The ancient scholar Su Wan accidentally traveled through time while repairing a "Ningshuang Palace Costume" from the Ming Dynasty, and became a minor promise in the harem of the Dayong Dynasty. With the help of modern knowledge, she managed every step in the dangerous palace, and even got acquainted with the seventh prince Xiao Jingyuan.
In order to find out the unjust case of his mother and concubine, Xiao Jingyuan formed an alliance with the clever Su Wan. During their shared adventure, the two became deeply in love. However, Su Wan always carries a secret - she does not belong to this era. When the secret of Ningshuang Palace Dress is revealed and the time and space passage is opened again, she must make a choice between her modern parents and her ancient lover.
What is even more unexpected is that this palace costume actually involves a fate that spans six hundred years. The early prophecies of Princess Duanhui and the appearance of the mysterious professor Zhao Mingyuan all indicate that this time travel is not accidental. When Xiao Jingyuan was willing to give up the throne for her and travel through time and space, when the modern and ancient worlds intertwined, a legendary love spanning time and space began.
This is a choice about love and family, responsibility and freedom. It is also a touching story of a modern woman searching for her true self between two time and space.
