The wealthy Lu family gave birth to twin daughters twenty years ago. Due to internal fighting, sister Shen Xingwan was maliciously abandoned in an orphanage, while sister Lu Yao grew up as the sole heir. When he became an adult, Lu Yanzhou (the male protagonist)'s younger brother died unexpectedly, and the investigation clues actually pointed to Shen Xingwan, who was struggling at the bottom. Lu Yanzhou approached Shen Xingwan as an "investigator", but was gradually attracted by her tenacious soul. In order to find out the truth about his life experience and take revenge, Shen Xingwan entered the Lu family and had a head-on confrontation with his "sister" Lu Yao. As the truth unfolded, they discovered that the exchange was actually planned by Lu Yao's biological mother for revenge, and Lu Yanzhou's family was also deeply involved. In the end, Shen Xingwan regained everything that belonged to him, and Lu Yanzhou made a choice between family and true love. The two teamed up to expose and smash the revenge conspiracy that lasted for two generations, completing the redemption of self and destiny.
