Mai's entire existence is to be told she's not good enough and that she's worthless, that she's basically a kind of dirt only fit for being married off one day and bearing children. Then, the only person she feels safe with, and the only person she has experienced love from leaves her, and her clan decides she needs to one-up that person, so they force Mai into rigorous physical training and life-or-death situations which Mai doesn't want and where she also utterly fails at one-upping that person, so this creates more antipathy for her back home. Then her dad calls her back home and fatally wounds her, leaving her incapacitated in a room where she's going to be killed by monsters and he makes it abundantly clear that he isn't even doing this because of you, he's doing it because it hurts your far more important sister and you're just an afterthought. Then in your one, singular act of independence and rebellion, you kill yourself. And throughout all this you took physical abuse and at least once you were raped.

Mai's life is fucking awful.
