In the Great Qi Dynasty, an old child-swapping secret entangled the fates of three girls born on the same day: one from the Duke of Yongguo's household, one from the Marquis of Anping's household, and one from the Zhao family in Luozicun.
The poised and quiet Zhao Yuan should have been the apple of the Marquis of Anping's eye, but she grew up in the duke's household. Lively and spirited Le'an spent thirteen years as the marquis's second daughter, though she was actually a farmer's child. Timid Zhao Yun was brought back from the countryside to the duke's household, only to learn that she was its true legitimate daughter.
The day their identities came to light, none of the three girls was at fault, yet each had to learn how to live all over again.
Crown Prince Xiao Yanchen told Zhao Yuan, "Whether you're Li Zhaoyuan or Wen Zhaoyuan, I only want you." Li Jingzhao went from "I only see you as a younger sister" to riding thirty li to chase her to the estate, awkwardly learning how to hold someone dear. Ling Xiaoyuan said nothing; he simply bought the house next door to the Duke of Yongguo's residence and left a packet of osmanthus cakes beneath the wall.
Three girls, three happy matches. Their births had been switched, but their hearts were true.
