Set during the Joseon Dynasty, the story follows Ok Tae-young, a woman who has built a reputation as a highly respected legal expert and a pillar of her community. However, her entire existence is a carefully constructed fabrication; she is actually a runaway slave who assumed the identity of a noblewoman to escape her past. As she navigates the treacherous social hierarchy of the era, she must constantly outmaneuver those who seek to expose her true origins. The conflict intensifies when she crosses paths with Cheon Seung-hwi, a charismatic storyteller who travels the country and falls deeply in love with her. As their relationship deepens, the pressure of maintaining her double life becomes increasingly perilous. The series explores themes of identity, the rigid class structure of Joseon society, and the lengths one will go to for survival and love in a world that demands absolute conformity.
