In the Chu Dynasty, the new emperor Rong Jingyuan has been on the throne for three years. On the surface, he is a wise emperor who is as gentle as jade and courteous to his subordinates. In fact, he is at every step in the power struggle and plays with all the forces at his fingertips. The heroine, Su Qingwu, was originally the daughter of a general who ruled the country. She was taken into the harem by Rong Jingyuan due to a sudden glance at a palace banquet. She seemed to be coquettish, spoiled and arrogant, but in fact she was pure at heart and gave all her sincerity to Rong Jingyuan. However, the love between the two fell into a whirlpool of intrigue from the beginning. Rong Jingyuan initially approached her to check and balance the general of the country, but gradually fell into love with her while they got along. However, Su Qingwu gradually became discouraged due to misunderstanding and injury, and the sadomasochism began.
