Prince Xiao of Nanyao is extremely beautiful but ruthless. Because his mother is not favored and his mother's family is weak, he has been suppressed by his father since he was a child, and he is trapped in the quagmire of seizing the rightful son.
He is well versed in maneuvering and regards everything as a pawn, including Beichen's proton Duan Wuhao. Duan Wuyang has been dormant in the deep palace of Nanyao for seven years. Xiao Dexin is the only glimmer of light in his desperate situation. This secret love has long been seen through by Xiao Dexin.
Xiao decided to use her beauty to release ambiguity intentionally or unintentionally, teasing and suppressing, arousing Duan Wushu's shame and obsession, just to hold this chess piece firmly in his hands and help him clear the obstacles such as the second prince and the sixth prince, and ascend to the throne of emperor.
Later, Duan Wuyang returned to the country to quell the civil strife and ascended the throne as emperor. The two emperors stood side by side and the north and the south faced each other. The past use and being used, love and calculation, were repeatedly pulled in the chess game of power.
Xiao Decide is still cold and ruthless, insisting on controlling everything; Duan Wuyao sheds his humbleness and hides his deep feelings, but can never forget the past.
A sadomasochistic relationship with power as its bones and obsession as its soul was endless in the flames of the two palaces.
Intention: Under power, obsession is hard to break, and love is just a bargaining chip in the chess game.
