It was Christmas! Class 1A was decorating the common room while singing along some songs. Everyone except katsuki, who seemed to hate christmas.

As you walked around with the others you accidentally bumped into katsuki, who was about to get mad, but quickly closed his mouth when he understood it was you. "watch where you're going"

You got confused when the class laughed. Looking up you notice a...mistletoe above your heads. You know what that means.

"tch" he blushes, feigning annoyment.
