- Rakan loved her, but didn't have enough money to purchase, while getting her pregnant to lower value wouldn't be possible unless the woman herself wanted it deliberately (because contraception existed). So Maomao's mom was his accomplice, or rather, she was the main culprit.
- Before Rakan knew about her pregnancy, his family sent him away to a remote region. Letters from her was cut off so he didn't know until a few years later.
- Momma lost her value as top courtesan and had to take rag-tag customers. One of them infected her with syphilis. The disease, coupled with lack of contact from Rakan gradually deteriorate her mentality, at one point she even tried to cut Maomao's finger to send it with letter to Rakan.
- When Rakan came back and found out about that, he was furious. Dude overthrew his dad, took over the family.
- He wanted to buy Momma and Maomao out, but the Madam angrily banned him from entering the place (just got unban recently, but Maomao has already been purchased by Jinshi).
- Generally the people at Rokushoukan knew that he isn't a bad dude, even the old hag tried to push Maomao becoming courtesan so he could buy her.
And Maomao understands her parents' circumstance. She just hates him for being creepy-ass, like a daughter in rebellious phase (though that phase has lasted for decade).
