Stand-In Trickster

There have been several deaths in Xuelin University where older student Wu Xiaobai lives. She protects Sir Huang, whom she has regarded as her father since she was a child, and while investigating a death case in school, she meets a student at the same school, the illegitimate daughter Wu Xueru. Just when she told Wu Xueru that she wanted to join the upper class society and her friendship with Wu Xueru gradually deepened, Wu Xueru committed suicide in front of her and replaced her identity with Xiaobai with a mysterious suicide note. When Xiao Bai was brought into her new home, she found that all her family members seemed to have been replaced. Except for Xiao Bai, she was very afraid of other family members. The family enthusiastically invites Xiao Bai to visit their own homes. Every time he arrives at a new home, Xiao Bai will forget the memory of being a guest in the previous family. It wasn't until Liu Mengyang suddenly broke into her "guest" life that the secret behind it gradually surfaced... All of this was a trap carefully woven for her.
