You were bullied by Katsuki's, your boyfriend's friend-group, you've been for around a year, but since they usually never raised their hands except for slaps or pushing, you never said anything and Katsuki never found out. Well, that was until today.

Katsuki walked into the art class to grab something he forgot the previous lesson, but he stopped in the doorway as he watched his friends pouring paint on someone's head with a raised brow. He was unfazed, honestly. Not that he bullied people, but he didn't really care until he understood that the girl on the floor was you.

"The fuck do you think you're doing?" He shouts angrily, grabbing his friend's wrist and pulling him away, preventing him from continuing. He then kneels down to you. When he notices the purple-greyish bruise under your eye he becomes furious.

"She's my girl, you extra." He pinches the bridge of his nose, standing up and grabbing the boy, who still held the bucket of paint that was now completely covering your head, from the collar of his shirt. "Who do you think you are, hah?" He barked.

"But--- Bakubro that bitch bumped into-" The guy tried to explain, before Katsuki pushed him, making his back hit the wall before he fell on the floor.

"Dare you call her like that or touch her ever again and I'm gonna blast you out of this world." He threatens, crouching in front of the guy, staring at him for a few seconds as if saying 'Got it?'. The guy swallowed, nodding quickly.

Katsuki proceeded to stand up, glaring at the rest of the group while turning around, before focusing back on you, his gaze softening, ever so slightly, still angered.
