Minori is pretty and popular, lives in a beautiful wealthy country, earns enough money with a relaxed job, has good friends, gets supported by her family, and so forth but she is so angry, having ugly fights with assholes, even with family & friends. Why?

Ok, she was abused by her father, but it was a long time ago, so why doesn't she makes her own family and find peace, like Sachi in 'Our Little Sisters' (2015), like many other characters in J-doramas and movies?

The thing is this: She has a social awareness, so it's not only about her father's abuse, it's about everyday abuse and discrimination. She's well aware of the dark side of her beautiful country:

I just hope instead of ugly useless personal fights, she'll find angry women and men like herself, so collectively fight for social change.
