Yu Miaomiao has loved Mo Chen for over twenty years, only to discover he loves her sister Yu Xiaoxiao. Ecstatic at first when engaged, she falls into a nightmare. They marry, but Xiaoxiao suffers a car accident and becomes comatose. Framed and betrayed by Xiaoxiao, Miaomiao is imprisoned for five years. After release, she seeks divorce—but Mo Chen refuses. He forces her to kneel by Xiaoxiao’s bedside, berating her. Under Xiaoxiao’s manipulation, Miaomiao endures abuse, a miscarriage, and eventually gives birth to a son—only to be betrayed again when Mo Chen donates Miaomiao’s kidney to Xiaoxiao. As Xiaoxiao awakens, Miaomiao fakes her death and escapes. However, Mo Chen eventually finds her again.
