The Substitute Bride: Ex-Husband, Let Me Go

The male protagonist was once the light in the heroine's miserable world, but he was deceived and began to abuse the heroine. In fact, we can't blame the male protagonist, because what he won was a loved one's dance, and it was a masterpiece that was carefully crafted for him by a group of relatives and friends who spent several years. Coupled with the fact that the female protagonist is in a very abnormal mental state, the heroine is really miserable in the front part, but she gets better in the back. In fact, there are some loopholes. For example, since the hero's father likes the heroine's mother, why didn't he help her and let her die in prison? And grandpa knows that the hero's mother is not a good person, why didn't he warn the hero earlier? The heroine's brother has been using pornographic literature to seduce the heroine's best friend. He thinks he is a yandere and crazy, but in fact he is greasy. Moreover, if he hadn't set fire to his sister in order to test the heroine's feelings, the hero would not have thrown the heroine into a deserted village, causing the heroine to almost die on the spot.

The author writes very well, but the first part is a bit rough. I suggest you read it patiently, it's really good!
