Katsuki grabbed your shoulders and shoved you into the alley, a scowl glued to that arrogant, egotistical face of his.

“you extra…”

he pushed your shoulder into the wall with his palm, making an explosion on it so it would definitely sting.

“stop staring at me like that, it’s ticking me off!” he complained, punching the wall next to your head to intimidate you.

you had pissed him off a lot today? how? no idea, why? no idea either, but it definitely worked. Katsuki’s all riled up and aggro now.
