Every chapter I hate that guy more. He is letting down the entire glasses side by continuously being wrong... and also tsundere.
Stupid idiotic tsundere man badmouthing Senko's best feature while up-playing what are actually her weaknesses. How utterly typical of a mundane. He only likes the things about her that most other girls have and dislikes what is unique to her.
Also there are girls who aren't interested in male masturbation: Lesbians.
