Yun Tang was adopted by the Yun family as an adopted daughter when she was three and a half years old. For twenty years, she has been keeping her role as an adopted daughter. She does not reject the sudden appearance of a real daughter, and even the adoptive parents are happy to finally find their biological daughter. However, Yun Tang gradually discovered that the real daughter did not seem to be the real daughter. The real daughter was still living a life worse than death in that small mountain village.
The conspiracy of the fake daughter was discovered step by step, and her parents and brothers stood behind Yun Tang, waiting for the return of the real daughter.
Yun Tang and the real daughter got along very well, but on the wedding day, the real daughter actually fainted her and replaced her as the bride at the wedding.
