In her previous life, Su Qingyuan married Ling Mochen, the second young master of the Ling family. They were a brilliant academic couple in front of them, but later they became his tool for stealing achievements, and they eventually fell to their deaths; The stepsister Su Yuran married the eldest son Ling Yanzhou, but her husband took Bai Yueguang away and stayed alone in the empty boudoir.

Once the sisters were reborn, Su Yuran rushed to marry Ling Mochen, trying to recreate Su Qingyuan's past life, but she didn't know that she was stepping into the same control trap and became cannon fodder for her. The contractual marriage between Su Qingyuan and Ling Yanzhou was about each getting what he wanted, but when the trap came, he protected her: "My wife is not the turn of others to comment on."
