Synopsis
During the Joseon Dynasty, Kang Dan-shim gains notoriety at court for her cunning and ambition. Through manipulation and intellect, she ascends to the rank of royal concubine. Feared for her ruthlessness, she is eventually sentenced to death by poison.
However, her fate does not end with her death. Her soul awakens in 21st-century South Korea, inhabiting the body of Shin Seo-ri, an unknown actress who plays minor roles in historical dramas. In this unfamiliar era, Dan-shim gradually takes control of Seo-ri's life and, due to her unpredictable nature, quickly adapts to the modern world. She crosses paths with Cha Se-gye, the ruthless chaebol heir. The two develop a tense, conflict-driven relationship complicated by a love-hate dynamic.
Navigating the unfamiliar world, Kang Dan-shim realizes this twist of fate gives her a chance to escape her predetermined destiny and reshape her life.
