A distant echo from a life long-forgotten; shattered shards of an ominous future. When her late mother's heirloom pendant is broken, Elodie Perdia regains the memories of Ga-eul Yun, a girl from our world who realizes she's landed in the body of a villainess from a fantasy novel. In the story, Elodie serves as the dark foil to the virtuous heroine and is destined for an early grave—a dark fate that can perhaps be avoided with Ga-eul's knowledge of future events!
