This is a chess game that begins with exploitation, and is also a gamble that pays off.
Yan Huayao, the most notorious eldest princess of Dayan, hides an ambition to stir up trouble under her ridiculous appearance. Xiao Heng, the hostage sent by Beichen, behind a docile and harmless mask, is burdened with an involuntary espionage mission.
One night, he was desperate and offered himself a pillow. She saw through it immediately, but accepted it happily.
From then on, the court became their chessboard and the world their chess pieces. He plotted people's hearts, and she used his strength to fight her way through the turbulent battle for the right to inherit the throne. Side by side on the blade, the cold exchange of interests breeds out-of-control emotions.
However, when his undercover identity came to light, the choices between family, country and true love, family ties and betrayal were placed before them. They made the craziest choice on the edge of the cliff - to abandon their old master and go to life or death together.
Later, she reached the pinnacle of power in Dayan, and he ended Beichen's half-life feud. The world is talking about the empress of Dayan, whose consort was once a hostage of an enemy country.
No one knew that in that chess game that the world was betting on, they had already given each other their only weakness.
