A revolutionary romance of body-swapping chaos between a fleeing bandit and the Grand Prince determined to catch her! By day, Eun-jo lives a quiet life as the illegitimate daughter of Minister Hong and a physician at the Hyeminseo. But by night, she transforms into Gildong, the legendary "Righteous Thief."

Her smooth criminal career hits a snag when the Grand Prince—second in line to the throne—tumbles into her life, bringing with him a series of "lovely" complications. Lee Yeol (Grand Prince Dowol), the King's only brother and the self-proclaimed "Greatest Detective in Joseon," falls head over heels for Eun-jo the moment they meet. He pursues her relentlessly, completely unaware that the woman of his dreams is the very bandit he has sworn to capture! Walls of social status and conflicting beliefs stand between them, yet their feelings only grow deeper. But just as tensions peak, a sudden twist of fate causes their souls to switch bodies! What starts as chaos soon evolves into a grand ambition to overturn the nation itself. Oh, my beloved bandit... will we ever be able to love in peace?
