The heroine's true identity is an illegitimate daughter who was abandoned by her wealthy father. Her father used a conspiracy to annex her mother's company, causing her mother to become seriously depressed and ill. She infiltrated the Fu family as a "marriage substitute", but she was actually secretly investigating evidence that her father had colluded with members of the Fu family. The male protagonist Fu Yanshen appears to be cold and ruthless, but actually suffers from a severe emotional disorder. His first two wives were killed by ghosts in the family, and he only married Shen Nian to paralyze the ghosts. The two fell in love amidst interests and temptations, and faced sadistic choices in the mid-term of "their respective revenge plans conflicting with each other."
