Was Yun Xi the heroine in He Shu?

I recommend "The Crown Prince of the Prosperous Age, Please Marry", an ancient romance novel. It tells the story of the noble status of the Princess of Xia Country, but no one knows about it. Her father is cold and heartless, the Imperial Concubine is ruthless, the Imperial Sister is sharp and vicious, and the Imperial Brother wants to seize the position of Crown Prince. The prince of the Chu Country had the appearance of a celestial being and was rich in worldly talent. His temperament was indifferent and unparalleled in the world. When he met her, was he a sheep entering the tiger's mouth or a strong team? He had used the country as a betrothal gift to marry a beautiful woman, but it was to say to her,"Yunxi, from now on, I will protect you…" I hope you like this fairy's recommendation. Muah ~😗
