Zhanyan's good friend Liang Yue's sister suffers from mental illness. Zhanyan's mother strongly opposed her daughter's continued relationship with Liang Yue, and Zhanyan was very sad. Zhanyan learned that Liang Yue's sister Liang Can was not a biological sister to Liang Yue, but a child abandoned by her aunt's family. Shortly after Liang Yue's family moved out, there was a fire at home and Liang Can disappeared. On a rainy night, Liang Can came to Zhan Yan's house and asked for Zhan Yan's help, saying that Liang Yue's parents were not good for her and that she was not a mental patient. Zhan Yan followed Liang Can to the former Liang family, but was pushed down from the window by Liang Can.
