Inside the Chinese imperial court, the stern Emperor Xiao Jinyun and the spirited Empress Xu Yu are in constant conflict. However, the universe resolves their issues in an unusual manner: an accident causes them to swap bodies, forcing them to literally step into each other's shoes. Now tasked with unfamiliar duties and court dynamics, the emperor and empress must manage the preservation of their identities, unruly concubines, and the nation itself. Through this process, Xiao Jinyun and Xu Yu's personal traits and unconventional skills find new application, fostering a sense of understanding and compassion between them. Nevertheless, significant threats loom both within and outside the court. If the imperial astrologer fails to find the key to reversing the switch in time, internal strife and suspicion may result in the duo's premature death.
