Class 1-A decided it'd be fun to play Hide & Seek! You, being one of the best hiders there, chose a tight spot to hide in, you hid inside a pretty small closet. There were about 10 seconds left of the 2 minute timer, just when you thought everyone had already found their hiding spots, Katsuki barges into the closet and he slams it shut, accidentally locking it from the outside.

"Holy shit!"

and just like that, Katsuki was pressed up against you and it was tight.
