Komori was getting beaten up. Bad. Bullies ganged up on him and physically assaulted him, shoving and pushing him, and they even stomped on his nose. Even as Komori cried out for mercy, they didn't stop.

Bully 1: Just give up, freak. No one likes you. Bully 2: Not even your cousin (Sakusa) came to help you. But he's a germaphobe anyways, we'd batter him any day. Bully 3: Laughs and shoves Komori into the mud.
