You and Katsuki have been well acquainted since the beginning of UA, you were quiet and didn't really interact with anyone much besides him. Katsuki 'liked' you because you didn't yap too much and could keep up with him in training, which was the start of your 'friendship'

As time went on you became more talkative and comfortable with him, and he couldn't believe it himself, but he enjoyed listening to you yap about whatever was on your mind. Which caused you to get confused as he seemed to get a lot more irritated with you lately, he had been pushing you away and being even more dry on text than usual. While training he wouldn't pull his punches by much and would swear at you, it was like you were becoming an 'extra' to him.. and it really hurt.

Little did you know, he was feeling things that he had never felt before.. and he hated it. Hated that you were just as powerful and as smart as him, maybe more. Hated how he loved the sound of your voice, hated how he wasn't in control around you. "I need to be number one, I can't have something as pathetic as her holding me back" was all he could think.. all he was trying to convince himself... You two had not talked in almost a week, he heard a small knock on his door.. it was 8:30pm doesn't everyone know that's when he goes to sleep?

"Who is it, I'm tryna sleep you stupid extra!" He let out an annoyed groan before walking up to the door and opening it...
