The Weight We Carry

The first thing Atsumu noticed when he woke up was the weight.

Not the heavy kind, like a bad dream or a looming practice. More like someone shoved two tennis balls under his skin overnight. He blinked at the ceiling, confused, then looked down.

His chest was not his chest.

The soft curve pressed against his sleep shirt—an old middle school jersey that used to hang loose. Now it was tight at the seams. He sat up slow, palms flat against the new swell, and his brain just stopped.

"What the hell?"

He scrambled out of bed, yanked open the closet, and dug until he found the biggest shirt he owned: an oversized hoodie from a convenience store their mom bought two sizes too big on purpose. He pulled it on. The baggy fabric swallowed him, but if you looked close, the bump was still there. He hunched, tugged the hoodie down, and decided he'd just never leave his room again.

But breakfast called.

He shuffled into the kitchen, eyes on the floor, and slid into his seat across from Osamu. His twin was halfway through a bowl of rice, chopsticks frozen, staring at him with that flat look he'd perfected over seventeen years.

"What's wrong with you?" Osamu asked.

"Nothin'."

"You're wearin' that ugly hoodie. In June."

"It's comfortable."

"It's stupid."

Their mom turned from the stove, spatula in hand. She took one look at Atsumu—the way he held his arms crossed over his chest, the flush creeping up his neck—and her expression softened. Something clicked.

"Osamu, eat your breakfast."

"I am eatin'—"

"Then eat it quietly."

Osamu frowned but shut up. Atsumu shot his mom a grateful look. She just nodded and turned back to the pan. He picked at his rice, appetite gone, chest tight with something like shame.

That was six months ago.

Six months later, Atsumu learned the universe had a sense of humor, and it wasn't funny.

He stood in the bathroom, staring at the stain on his favorite volleyball shorts. First period. He wanted to cry. Not because it hurt—though there was a dull, cramping ache low in his belly—but because he had no clue what to do. His mom had explained the basics a few months back, after the chest thing, but theory and practice are different when you're seventeen and bleeding through your underwear.

He managed to wrap a towel around his waist and shuffle to her room. She took one look, pulled him into the bathroom, and handled everything with the calm efficiency of a woman who'd raised two boys and was now navigating a third kind of child. She showed him how to use the pads, said it was normal, didn't make a big deal. Atsumu wanted to hug her forever.

When he finally came out, pale and shaky, Osamu was leaning against the hall wall. He had a chocolate bar in his hand.

"What?" Atsumu snapped.

Osamu shrugged, holding it out. "Mom said you might want this."

Atsumu took it, muttered thanks, and ate the whole thing in three bites. The sugar helped. So did the fact that Osamu didn't say anything else.

But over the next few days, the chocolate kept appearing. On his pillow. In his volleyball bag. Next to the remote. Osamu never said a word, just left them like offerings to a grumpy god. And Atsumu, for all his pride, didn't say thank you again. He just ate them.

Osamu noticed the mood swings too. The way Atsumu would snap at nothing, then go quiet. The way he clutched his stomach during commercials. The way he curled up on the couch with a heating pad from their mom's closet. Osamu didn't really understand—not in a way he could put into words—but he understood his twin was hurting. And he understood that chocolate helped.

So he kept bringing it.

The present day arrived like any other Tuesday.

Late afternoon, golden light slanting through the living room windows. Atsumu and Osamu locked in a battle of wills over the TV remote. Atsumu wanted to watch a replay of the last nationals match. Osamu wanted a cooking show. Neither would budge.

"You watched that match three times already," Osamu said, holding the remote just out of reach.

"Because it's important. Gotta study their formations."

"It's a rerun of a rerun."

"So is your stupid cooking show."

"It's not stupid, it's educational."

From the armchair, Suna Rintarou watched them with the lazy amusement of a cat watching dumb mice. He'd come over to study, but that had devolved into this. He wasn't complaining.

"Just share the remote," Suna said flatly.

"No!" they said in unison.

Atsumu, fed up, launched himself at Osamu in a tackle that was more desperate than strategic. He landed square in his twin's lap, legs straddling his thighs, and snatched the remote. "Ha. Victory."

Osamu grunted. "Get off, you're heavy."

"I'm not—"

But Atsumu stopped. Because he felt something. A wet, spreading sensation against his thighs. He'd forgotten: day three of his period, and he'd meant to change his pad twenty minutes ago.

He looked down.

Osamu's gray joggers were darkening near his hip.

"Oh," Atsumu whispered.

Osamu looked down too. His face went through a journey: confusion, realization, then careful, practiced neutrality. Suna raised an eyebrow but didn't say anything.

"I—I'm sorry," Atsumu stammered, scrambling off. He grabbed a throw pillow and pressed it against his own pants, face burning. "I didn't mean to—it's the pad, I forgot to—I'll go clean up."

He fled to the bathroom.

Osamu sat there for a long moment, staring at the stain. Suna broke the silence.

"You're not gonna freak out?"

"Nah," Osamu said, though his voice was tight. "It's fine. Happens."

"Does it?"

"Shut up."

He stood up, grabbed clean pants from his room, and changed quickly. When Atsumu came out of the bathroom, face red and eyes wet, Osamu was waiting in the hall.

"Hey."

"Don't."

"I'm not gonna make fun of you, idiot. It's fine. I've got other pants."

Atsumu sniffled. "They're your favorite ones."

"They're just pants. They wash."

Atsumu looked at him, vulnerable in a way he rarely let himself be. Osamu didn't look away. He just reached out and ruffled his brother's hair, a gesture so familiar it almost made Atsumu cry for real.

"Come watch your stupid match," Osamu said. "I'll make tea."

But as Atsumu shuffled back to the couch, Osamu stood in the kitchen and let his face fall. He'd noticed the way Atsumu disappeared to the bathroom every half hour. The overnight pads in the trash that looked like they'd lost a war. The pale skin, the extra sleep, the less eating.

Something wasn't right. And Osamu was scared.

---

Three days later, Atsumu fainted for the first time.

In the middle of the hallway. Walking from his room to the kitchen, and his legs just gave out. One second upright, the next on the floor, vision swimming, ears ringing. Osamu found him, called their mom, and together they got him on the couch with water and a cold cloth.

"I'm fine," Atsumu insisted. "Just stood up too fast."

Their mom exchanged a look with Osamu, but she didn't push. She brought him soup and told him to rest.

Day two of the fainting: Atsumu collapsed in the bathroom. Caught himself on the sink, but by the time Osamu got there, he was on his knees, breathing hard. This time, Osamu didn't let it go.

"You're going to the doctor."

"I said I'm fine."

"You're not fine. You're bleedin' through pads faster than I change socks."

Atsumu flinched. "That's gross."

"You know what's grosser? You passin' out on the bathroom floor. Get your ass in the car."

But Atsumu refused. Hated hospitals. The smell, the waiting, the sterile white walls. He promised he'd go if it happened again.

Day three: it happened again. In the kitchen, cracking his elbow on the counter on the way down. Their mom bandaged it while Osamu stood in the doorway, jaw tight, fists clenched.

Day four: Atsumu stayed in bed, too weak to argue. Osamu brought him chocolate, but he only managed two bites before setting it aside.

"I'm worried about you," Osamu said, voice low.

"Don't be. It's just a heavy period. That's normal."

"Is it normal to faint four times?"

Atsumu didn't answer.

Day five, the fainting came again.

They were in the living room. Suna had come over for real studying this time, and Osamu was making onigiri in the kitchen. Atsumu was on the couch, wrapped in a blanket, watching some mindless variety show. He looked up to ask Suna a question, and then his eyes rolled back, and he slid sideways off the cushion.

Suna caught him before his head hit the floor.

"Osamu!" Suna's voice cut sharp.

Osamu dropped the rice ball and ran. Found Atsumu limp in Suna's arms, skin paper-pale, lips almost blue. This time, Osamu didn't ask. He didn't reason. He knelt, scooped Atsumu up, and carried him toward the door.

"We're goin' to the hospital," he said, leaving no room for argument.

Atsumu stirred, groggy. "No… I'm fine…"

"You fainted five times," Osamu said, and his voice cracked. "Five times, Tsumu. You're not fine."

Atsumu, too weak to fight, let his head fall against Osamu's shoulder. Their mom met them at the door, keys in hand, face set.

"I'll drive."

---

The emergency room was a blur of lights and voices and needles. Atsumu wheeled away for tests. Osamu sat in the hard plastic chair with Suna beside him, staring at the linoleum floor. He didn't realize he was shaking until Suna put a hand on his knee.

"He'll be okay."

"You don't know that."

"I know you'll make sure of it."

Osamu wanted to believe him.

An hour later, a doctor came out with a clipboard and a kind face. She explained that Atsumu had severe menorrhagia—abnormally heavy menstrual bleeding—which had led to significant blood loss and anemia. The fainting was from low blood pressure and insufficient oxygen. They were starting treatment: hormonal therapy to regulate the bleeding, iron supplements, and careful monitoring.

"He'll need to rest for at least a week," the doctor said. "And follow up with a specialist. But he's going to be fine."

Osamu let out a breath he didn't know he'd been holding. "Can I see him?"

"Of course."

Atsumu was propped up in a hospital bed, an IV drip in his arm, looking small and pale against the white sheets. He looked up when Osamu entered, and for a moment, neither spoke.

"You were right," Atsumu said quiet.

"I know."

"I'm sorry I made you worry."

Osamu pulled up a chair and sat down heavy. "Idiot. You don't gotta apologize for bein' sick."

"I just didn't want it to be a big deal."

"It is a big deal. You could've really hurt yourself." Osamu's voice was rough. "I can't… I can't have you passin' out and not wake up."

Atsumu's eyes glistened. "I'm awake."

"Yeah. Good." Osamu cleared his throat. "You want some chocolate? I snuck some in my pocket."

Atsumu laughed, weak but real. "You're always bringin' me chocolate."

"Someone's gotta put sugar in that sour personality."

"Shut up."

But he took the chocolate. Unwrapped it slow, took a bite, closed his eyes.

"Thanks, Samu."

Osamu said nothing. Just sat there, watching his brother eat, and for the first time in five days, he felt like he could breathe.

---

They discharged Atsumu the next morning with a prescription and a stern lecture about listening to his body. Their mom drove them home, and Atsumu collapsed into his own bed with a groan of relief. Osamu hovered in the doorway, then disappeared. Came back ten minutes later with two cups of hot chocolate and a bag of marshmallows.

"Movie?" he asked.

Atsumu nodded.

They settled on the couch, blankets piled high, remote forgotten on the coffee table. Suna had gone home after the hospital, but he'd texted a single emoji: thumbs-up. Osamu sent back a middle finger emoji. Their way.

They didn't actually watch anything. Atsumu leaned against Osamu's shoulder, and Osamu let him, the weight familiar and right. The chocolate was warm and sweet, and for a while, neither said a word.

"I'm glad you didn't give up," Atsumu murmured.

"On what?"

"On makin' me go to the hospital."

Osamu snorted. "You think I'd let you bleed out on the couch? You owe me a new pair of joggers, by the way."

"I'll buy you a hundred."

"You better."

Atsumu smiled, small but real. "Thanks for bein' there. Even when I was bein' a jerk."

"You're always a jerk. I'm used to it."

"I mean it."

Osamu was quiet for a moment. Then he put his arm around Atsumu's shoulders and pulled him closer.

"I know. And you're welcome. Now shut up and drink your chocolate."

They sat there as the evening light faded, wrapped in the silence that only twins could share. The remote forgotten. The match didn't matter. Neither did the cooking show.

All that mattered was this: two brothers, a cup of chocolate, and the quiet understanding that they'd take care of each other. Even when it was messy. Even when it was scary.

Especially then.
