Ye Yi'an, the heiress of the Ye family, one of Yuncheng’s three great houses, was betrothed long ago to Li Mingxiu, the eldest son of the Li family, another of the three great houses. But Ye Yi'an discovered that Li Mingxiu had countless women on the side. By chance, she saved Li Yanxiu, an illegitimate son of the Li family. One wanted to become head of the Li family, while the other wanted to break off her engagement, so they joined forces… After spending time together, they fell in love, and at last their engagement day arrived. But a scheming woman had Li Yanxiu’s mother killed and framed Ye Yi'an. Ye Yi'an’s parents were also framed and killed by a collateral branch of the family, and the two were torn apart. Three years later, they met again… “Ye Yi'an, from now on, you’ll stay by my side and atone for my mother’s death.”
