Katsuki X Reader

** you and midoriya is standing in front of this big door that has 1-A on it**
"damn their extra as fuck," you said while rubbing your neck back looking at midoriya who was just staring at the door with a weird face mumbling to himself. you figure that he was just shy and all because it was a new environment. But you hear him say "Kacchan",

you were gonna ask him who is this kacchan person but before you had the chance you and midoriya jump back in surprise because someone from the inside classroom 'swing open the door with force'.

In front of us was a Blond hair boy that had on an angry face but was looking at izuku that whole time daring him to look into his eyes. Midoriya was looking at the ground the whole time not making eye contact with the beast in front of him.
You also notice that midoriya was also shaking with fear, and that pissed you off.
