People also need to read the whole book. The problem with this book is that all the plots are driven by drugging. The way the highly intelligent villain wants to beat the heroine is to push someone into the water, so that her identity is exposed.
The temptation of changing gender and returning home? I can't count it. It's just about seducing a mistress. It's just about gender change. It's a revenge story about the villain's family once killing the heroine's mother. Maybe I don't feel that switching genders is very satisfying. I can only say that I can't love this book at all, especially the part where the villain once got pregnant and had a miscarriage. I didn't feel any satisfaction at all.
Every male protagonist is crazy and relies on madness to retain the female protagonist. The problem is that he doesn't treat the female protagonist well either. He is hysterical throughout the whole process and presses the female protagonist. I was really tired at the end.
