Once reborn, she returned to her wedding night and saw Gu Rinchuan abandoning her for Wen Yaoyue again. In this life, she put aside her infatuation and worked step by step to seize the power of the housekeeper, planning to expose Wen Yaoyue's true face and make her suffer the consequences. She secretly supported Shen Yanjing, her former benefactor, to consolidate her position and launch ruthless revenge on Gu Linchuan, who was deeply regretful. After taking charge of Prince Rui's Mansion, Jiang Zhiling finally married the powerful Taifu Shen Yanjing and ushered in a happy life.
