He Xiang, an ordinary-looking girl who was born as a geisha, deeply captured the heart of Zhan Ling, the prince of the Northern Kingdom, with her soft-scented ecstasy dance. After her mother passed away, He Xiang, who was alone, accidentally became the maidservant of Li Yunfei, the prime minister of the Northern Kingdom. The overbearing Miss Yunfei was very proud of her status as the future princess. She was afraid that Hexiang would take away her title of the Northern Dance Queen, so she strictly demanded that Hexiang not be allowed to learn dance. But Hexiang still practices dance secretly in private, and the natural dancer makes Hexiang shine dazzlingly. Zhan Ling, Li Yunfei's fiancé, was cold and indifferent to her, but he fell in love with the maid He Xiang. Zhan Yu, the second prince of Zhan Ling's children, fell in love at first sight with the beautiful and arrogant Yun Fei, but he was helpless. Hexiang felt inferior because of her low status and did not dare to face the prince's feelings. The emotional frustration made Zhan Ling gradually lose interest in governing, and the Emperor of the Northern Kingdom threatened to depose the crown prince. In desperation, Hexiang left the North Country and planned to go to the South Country to find her biological father whom she had never met. Li Yunfei was jealous and secretly sent a killer to assassinate He Xiang. By chance, Xuanyuan Feng, the son of General Jingyuan of the Southern Kingdom, rescued He Xiang at a critical moment of life and death. The general's wife has no daughters, so He Xiang is an adopted daughter, and He Xiang is promoted from a maid to a young lady. Getting along day by day made Xuanyuan Feng fall in love with the kind-hearted He Xiang. He Xiang still couldn't forget the prince who asked her to dance for him for the rest of her life, so she refused cruelly. Ling Meng, the princess of the Southern Kingdom who deeply loves Xuanyuan Feng, uses special means to confine He Xiang to the Southern harem due to jealousy and hatred. In the backyard of the deep palace, Hexiang became particularly peaceful and danced all day long. The emperor of the Southern Kingdom was inadvertently attracted by the lotus fragrance dance, and the man he missed every day seemed to appear again. The token in He Xiang's hand proves that she is the illegitimate daughter he gave birth to to the famous singing prostitute He Yao when he traveled to the Northern Kingdom when he was still a prince. He Xiang transformed from the illegitimate daughter of a singing prostitute into Ling Xiang, the princess of the Southern Kingdom. Two years later, the Northern Kingdom sent envoys to marry the Southern Kingdom and ask for the princess to be their queen. Hexiang went there voluntarily because of concerns in her heart. A marriage has been successfully completed, and the only word of love is "will you dance for me for the rest of your life"?
