Practically every vn heroine type has some psychological issue to deal with for drama, lol. This makes their stories interesting, but in the end, you're dealing with maladjusted people of some kind most of the time. When it gets to actual disorder level, I really don't want to get involved; I have problems of my own to deal with. Well, actually I might like a kuudere. Feel like a bit of one myself, and like seeks like I guess.
