Despite his exquisite, flower-like beauty, the male concubine Yeon Hwaun was loathed by the entire court for his vicious temperament and wicked deeds. On the day he plunged into the palace pond, a devoted guard perished while trying to save him. When Hwaun's eyes opened again, they held a different soul: the spirit of that fallen guard, Haun, now trapped within the despised concubine's body. Haun vows to the palace that the hated concubine has changed, but his pleas fall on deaf ears—no one believes a word. Emperor Yihan, whose deep-seated hatred for Hwaun burns hotter than anyone's, is utterly bewildered by the man who is the complete inverse of his predecessor. Unable to decipher the soul occupying Hwaun's perfect body, the Emperor's cold fury intensifies: "Insolent wretch... what malicious scheme are you weaving now? Fine. Let's see your grand performance; I will allow myself to be deceived... for now."
