his face into the curve of his shoulder.

“What are ya doin’?” Osamu asked, barely a whisper.

“Shut up,” Atsumu muttered against his skin. “Just… let me.”

Osamu’s arms stayed rigid at his sides. He didn’t know what to do. The alpha in him screamed to hold on, to wrap his brother in a protective embrace and never let go. But the part that had spent two years running was terrified that if he did, he’d never be able to let go.

Atsumu shifted, nuzzling into Osamu’s neck. Scenting him. Deliberately, gently, pressing his nose to the gland just below Osamu’s jaw and breathing in. The scent of sandalwood and honey mixed with Osamu’s own—rice, salt, and the faint earthiness of a neglected alpha. Messy. Imperfect. But it was them.

“I hate ya,” Atsumu whispered, but there was no venom in it. “I hate that ya made me do this. I hate that I had to come all the way here and beg.” His voice broke. “But I also love ya. And I need ya to be my alpha. Not because I can’t take care of myself, but because… because it’s not the same without ya. It hasn’t been the same since Dad died.”

Osamu’s throat tightened. He felt a hot sting behind his eyes and blinked furiously. His arms moved of their own accord, coming up to wrap around Atsumu’s back, pulling him closer. Atsumu let out a shaky breath and pressed a kiss to Osamu’s cheek, soft and warm.

“Thank ya,” Atsumu said. “For listenin’. For bein’ here. Even if ya’ve been a terrible alpha.”

A choked laugh escaped Osamu. “I’m sorry.”

“Ya should be.”

“I mean it.” Osamu’s grip tightened. “I’m sorry I left ya to deal with everythin’. I’m sorry I stopped carin’. I’m sorry I made ya feel like ya had to hide this from me.” He pulled back just enough to look Atsumu in the eyes. His twin’s eyes were red, wet, but bright with a fierce, stubborn love. “I’ll do better. I promise.”

Atsumu sniffed, wiped at his nose with the back of his hand. “Ya better. Because I’m not gonna come crawl into yer lap every time I need somethin’. I have a reputation.”

Osamu smiled—a real smile, the first in what felt like years. “I know ya do.”

They stayed like that for a long moment, wrapped in each other’s arms, the tension slowly bleeding out of the room. Then Atsumu shifted, reached for the pen on the table. Pressed it into Osamu’s hand.

“Sign it,” he said. “And then I’m gonna tell ya about Kiyoomi. And ya’re gonna listen.”

Osamu looked at the form. At the blank line. At his brother, still perched on his lap, trusting him in a way he hadn’t earned. He took a breath. Then he pressed the pen to the paper and signed his name.

Osamu Miya.

It felt like a beginning.

He set the pen down, and Atsumu crumpled against him, letting out a long shuddering sigh. “Thank ya,” he whispered again.

Osamu rested his chin on top of Atsumu’s head, breathing in the familiar scent of his brother. “Tell me about this Sakusa,” he said. “And I mean everythin’. If he hurts ya, I’ll kill him.”

Atsumu laughed, watery but genuine. “He won’t. He’s annoyin’ and clean-obsessed, but he’s good to me.”

“Good.”

They sat there as the sun dipped lower, casting the room in amber light. The onigiri on the floor lay forgotten. The silence of the house was no longer heavy—it was quiet, peaceful, filled with the soft rhythm of two brothers breathing in sync, finally finding their way back to each other.

Later that night, Osamu called their mother. She answered on the second ring, her voice tired but warm.

“Mom,” he said, gripping the phone tighter than necessary. “I’m sorry. I should’ve been helpin’. I’m gonna start. I promise.”

A pause. Then she laughed softly, a sound he hadn’t heard in a long time.

“It’s about time, Osamu.”

He smiled, looking over at Atsumu, who was sprawled on the couch scrolling through his phone with a lazy grin. He caught Osamu’s eye and stuck out his tongue.

Osamu flipped him off, but there was no heat in it.

He meant what he said. He would do better. Be the alpha Atsumu deserved, the son his mother needed, the pack leader his father would have been proud of. Long way to go, but for the first time in two years, the weight on his shoulders felt less like a chain and more like a purpose.

And across the room, Atsumu smiled to himself, the signed form tucked safely in his pocket, and thought, Finally.
