They said that Si Li's mother was a mistress whom everyone shouted at, who seduced Sheng Jinghuai's father and caused his mother to become a vegetative state.
Sheng Jinghuai hated her for seven years. He threatened Si Li with his child and worked as the humblest servant in the Sheng family while watching him fall in love with other women.
He said: "Si Li, you ruined my family! I will never let you go in this life!"
Si Li accepted his fate and stopped resisting, letting the vicious dog he brought bite him.
Later, when Sheng Jinghuai found out that those things had nothing to do with Si Li, he went completely crazy looking at the pool of blood.
