Summary
Cho Kyung, a modern forensic specialist, is inexplicably transported to the past. There, she trains under Master Jang, a disabled but brilliant coroner in Cheongsuhyeon, disguising herself as a man to fit into her new reality. To support herself, she takes work with the wealthy Jo family, but when her mentor dies under dubious circumstances, she becomes convinced it was murder. Determined to uncover the truth and seek justice, she crosses paths with the mysterious Lee Cheonso, who offers his assistance—but only if she agrees to help him with his own secret agenda.
