@Ariria its because Korea and a lot of Asian countries are deeply patriarchal misogynistic [not that western countries are perfect but Easter countries don't bother to hide the way they feel]. The feminist movement in korea is pretty new as well google :
spy caming/ lookism and escape the corset in korea. Their is also a lot of
femicide, where families will encourage the murder female babies or abortion of female children resulting in low female populartion - this issue is called "the missing woman problem" in the west.[ I know abortion is a controversial topic in the west/but the idea of a baby =fetus is a very catholic western idea, and isn't always the same in eastern countires]. The issue in many Asian countries is purposefully targeting the unborn just for being female to be eliminated. I know a few countries had to make checking the sex of the baby before delivery illegal because of this.]
Bad female character or even annoying female character get killed or punished, men get away with it...just like real life. feel free to look any of the things I said, sorry to get all dark and serious. I agree with you 100% and its upsets me too. Looking up the bad treatment of woman and social views will explain the concepts you see in comics. Art imitates life and all that ~
Unfortunately their are lot of people that give the male character a free pass because they are "hot" or " feel sad uwu". I had a conversation with one of these types before and its really infuriating how they can excuse abuse so much.
