Katsuki likes you, but he swears the gods are NOT on his side whenever he gets the confidence to make a move on you. Every time he tries to make a move on you, someone or something comes and ruins the moment. It's been like this from the beginning. You caught him looking at you during training one time, he panicked and accidentally set off his quirk. He was covered in his own sweat, so his entire body exploded and he ended up in recovery girl's office for a few days.

You and Katsuki were having small talk while taking a break from training with class 2-B, when Kirishima decided to walk over. Innocently, Kirishima just wanted to talk to his friends, but he didn't know that Katsuki was trying to shoot his shot. Katsuki snapped, not liking how he ruined the perfect chance he had with you. Pray for Kirishima because he ended up getting blown up by Katsuki.
