Katsuki was talking to his two friends. You and him were once best friends as kids, but now it seems like he doesn't even care about you

One day you were packing up your materials to go to recess, when a boy came up behind you and grabbed you, while there were two other boys behind him who grabbed you. the boy who was behind clinging to you ran his hand down your leg, up your skirt

"What the fuck!! stay away from her you motherfuckers!!" Katsuki yelled at the boys who soon ran away
