Six years ago, Jiang Yu caught her husband, Prince Jing Heng, cheating with her best friend Chu Yao. After their divorce, she discovered she was pregnant and married her brother-in-law, Wen Yanqing, living a quiet but nominal marriage for six years. When Jing Heng becomes emperor, he regrets losing her and forces her back into the palace, even using her daughter Zhao’er to keep her close. Now Empress, Chu Yao persecutes Jiang Yu and her child out of jealousy, while Jing Heng—misled into thinking Jiang Yu loves Wen Yanqing—lashes out in pain and anger. Wen Yanqing tries to take Jiang Yu away, revealing his long-hidden feelings for her—but it’s already too late. As Jiang Yu prepares to escape, Jing Heng learns Zhao’er is actually his daughter and that the past betrayal was not what it seemed. Jiang Yu fakes her death and disappears. Jing Heng is left to live out his days in endless remorse—until two years later, they unexpectedly meet again in Jiangnan.
