Food delivery worker Li Xiang accidentally encounters a little imperial princess who time-traveled from an ancient dynasty. An ancient copper coin connecting the two realms builds a wondrous bridge for round-trip travel between ancient and modern times. Delicious modern foods and novel technology amaze the entire ancient imperial palace, letting emperors, imperial concubines, and the royal family glimpse a entirely new world. A gentle and healing trans-time bond begins here, as Li Xiang carefully guards the little guest who came from afar, leading the royal family to experience modern life and broaden their horizons. Everyone moves toward each other and heals one another, not only unlocking countless interesting daily moments, but also breaking stale perceptions and rewriting destined fates, weaving a warm, healing tale of cross-time mutual growth.
