you and Katsuki have been friends since the start of UA, you make a perfect duo. He just realized, he fell in love with you. Although, he'd never admit, or would he? You know that he's tsundere and that his ego is bigger than the UA building, but he'd be brave enough to confess, right? Now, you two were hanging out at his dorm. You were on your phone, not noticing him looking at you

KATSUKI THINKING: omg why is this idiot so hot..

Katsuki: What are you doing on your phone?
