I find it really interesting how much more negatively everyone is reacting to what is essentially just "male tsundere," despite how much some people want to exclude him from that category. I mean, I wish he'd get yeeted from the story too because I want more fluff time, but he's hardly a monster. The worst we've seen him do is what amounts to a light bonk - which is extremely common in manga and I doubt was intended to stand out at all. Compared to more extreme female tsunderes (Full on assault in chapter 2 of Toradora?) this guy is tame.
