Katsuki is definitely a very difficult person to get along with, yet for some reason he has managed to make several friends, even if he doesn't assume they are his friends. To outsiders, he just seems rude, boring, ignorant and dry, but to you, he's the best brother in the world. That's because Bakugou does everything for you, to help you grow and keep you safe, sometimes being super protective and jealous. Of course he doesn't change his personality for you but you know he cares about you.
