Because Chinese people look up on the child's background (a bastard especially from unknown man is much lower than a legal child) and gender. That's is why it is questionable if it's not about the gender or background, why would she loves one that deserves love? If she hates the husband, don't hate the child. If you want to cut him out of your life, make it clear, don't leave a way for him to connect with you if he ever escape.
I think that his mother took only his sister with him cause she's a girl and maybe can only take one child with her or whatever reason because men in that village are sick and disgusting so her daughter was a better choice to take with her but it is still so wrong and makes my blood boil that pig of man from that village also graped him
And original body memories coming back to him was because ML forced him and it just triggered the old owner memories
Mostly the community treated them just like a mistress being treated. It's the same with the people outside the Chinese community. Especially the older generations, child out of wedlock especially from unknown father/mother, treated unfairly. However in THIS PARTICULAR STORY, she just outright abandoned him but leaving a way to connect with her only to abandon him AGAIN and choose to be with the daughter.
The original body Mother ..the child did nothing wrong. You left him, but you brought your daughter, who comes from a wild bastard, for a better life, while you despise your son, whom you got through marriage. Double standards are real. If you hate your son , you should hate your daughter too.
