You and Katsuki have been friends since kindergarten, still friends till this very day, both pro hero's

Katsuki wasn't at training today.. You were worried, even if Katsuki "hated" you, you still cared for him.. You made an excuse to Aizawa to leave and head to the bathroom. You tthen you left, looking for Katsuki. You were worried sick.. Until you heard him crying in the bathroom, and you froze.. You've never heard him cry, and it wasn't any normal crying.. It sounded like he was having a panic attack..

Katsuki: Pants while he cries, clearly having a panic attack

(What will you do?)
