I read the machine-translated version, and honestly, I found FL's character portrayal a bit annoying at the start. She came across as quite harsh, constantly shouting and screaming. I can empathize with her frustrations and the lack of guidance she faced, but it would've been more dignified if she'd handled her ex's issues with a bit more composure. Sigh, her anger seemed to get the better of her.
Despite that initial annoyance, if you can overlook it and just immerse yourself in the story, it's decent enough. I'd place it around the middle to lower end of the 1970s genre spectrum.
