I'm a bit sick of these kinds of shallow criticisms of women/female characters... I mean for one thing she got groomed by an older dude when she was underage, for another women do not become dismissable or fundamentally unlikeable cuz they commit the crime of not being Strong Independent Girlbosses. Women are allowed to want marriage and family and society is constantly telling them that's what they should want regardless of whether the guy is a selfish abusive jerk or not (as tbh most of the men in Nana, and a disturbing number of the men I've encountered in reality are, and before someone responds by saying women can be bad people too I'm not arguing they can't, but Nana Komatsu isn't a bad person.) I don't put masses of stock in things like MBTI but it's worth noting that she's theorised to be the same type as Tohru Honda from Fruits Basket and it shows, it's just that in the universe she's in there's a lot more reason to be skeptical of people in some ways (as in, Tohru's mum tells her it's easy to doubt so try to be someone who can believe in people, an admirable sentiment but Nana is partly a critique of compulsory heterosexuality and the way men often behave towards their female partners). Speaking as someone who has been a 20 year old (disabled) woman and a rather vulnerable one at that, I could very easily have ended up with a horrible scumbag of a man because I had zero self-esteem pretty much, and I really, really feel for Nana K (I like Nana Ozaki too, for the record, but she doesn't earn any extra favour for me for needing others perhaps less than Nana K does, and speaking as a disabled woman I am continually wary of how people view me in light of how they seem to view women like Hachi).
