One is an emperor with a deep heart, and the other is a noble lady from Kyoto who just wants to protect her family's safety.
At the beginning of the story, she is a beautiful chess piece on his chessboard. She is docile, decent and blameless, and is the best "hostage" and "comfort". He watched with cold eyes, waiting to see whether this famous daughter of the Shen family would show her ambition fangs or wither away in the harem fight.
In order to protect the safety of her father and brother, as well as the safety of the whole clan, she put aside all her sharp edges and voluntarily stepped into the nine-layered palace, becoming a pawn for the emperor to balance the court. All he wants is the word "stability", to find a glimmer of hope for the family amid the strife between the emperor's intentions and the harem.
At the top of the palace, they used the world as their chess and their sincerity as their bet. From games to getting to know each other, from suspicion, temptation, appreciation to deep love, this is not a unilateral redemption, but a mutual illumination and mutual achievement.
