In the Song Dynasty, Ximen Qing (played by Lin Weijian), a member of a prestigious family, is handsome and gifted from birth. He also inherits his father's (played by Xu Shaoqiang) medical skills and pharmacological knowledge, excelling in yang replenishment techniques. Just as he is coming into his own, his father hires a charming courtesan (played by Kaera Uehara) to stay at their home. Officially, she is presented as a daughter of an old friend temporarily residing at the Ximen household, but in reality, she is arranged by his father to seduce and guide Ximen Qing in the art of lovemaking and the skills of dominating women. She teaches him that in matters of love and pleasure, one must avoid giving their heart and instead prioritize self-protection through manipulation. From this point on, Ximen Qing's life is set on a path of womanizing and conquest.
