Lee Kangplayed by Kang Tae-Ohis heir to the throne. Beneath his free-spirited, uncontrollable exterior lies a deep-seated pain: that of a lost love, sacrificed on the altar of palace political rivalries. Silent but determined, he carries the burden of succession alone, while secretly dreaming of the day when he can exact his revenge.

On his side, Park Dal-yiperformed by Kim Se-jeonglives a very different life. A shrewd merchant, talkative and persuasive, she has a knack for selling anything to anyone. Behind her confident smile, however, she hides fragments of lost memory, remnants of a past she doesn't fully understand.

But one day, a supernatural event turns their lives upside down: their souls exchange bodies. From then on, each must learn to survive in the other's life, he in the tumult of the people, she in the arcanes of royal power, with all that this implies in terms of misunderstandings, revelations... and unexpected feelings.
