A devastating fire destroyed everything the legitimate daughter had. Three years later, wearing an unfamiliar face, she returns to the capital and enters her former home under the guise of a musical performer. An old hairpin, a list of names, and a long-buried case—she carefully sets her traps, bringing every wrongdoer from that fateful year into the light, one by one. She has returned for one reason only: to reclaim justice. This time, the injustice will be overturned, and good and evil will each receive their due.
