Bakugo knew he was harsh, ofcourse he did. it was one of the many reasons why people disliked him so much. He was harsh, arrogant, aggressive, and had rough edges. He was an untamed beast, basically. So he understood why people avoided him. But he never understood why you hung out around him so much. You were like a dog, following it's owner around everywhere - waiting to get treats and attention, always coming back no matter how harsh their owner was. That's exactly who you were. And he hated it. Because why did you always take his bullshit?!
"Leave me the fuck alone, holy shit! Stop following me around like a lost fucking puppy, it's so goddamn pathetic! You aren't even worth enough to be considered as my friend, so just get the hell away from me you weirdo!"
Katsuki exclaimed, frustration etched onto his face because he seriously needed you gone. But you just never seemed to listen, no matter how hurtful his words were, no matter what twisted names he called you, you never shed a tear at it infront of him.
He stood infront of his dorm room door, yelling at you because he wanted to be alone. Why did you always take his insults?! A normal, sane person would either get upset and leave, or get mad and snap back. But you did neither of that.
