In the autumn of 1979, Meng Xue awakens in a bridal chamber on her wedding day, realizing she has been reborn to the moment before her tragic past life. In her previous existence, she was drugged by her fiancé, Xi Mu Nian, and her cousin, Meng Ning, who orchestrated her fall from grace. Stripped of her virtue before the wedding, Meng Xue was branded a bringer of bad luck by the Xi family. After the death of the family patriarch, she was neglected and eventually tortured to death by the very people she trusted. Upon regaining consciousness, Meng Xue recognizes the effects of the drug and flees the bridal room, stumbling into the arms of Xi Jingchen, the uncle of her intended groom and a disciplined soldier.
Desperate to survive and change her fate, Meng Xue confesses that she has been drugged and begs Xi Jingchen for help. Despite his initial hesitation due to military discipline and familial ties, he yields to her pleas, and they spend the night together. Meng Xue then orchestrates a public confrontation, leading Xi Jingchen and family elders to discover Xi Mu Nian and Meng Ning in an intimate embrace. The scandal forces the Xi family patriarch, Xi Zhenhua, to intervene. Xi Mu Nian openly declares his love for Meng Ning and claims she is pregnant, demanding the cancellation of his engagement to Meng Xue. Meng Ning’s pregnancy is a fabrication designed to secure her position within the wealthy Xi family.
Faced with the disgrace, the family decides to proceed with a wedding but switches the bride. Xi Mu Nian marries Meng Ning, while Meng Xue is left without a husband. However, Xi Jingchen, having slept with Meng Xue, feels a sense of responsibility and proposes that they marry. Meng Xue, no longer in love with Xi Mu Nian and seeking independence, agrees but insists on a period of courtship rather than an immediate union. She retrieves a medal left by her deceased father, which Meng Ning covets, and secures it for herself. Meng Ning, also reborn, suspects Meng Xue may share her secret but is unable to confirm it.
As Meng Xue and Xi Jingchen navigate their new relationship, he provides her with financial support, which she uses to purchase study materials in preparation for the resumption of the college entrance examination. Meng Xue resolves to leave the Xi family and build a future based on her own merits. Meanwhile, Xi Mu Nian and Meng Ning’s marriage is fraught with underlying tensions, as Meng Ning worries about her exploitative parents discovering her new status. The story follows Meng Xue’s transformation from a victim of betrayal to an independent woman, as she aligns herself with the steadfast Xi Jingchen while outmaneuvering her vengeful cousin and regretful former fiancé.
