Caregiver: Hinata, Yamaguchi, Tsukishima
Regressor: Kageyama

Hinata leaned over, poking Kageyama.

"What do you want?"

"Your notes."

Kageyama sighed. He tossed over his notebook, writing down things in a different one. For that whole class period, he'd ignored the ginger and everyone else. It was relaxing and allowed his kind to fog slightly.

Hinata poked him again.

Kageyama sighed. "What?"

"Are you coming to afternoon practice?"

"Of course I am, dummy."

Hinata laughed. "Cool." He climbed over into Kageyama's lap. "I'm gonna arm wrestle with Nishinoya today!"

"Cool." Kageyama shifted uncomfortably. He hated people sitting in his lap when he felt a bit foggy.

Hinata poked his cheeks. "Kageyama~"

"What do you want?"

"Can I have your jacket?"

"No." Kageyama shifted again. Practice would be in ten minutes. He just had to wait ten minutes. It would be okay if he could just-

"Tobio! Tobio! Tobio!"

And now he was frustrated. Lovely. "What do you want?!"

Hinata startled. He went quiet, noticing Kageyama's little bits of fiddling. That was a habit when he was trying not to slip and it would get worse from there.

"Well?! What is so important?!"

Hinata got up, grabbing both of their bags. "Let's go."

Kageyama watched, confused.

"Hey, come on. We can walk down to the gym. We'll relax there."

Kageyama walked with him, silent. He got to relax? That was amazing... He hadn't gotten to relax recently.

Hinata discovered that the other first year's we're in the club's room and paused. "Hm."

Kageyama went into the corner of the room, sitting down. Yachi looked up as he sat down, confused. "You're early? I thought you and Hinata had more studying to do."

Kageyama didn't respond, just holding Hinata close when the ginger sat down. His body felt nice against his own. He yawned, huddling into him.

Yamaguchi looked over, stopping his conversation with Tsukishima. He got up, opening the cabinet next to him. He found a blanket and wrapped it around Kageyama. Kageyama whined softly at him, not expecting the touch.

"Sorry, sorry." Yamaguchi rubbed his hair.

Kageyama hummed. He stuck his thumb in his mouth, sucking on it and huddling into Hinata's side.

"Shove it where the sun doesn't shine Daichi! I don't care about the test!"

Kageyama was startled again. He was confused, not expecting the outburst. The third years were walking in, Suga being loud as usual and the other two sighing behind him. Kageyama whined, started to get fussy. Hinata turned and covered his ears. "Shhhh, shhhh, shhhh. I know. I know."

Sugawara looked over. He gasped. "Crap." He hurried over, cupping Kageyama's face. "Hey, hey. I'm sorry. Was it too loud?"

Kageyama nodded, sniffling.

"Was today not a good day? Hm?" Suga rubbed his hair, smiling fondly at him. Kageyama gulped softly. "That feels nice?"

Kageyama realized that he was safe to do as he needed now and slipped fully into his headspace. He drooled a bit, giggling as Sugawara rubbed his hair.

Hinata wiped his chin and kissed Kageyama's forehead. "Do you want to come sit in the gym?"

"Mhmm!" Kageyama put his head on Hinata's chest. "Papa."

Hinata laughed. He softly. "It's me, little guy. Let's go."

Kageyama toppled into him, whining.

"What is it?" Hinata stroked his hair. "Are you feeling wiggly?" Kageyama nodded, frustrated. He laid on the floor, close to starting to cry or throw a small fit. Hinata pat his stomach. "Wiggle wiggle." Kageyama shifted, the energy not gone. He hated this feeling and overstimulation was difficult for him. Hinata got up hurriedly, distracting him. "Come on love. Gym time."

Kageyama composed himself, trying to hide his state. Sugawara and the third years hurried over. "How about we help him out?" Walk down there as a group?"

Kageyama held onto Hinata's hand, walking with him. He was easily hidden in the group as they all walked to the gym.

Kageyama was put up on the stage where he was handed a blanket and stuffed bear. Kageyama watched his team, fiddling and playing with his bear.

Hinata was practicing with Sugawara, perfectly fine. Kageyama started to feel off again and needed attention. He got up, walking over and struggling a bit.

"Papa... Papa..." Kageyama slowly went up to his caregiver.

Hinata didn't notice him, backing up hurriedly to hit the ball heading to him. His hand collided with Kageyama's cheek, scaring him. Hinata turned around, sitting him down hurriedly. "Tobio... Tobio... It's okay."

Kageyama started to cry, terrified by the hit and the pain getting to be too much. Others in the room noticed as Kageyama started to sob. They were quick to get things to help him with and sat by him, calming him.

Kageyama huddled into Hinata, shaky. Asahi rubbed Kageyama's back, worried.

"What happened?"

"I accidentally hit him." Hinata kissed Kageyama's head. "I'm sorry buddy."

Yamaguchi shuffled closer with Tsukishima. The blond reached forward, lifting him out of Hinata's lap. Yamaguchi wrapped him up in a blanket and Tsukishima rocked him. Daichi spoke up. "I can drive him home."

Kageyama whined at Tsukishima. He pinched his nose and headbutt his shoulder. "Meanie."

Tsukishima sighed deeply. Yamaguchi laughed. "Tsuki, it's okay. This is how you act when this happens to you."

The larger of the two flushed. "Don't talk about it."

Hinata stuck his tongue out. "Rude."

Tsukishima shifted Kageyama so he would calm down and bounced him lightly. Kageyama drooled on his shoulder, giggling. "I'm just glad I know how to take care of this."

Suga hummed. "Is that because of how you act?"

"Enough insulting his little mindset," Yamaguchi stated softly. "Tsuki gets fussy like Kageyama and that's okay." He rubbed Kageyama's cheek. Kageyama giggled loudly at him, hiding in Tsukishima's chest.

Hinata felt a bit bad for being irresponsible with taking care of Kageyama but scooted over. "Hey, there little guy. You want a bottle?"

Kageyama hummed.

Hinata bought some milk from the vending machine. He filled a baby bottle in his bag, shaking it hurriedly to try and warm it.

"Hey, Hinata?"

"Oh. Hey Yamaguchi."

Yamaguchi sat down by him. "Don't feel bad about the way Kageyama acts. He's sweet. But he also doesn't know how to react when he's like that. Tsuki isn't trying to take him but he loves being a caretaker when he doesn't regress. It's comforting for him."

"I get it. I don't think I can do it very well though. Kageyama always gets so mad when he's around me but when you guys do it then he giggles and has fun." Hinata stared at the bottle. "I'm so bad at this..."

Yamaguchi hummed. "Well... You can bike to Tsuki's house. It's where I'll be tonight and we can all have a sleepover where we teach you how to take care of Kageyama. Bedtime is the most difficult for littles like him."

"Sounds good to me." Hinata stood and walked into the gym. "Hi, there little guy!"

"Mm." Kageyama grabbed the bottle. "Papa!"

"That's me." Hinata sat down, easing the bottle to Kageyama's lips. Kageyama cuddled into Hinata, gulping down the drink. He was happy at the moment. That was good news.

Daichi drove him to where he needed to be, all of the first-year boys there. Kageyama was sitting on the ground, holding a large stuffed bear.

"Wook Papa! Wook!" Kageyama held up the bear.

"That's lovely, sweetheart." Hinata sat down and kissed Kageyama's forehead. "Where'd you get that little one?"

Kageyama pointed to Tsukishima, who was going through the closet. "Tsuki gabe it for seep."

"Ooh. Did you say thank you?"

"Dank you!"

Tsukishima glanced back. "No problem little one."

Kageyama hummed into the bear. Yamaguchi poked his head into Tsukishima's room. "Hey Hinata, come here."

Hinata followed him to the kitchen, confused. Tsukishima's mother was sitting in the kitchen, not phased at all.

"Alright so, usually I have to trick Tsuki into taking melatonin to sleep. I have really good-tasting gummies for this." Yamaguchi went back into the room. "Hi, buddy! Do you want some candy?"

Kageyama looked up from playing with the bear. "Papa?"

Hinata took the gummies and leaned down. "Open for the choo choo."

Kageyama opened his mouth, giggling. Hinata laughed with him.

"What is it? What is it, silly boy?"

"Choo choo!"

Hinata popped one of the gummies into Kageyama's mouth. "Yum?"

"Yum!"

Kageyama ate the other one and Tsukishima found another toy. He watched as Kageyama interacted with everything, his fascination with everything being a good sign.

That was until he was playing and bumped his head against the bed frame. He started to fuss, crying a bit. Yamaguchi leaned down, trying to calm him before he had an absolute fit.

"Hey, look. It's okay. It's okay little guy."

Kageyama screamed, leaning away. Tsukishima hurried to sit up and try to help, knowing what would happen if he wasn't calmed. "No touch! No touch!"

Tsukishima gulped. "Ah, I don't..."

Yamaguchi got Hinata out of the kitchen where he was attempting to heat a bottle. "Kageyama is getting really close to having a temper tantrum."

Hinata went into the room and laid down on the floor next to Kageyama. "Hey, buddy." Kageyama kicked, huffing and puffing with watery eyes. "You're okay. Shhhh, shhhh, shhhh."

Kageyama sniffled. He climbed into Hinata's lap. "Papa hurts."

"I know, I know." Hinata held his face in his hands. "But it's okay. Where's your boo-boo?"

Kageyama pointed to his head. "Owy."

Hinata held him closer. He kissed the spot over and over. "All better?"

"Mhmm." Kageyama kissed Hinata's cheek. "Papa."

Hinata smiled.

Kageyama yawned softly.

"Oh goodness, what a tired baby..."

Kageyama cried out. "No tired!"

"No tired?"

Kageyama looked to the other boys, getting frustrated at their pajama states. "No tired!"

Hinata gently rocked him back and forth. "Why not? Do you want snuggles? Hm? Lotsa snuggles for a pretty little boy."

"Pretty?"

"The prettiest." Hinata rocked slower, now swaying. "My pretty boy..."

Kageyama put his head on Hinata's chest. He flushed, fiddling. Getting flustered was always really easy for him in this state. Hinata was good at making him feel comforted and making him feel good about himself.

Hinata laughed. "Bedtime?"

"No," Kageyama whined loudly.

Yamaguchi handed him a bottle. "It's got a bit more of the candy."

Kageyama looked up and made grabby hands. Hinata eased the bottle to his lips. "Sweet boy..."

Kageyama relaxed back into Hinata, growing drowsy. Hinata scooted back and got them on the futon behind him. Kageyama started to doze off, curling in on himself to feel even smaller than his body was. Hinata gently ran his fingers through his hair, kissing his forehead.

Kageyama leaned back. He started to fall asleep, suckling slowly on his bottle. Hinata eased him to slowly let go of the bottle, smiling as Kageyama started to snore. Yamaguchi looked over from settling down. "Good job Hinata."

Hinata hummed. He closed his eyes, relaxing. For once he'd done this correctly.

Yamaguchi smiled at him, looking over Tsukishima's shoulder. Tsukishima smiled. He had the blond laying on his chest, stroking his hair.

"Did he regress?"

"No, he just sleeps like this."

"Shut up Yamaguchi." Tsukishima burrowed into Yamaguchi's chest. "I'm trying to sleep."

"Well, I'm sorry." Yamaguchi kissed his hair. "Night night Tsuki."

"G'night."
