Su Yao accidentally became the substitute of Gu Chenzhou, the young marshal of the Gu Group, and was placed in Gu's house to fill the vacancy of Lin Yue. When Lin Yue returned from overseas and vowed to regain her lover, Su Yao not only accompanied Gu Chenzhou to resolve the company crisis with tenacity, but also quietly opened his frozen heart. However, the Lin Yue family intervened with the last wish of "being forced to leave", and Su Yao insisted on "not giving up" in the bitterness; Lin Yue returned after many years of success, thinking that the substitute would eventually give way, but witnessed Gu Chenzhou protecting Su Yao behind him - this sadomasochism that spanned the substitute and Bai Yueguang finally led to the redemption of reunion in the plea of "give another chance".
