Deep in the palace and with high walls, the queen and the concubine stand side by side with honor. As the legitimate daughters of two aristocratic families, they have been tit-for-tat enemies since entering the palace.
For several years, the two were deeply involved in harem disputes, competing with each other for power and favor, but neither could escape the dilemma of having no heirs for a long time. Strange physical conditions linger around him, and it is still difficult to find out the mastermind in the dark. Suspicious cases occur one after another, and concubines from all sides become objects of suspicion one after another.
The turmoil did not stop at the harem and the court. The family power was frequently suppressed and framed for unknown reasons. Under layers of fog, the two people who used to be antagonistic gradually realized that something was wrong. When all the clues point to an unexpected person, the former sworn enemy puts down the barriers, and there is only a bone-chilling chill in his eyes.
The chess game in the harem has been secretly manipulated for a long time. The real wolf is hiding on the throne, and a joint game that subverts the court situation begins.
