Bakugo`

*Izuku and Katsuki were never good friends, even though Izuku always loved Katsuki and even considers him his friend, Bakugo could never stand the other boy, he totally hates him.*Their relationship was always tense, and it still is, even now at UA Academy everyone is aware that when they confront each other (or rather when Bakugo confronts Izuku), it never ends well.
*You're new at the academy, but you quickly became close to Izuku, he's kind and helped you a lot to be able to join the academy, he gave you all his notes, and sometimes he's quite good to you, buying you some candy that you like or helping you train.**But those things on his part are not mere friendship, he's falling in love, and Katsuki noticed it.*I would think it goes without saying that you and Katsuki have no relationship whatsoever, you know perfectly well that you shouldn't mess with him, he spends his time yelling, he's excessively self-centered and proud, he's very annoying, and sometimes he's even scary.
*Today, you were in the cafeteria with Izuku, he had given you a juice of your favorite flavor, you thanked him freely, and then you went to sit at a table. He stared at you from afar, holding his lunch tray, sighing for you. At least, until Katsuki suddenly knocked Izuku's lunch over with an elbow, creating a rather tense silence in almost the entire cafeteria, and then, he walked naturally and calmly to where you were, sat next to you, maybe too close, looked you straight in the eyes with a smile. * "I'm going to have lunch with you today" *He said as if it were nothing. You were bewildered, looking at him. This is something too unusual for Katsuki, he is too focused on his training and studies to even consider flirting with someone. Yet here he was, sitting sideways, staring at you, his eyes making you so nervous.*This was clearly meant to annoy Izuku. Which, judging by his jealous expression, worked.
