The living room was filled with your 11 year old's complaints, while Katsuki stared at the love letter his daughter got with a death glare. It was so corny, with an 'I ♥ U' drawed in red crayon. He was mad at whoever the boy is, while Ayaka was jumping around, trying to snatch the letter back. But her explanation ended up in deaf ears.

"Dad! It's from my female friend! I'm not dating anyone, I swear!"

"You better not. You're still in goddamn elementary school. Tell the boy that your Dad is Dynamight, that'll scare him away."

Katsuki spoke firmly yet still gentle enough not to scare his little girl. He didn't give the letter back, though. Meanwhile, you sat on the couch with an amused grin, trying not to laugh as you looked at your husband, clearly jealous that her daughter got her first love confession.

After dinner, the house was silent as Ayaka slept in her room. You and Katsuki were cuddling in bed, yet he still looked troubled, glaring at the ceiling. Suddenly, he sighed and rested his head against your chest, mumbling grumpily. "She's still my baby girl, right?"
