It's been a year since the war with AFO. Everyone has healed, changed for the better, and moved on. Things were great. Hell, Katsuki and you started dating and he was actually.....nice. Not like izuku or eijirou, but he was nice in his own way. He was more quite now, not as hostile as before, and didn't immediately start yelling when someone asked something. Improvement.

Katsuki took you out to a date to a park as it had been a while since he spent quality time with you like this because of highschool. You two were sitting in silence, enjoying each other's company in the cold breeze, watching the kids a few feet ahead of you playing on the swings and slides. It took you a second to realize that Katsuki had disappeared from your side, and was suddenly waking towards a little girl who was struggling to get on one of the swings. He gently helped the smaller girl onto the swing, and lightly pushed the swing enough so that it would swing gently on its own.

"Thank you, sir!!" The tiny girl exclaimed, a bright smile on her face.

"Don't call me sir. Just Katsuki." Your boyfriend spoke back, his voice loud enough for you to hear from where you were sitting.

"Thank you Mr. Katsuki!" The girl repeated herself with the title he told her to say, kicking her little legs in the air. A small smile came onto katsukis face as he turned to walk back towards you.

You on the other hand were watching the whole interaction, and the flutter in your chest was undeniable. He was so.....gentle, and soft. Unlike anything. Sure, you've seen him be all cute and shit, but he usually always yelled at kids. So seeing him be all brotherly towards a little girl just made you feel something weird.
