The eldest young master of the Yao family died mysteriously while doing business, and was replaced by a man from the palace. With an unspeakable mission, what is his purpose of living anonymously in the Yao Mansion? His simple words, "The eldest lady is slow, the second lady is weak, and the third lady is too energetic" actually pushed the three rich ladies of the Yao family into different fates. The third young lady of the Yao Mansion, whom he had spoken so much of, was worthy of her "praising", and was sent as a chess piece to serve beside the weak and cowardly puppet prince in the palace. The third lady is submissive on the surface, but secretly deals with it, and joins forces with the puppet prince to confront him. Who is the man in the palace with blood-stained hands? Is the weak and incompetent prince really as good as he seems? Can the third lady escape the fate of the chess piece, save the lives of the Yao family, and bring to light the truth about the death of the young master of the Yao family?
