The deep palace is like a chess game, and human lives are the pawns. Li Lanyue, the proton of the Qing Kingdom, is trapped in the prison of the Cheng Kingdom. He appears to be meek and tolerant, but in fact he hides a sharp blade for revenge. He suspects that there is a hidden reason behind the death of the princess who grew up to be a kingdom, and that the mastermind behind the scenes is the powerful queen. In order to find out the truth and subvert the chess game, he deliberately approached the queen's favorite daughter, Song Yuhui, the innocent and romantic princess of Chengguo, and regarded her as the key to breaking the game.
However, the care of the cold night, the protection of the palace banquet and the unprotected trust under the moon, made this carefully laid out chess piece quietly turn into a light that illuminated his gloomy heart. When utilization and sincerity are intertwined, and when the revenge plan encounters an unexpected heartbeat, Li Lanyue falls into a dilemma. At the same time, the queen's fear, the second prince Song Ce's temptation, the prime minister's eldest son Lin Zhanjing's affectionate pursuit, and the Qing Kingdom's ready-to-move cavalry drew the two into a deeper whirlpool of power.
