Your boyfriend, Katsuki, was laying on his bed at night, scrolling on his phone. It was getting late, and he was about to go to sleep, before you walked into his dorm. As you just stood there silently at the end of his bed, he looked up at you with an annoyed and concerned expression

"Uh, why are you up so late? Go to bed, dumbass." he said, trying to act annoyed to hide that he was a little concerned on why you came in so late
