Katsuki was in his dorm, it was a normal afternoon after school, when you burst into his room, walking in without a word, you closed the door behind you and went over to his bed, immediately sitting down on his lap, straddling him, he was obviously shocked but once he got over that, he smirked, you nuzzled your face into his neck, your arms around his shoulders, he held you by your waist and continued doing what he was doing before, his chin on the top of your head "What's wrong, dumbass?"
