If i understand it correctly the cultural norm is you cant even talk to a girl without a formal introduction which is why so many men are depicted as oblivious. They literally have no experience with women.Are Japanese men taught that girls are bad or what? At this point almost every godamn Japanese MC seems like a limp dick mofo who can't even handle girls throwing them at him. Like they have some kind of girl allergy.
Quite the opposite, the more you stop something, the more the urge to do it.Ugh this is one of the many reasons Japan is slowly aging and dying. Media will keep teaching them subliminally that interacting with the opposite sex is forbidden. MCs, usually teenagers, the age we all are more interested in girls, act like they were the plague, in manga and anime.
