Shen Qingluan, the legitimate daughter of the Duke of Zhenguo, originally had a bright future, but was framed by her concubine and was forced to marry into the turbulent East Palace. At the same time, in order to protect his young brother Zhou Quan, Prince Jing of the North, Xiao Jue, resolutely decided to marry the daughter of the Duke on his behalf.
On the wedding night, the red candles were shining and the hijab was raised - two people who should not have met looked at each other. One is a down-to-earth legitimate daughter who was married as a substitute, and the other was a cold-faced prince who was married as a substitute. This misplaced marriage started with caution and testing.
At first, they were just a fake couple who each got what they wanted: she used his power to protect herself, and he used her to cover up others' eyes. However, the situation in the court is treacherous, and the undercurrent in the East Palace is turbulent. In the crisis confrontations and life and death battles, the two hearts quietly get closer. When the storm of power intrigues swept across, they chose to fight side by side, starting from Princess Jing and the Prince Regent, and working together step by step to reach the position of the Nine-Five-Five Greatest.
In the end, the emperor and empress honored each other and made a vow to "be together for the rest of their lives." This unexpected marriage turned out to be the most perfect marriage in the world.
