During the Wei and Jin dynasties, the Yuwen clan wielded considerable influence at court because their eldest daughter had become empress. After the emperor's death, Empress Yuwen held even greater power over the court. The clan had three sons: the eldest, Yuwen Xiaofeng; the second, Yuwen Changfeng; and the youngest, Yuwen Yifeng. By chance, Yuwen Changfeng fell in love with Xiyue, a noblewoman, but her heart already belonged to the hero Yun Feiyang. Out of maternal love for her son, Yuwen Changfeng's mother, the Grand Princess, asked the empress to arrange the match. Yet the couple's romance remained fraught with twists and turns. In the sprawling Yuwen residence, every match and every person hides an unspeakable secret. Everyone is caught in the whirlpool of power and status, where love and hatred are born, and where they meet their end.
