Ok I try to answer your questions to the best of my ability but please keep in mind these are only my impressions and speculations.
I don't think Maomao hates her father, she might resent him some, but she doesn't hate him, which she also states herself. She was traumatized by his appearance the first time they met, as he was dirty and bloody, and she was only a little girl. She also didn't know who he was at that point in time. More I don't know. Could be that she just doesn't like him, since she also mentions that he tried to make Maomao call him papa or father.
Second question: The reason why the mother tried to stab her, and I believe she didn't really want that she "only" cut off her pinky, was because the mother believed that she was abandoned by Rankan, as he told her he would be back in one year, but only came back three years later. It could be that she believed he abandoned her because she fell pregnant and had Maomao. Thus leading her to belive it was Maomao's fault. But as I mentioned, these are only my speculations. Hope I could help ^^
Exactly my thoughts, being raised in a red light district IS NOT NORMAL so it's expected of Maomao to be a certain way. Since young she was threatened to be pimped by that hag so it's only natural that she's cautious of everyone and has a sense of detachment. Her father's bloodied face and her mom's deteriorating state was the 1st thing her young mind has witnessed. Home environment shapes oneself fundamentally which is why she likes to not attach herself to anyone besides her grandpa that gave her the feel of "home".
Y’all please answer this. So I thought that Maomao’s mother was raped by maomao’s dad then died right. Come to find out he didn’t rape her and it was mutual. When other people find out her price went down and she had to do night services bc she wasn’t pure anymore right??? I don’t understand why maomao hates her father if she knows he’s innocent and everyone hates him too!!! Cause he seemed to really love her and was crying so I’m kind of lost Why did maomao’s mom tried to stab her like in the beginning of the story when she was just introduced as a patient
