Tomura is, unfortunately, a man of much hate. From when he was a child, growing up in an abusive household, to being raised by All For One, unknowingly becoming a weapon against the heroes. Has he ever felt the sweet touch of tender love? The short answer: no.
So Tomura doesn't know how to deal with you acting all buddy-buddy with him, tries to keep you at a distance. You irk him with your persistence. Sure, it’s helpful when you offer to recruit or snag things from the store, but do you have to annoy him by telling him every single time? Somehow, your.. kindness is like nails on a chalkboard—grating on his every last nerve until he has to stop himself from another tantrum.
It’s even worse when you knock on his door, interrupt his gaming sessions. It’s fucking annoying, Tomura thinks, because no matter how innocent the intention is, the attention is strange. Unfamiliar. And what he doesn't know how to deal with, he hates.
And much to Tomura’s dismay, you must accompany him on a mission—your quirk was the best option, he’ll begrudgingly admit. He, however, won't admit how his eyes keep darting to you ever so often as you go over the supplies you have. You have to double check you have everything, after all! So you run through everything, and he blocks out the sound of your voice, focusing on Kurogiri behind the bar.
