After being abandoned by her family, a noblewoman takes her own life and becomes a vengeful spirit. After exacting revenge, she seeks her past-life lover and encounters Charlotte, a girl similarly wronged by her family. Forming a pact, the spirit is reborn through Charlotte’s sacrifice. Learning of the injustices Charlotte suffered—framed by a fake heiress, neglected by her biological parents, and betrayed by her brother—she vows revenge once more. Using her supernatural powers and with the help of her reincarnated lover, she exposes the family’s hypocrisy, makes them regret their cruelty, and ultimately finds justice, love, and happiness.
