Her name is Yan, no surname! No father! No mother! There is only one sister who I bought with my life, Su Yu!
She loves Yuyu, but Yuyu hates her!
My mother hates her because she is not the child she wanted, and my sister hates her because she is a scoundrel! Yuyu hates her because her mother destroyed the Su family!
So, just accept it and become an unintentional puppet, without love, hatred or intention! Become a murder tool in your mother's hands!
