Manipulates women in order to have sex with them, tend to call them bitch, now doesn't hesitate to hit a woman who was punching him because he doesn't want to leave her appartment. Wow, what a great main character. Totally not a dangerous toxic and sexist person.
I haven't read much of those kind of Korean hentai, but so far all the ones I've read are borderline pro-rape, and wants the reader to know that condom sucks, that a man shouldn't use one because it feels so much better without. Fucked up stuff.
