Reverie: Compilation of Jujutsu Kaisen Childhood Cuteness Fics

All's Well That Friends Well

While Yuji was an extroverted child by nature, Nanami still thought he might need time to adjust to preschool. So when Yuji easily waved goodbye as Nanami dropped him off for his first day at Pre-K, it soothed some of the paternal worry.

"Otouchan, how long is school?" Yuji wrapped his arms around Nanami's neck and squeezed. "Is it very long?"

"You'll be here for a few hours, Yuji-kun. But I'll be back. You'll be having so much fun you won't even miss me." He promised, kissing the young boy's forehead. "If you need anything, just ask the teacher for help, okay? Remember how we practiced and...?"

"Raise my hand!" Yuji smiled.

"That's my boy." Nanami ruffled his hair and stood up. "Have a good day, Yuji-kun. And have some fun."

"Okay!"

. . . . .

Yuji Itadori made having fun his mission. From the moment he stepped foot into the classroom, he curiously trotted around the room asking question...after question...after question.

"What about that? Why do you have that?" He asked Ms. Chotto, pointing at the hundredth object his little eyes had landed on.

"Yuji, honey," Ms. Chotto laughed. "You're such a curious little thing, aren't you? Those are my plants and I keep them on the top shelf so none of my students accidentally eat them. They can hurt your tummy."

"Then why do you have them?"

"I'm keeping them here for a little bit until I can find a space for them at home." She explained, turning away to separate two girls from fighting over a doll. "Go find someone else to play with, Yuji, okay? I have to help some of the other children right now."

Yuji pouted but did as he was told. Pre-K proved to be one of the most fascinating places he'd ever been! He'd already spoken to just about everyone in the classroom, when the door opened to reveal another little girl.

What surprised Yuji wasn't how tightly she clung to her father, but her hair. Pink! Just like his!

As soon as Ms. Chotto got the pink-haired girl detached from her father, Yuji stood patiently to the side. He watched her hide in Ms. Chotto's legs until she peeked out at him.

"Hi! I'm Yuji!" He beamed.

Her wide, brown eyes looked up at Ms. Chotto and then back at him.

"I'm Besu." She whispered. In fact, Yuji barely heard her.

"You sure are quiet." He said bluntly. When she seemed embarrassed by that, Yuji pointed towards a pile of blocks on the rug up front. "You wanna go play blocks?"

Ms. Chotto muttered something into Besu's ear. Besu whined back at her, but Ms. Chotto delicately coaxed her in Yuji's direction. Yuji led the way over to the blocks and Besu sat by him silently.

"I like to build castles. What do you wanna build?" Yuji asked as he got to work. A triangular orange block looked perfect to fit on top of his green stack.

Besu shrugged her shoulders as she grabbed a few square pieces to fit together. Yuji gave her time to give it a specific shape, but when he still couldn't tell what it was by the third row, he spoke up.

"What is that?"

Once again, Besu shrugged. Yuji huffed, feeling disappointed. He'd expected her to be just like him since she'd looked so similar. But she barely even talked! Sensing this, Besu cleared her throat.

"I just like putting them together. But now I'm making a watermelon." She explained, picking off a few blue pieces and replacing them when red and green.

"My dad put watermelon in my lunchbox! Wanna see?" Yuji stood before she answered.

"I don't think we're sposed to do that." She glanced at Ms. Chotto and then Yuji's lunchbox. "You could get in trouble."

"Nuh-uh. It's my lunchbox!" Yuji said matter-of-factly.

But when he went to grab it, Ms. Chotto put a hand on his shoulder.

"Yuji-san, it's not time for lunch yet."

"Can't I show Besu my lunch?" Yuji frowned.

"Why don't you show her when it's lunchtime? That way you can both show each other what you have." Ms. Chotto offered.

"Okay!" Yuji agreed, before toddling over to Besu. "Hey, Besu! Let's wait until lunch and then I can see what you packed, too!"

"Father made me stew."

"Oh, boy! Will you share?"

"...well, okay."

. . . . .

While Nanami waited outside the classroom as kids shuffled inside, a man with wild pink hair waited with him. He couldn't help but stare. Just like Yuji's, and that's not common. I wonder if he's of any relation.

"You waiting on your brat, too?" Sukuna quirked a brow and stuffed his hands in his pockets.

"I'm waiting for my son, yes." Nanami answered. "It was his first day."

"Mine too. You have any trouble dropping him off?"

"I thought I might, but he didn't seem upset. He's more outgoing, though, so I wasn't too surprised."

"I had to pry my daughter from me." Sukuna scoffed, shaking his head with a smile.

"Ah, she must be a daddy's girl, then. Does she have you wrapped around her finger yet?" Nanami normally wasn't one for small talk, but the conversation helped him remain patient as he watched through the window while the teacher struggled to wrangle a boy into his bookbag.

"Absolutely not!" Sukuna huffed, but he turned his head away. "That is...I don't give her everything she wants."

Nanami couldn't help but chuckle.

"Don't worry. I'm the same with my son. He's my first."

"My daughter is my first, too."

And then the floodgates unleashed. More parents began filing down the sidewalk towards the portable classroom, but Yuji and Besu were the first at the door. Both of them raced and planted themselves directly into their father's arms.

"Otouchan! You won't believe it! That girl looks like me!" Yuji turned to Besu to see her the most animated she'd been all day, jabbering on to her father with bright brown eyes. "She's real quiet though...like Fushi-kun."

"I see. Did you have fun, then?"

"Yeah! I made a best friend!"

And Nanami smiled when Yuji turned to Besu, waving goodbye as Sukuna carried her away.
