She wasn’t a terrible friend or really rude she just didn’t baby Hachi. She would give her a reality check unlike everyone around her. Also, this is the early 2000s people were very straight up and did not care to hurt anyone’s feelings it was just like that back then
Like I said, if you care about your friend that much why're you accomplice with the people who hurt her?
Because she wasn’t just close with her she was close friends with Shoji and he was really the only one who hurt her. Her victim blaming was the only thing she ever did wrong but the rest she was 100% right.
Other than victim blaming Hachi when shoji cheated on her everything else she did was totally reasonable and also was for the betterment of Hachi. Just one mistake doesn't make someone a horrible friend and a person.
I find Junko as a terrible friend. I'm not denying Nana wasn't healthy minded, but if you're gonna be rude to your friend anyway to toughen her up, maybe not be an accomplice with the people who hurt her?
Also despite how healthy Nana's family looks, Nana's behaviour is reflection of their ignorance
