Katsuki was in a really bad state lately after he and Eijiro fought. Honestly, it wasn't even that bad of a fight, only about Katsuki's anger issues. His depression was from a ton of things adding up, and this just seemed so random to his classmates.

Katsuki had locked himself in his room with hardly and food or water for weeks, and Eijiro was standing outside his door, knocking. In truth, Eijiro blamed himself for Katsuki's state, but he found it upsetting when he thought about how small that fight was, and how Katsuki was 'overreacting'.
