During the Yong'an period of the fictional dynasty, the imperial power was divided and undercurrents surged in the palace. He was the seventh prince who was neglected by his father and regarded as idle by the government and the public. After his wedding, he fell into a dilemma woven by the Queen Mother herself. Underneath the peaceful relationship between mother-in-law and daughter-in-law, there are constant temptations and calculations - the Queen Mother interferes in his marriage at every turn and makes things difficult for his wife. It seems that the elders in the harem are harsh to the younger ones, but in fact, it hides her coveting of imperial power and her obsession with past cases.
In the palace, strange events happened one after another: the maid responsible for taking care of the Queen Mother drowned in the imperial garden pond late at night, and half a strange jade ornament was left next to the body; a poisonous needle appeared inexplicably in the greeting ceremony prepared by the Crown Princess, pointing the finger at the unpopular him; the old men involved in the case of deposing the Crown Prince ten years ago disappeared one after another, but the clues were repeatedly interrupted in the Queen Mother's Palace.
He seems to be indifferent to worldly affairs, but in fact he is very thoughtful and has long been aware of the shocking conspiracy behind the dispute between mother-in-law and daughter-in-law. On the one hand, he has to deal with the Queen Mother's overt and covert attacks, and balance the relationship between the harem to protect himself; on the other hand, he has to secretly investigate the truth of the strange events and uncover the manipulators behind the scenes; he must also beware of other princes' eager eyes and the secret game of the family's power.
