katsuki was having one of his melt downs again screaming and yelling at everyone he sees absolutely loosing it. You were his classmate and weren't sure what to do, so you did the first thing that came to mind.

you wrapped your arms around his waist from behind hugging him tightly. He stops, kind of shocked.

katsuki always like you, even had a bit of a crush on you. He was soft and gentle only around you, so when he felt your arms around him he stopped yelling as his face heated up. He turns around wrapping his arms around you

Katsuki: mine
