On a rainy night, Mu Jinhe, the eldest daughter of the Mu family, and her son-in-law Zhou Jianguo welcomed the long-awaited arrival of their child. They named the baby Mu Weiyi, symbolizing the only heir to the Mu family's future. However, behind this joy lurked a well-hidden secret. Zhou Nian, Mu Jinhe's adopted daughter, fearing the loss of her mother's love, was consumed by jealousy. During Mu Jinhe's childbirth, she deliberately caused an accident, leading to Mu Jinhe's premature delivery and subsequent coma. Taking advantage of the situation, Zhou Nian stole the newborn Mu Weiyi, with the intention of monopolizing the Mu family's affection and wealth.
At the same time, Qin Shu, Zhou Jianguo's former lover who had been abandoned by him, unexpectedly learned the truth. In a fit of rage, she confronted Zhou Jianguo at his doorstep but was humiliated and driven out. Qin Shu discovered that her biological daughter, Zhou Nian, had become the adopted daughter of the Mu family, and that Zhou Jianguo had been using her daughter as a means to solidify his position. In a state of despair, Qin Shu was determined to reclaim her daughter and exact revenge on Zhou Jianguo.
In the midst of the rainy night, Qin Shu, holding the discarded Mu Weiyi, whom Zhou Nian had left behind, wandered the streets, ready to abandon the baby as an act of vengeance. However, at a critical moment, Qin Laotai, Qin Shu's mother, appeared and stopped her from carrying out this irrational act. She took Qin Shu and the baby home. Under her mother's consolation, Qin Shu regained her composure and decided to make Mu Weiyi a part of her revenge plan. At the same time, she also aimed to pave a different path for her own daughter, Zhou Nian.
From then on, using Qin Shian (Mu Weiyi's new name) as a link, Qin Shu secretly plotted. She was determined not only to expose Zhou Jianguo's true nature but also to assist Zhou Nian in seizing the position of the Mu family's heir. In this tangled web of family feuds and personal grudges, the fates of Qin Shu, Qin Shian, and Zhou Nian became closely intertwined, jointly writing a story about love, hatred, growth, and redemption.
