In a world where humans and dragons coexist, dragonkind—though capable of taking human form—are inherently violent and must rely on the magic of human women to suppress their frenzy. To secure power and compete for the throne, Dragon Lord candidates enter marriage pacts with women from powerful magical families. Anastasia, born into one such family and gifted with immense magic, once devoted her life to helping her husband Dmitri rise to the throne—only to be betrayed by him and her own sister, and die a tragic death in prison. On the brink of death, she casts a forbidden spell and is reborn on the eve of his proposal. This time, she refuses to be a pawn—she will rewrite her fate and take revenge on those who destroyed her.
