Ivy, the southern princess, was once trapped in a cruel fate: after marrying Duke Lucien, she spent five years imprisoned as he called out Rosa's name. When she dies and is reborn, she learns what awaits her on the wedding day—a stepmother's plot that trades her face with Rosa's and sends her to the north in place of the cursed bride. There, King Rex stands feared as a dragon-cursed ruler who kills his bride. Knowing the past she lived through, Ivy chooses differently and takes Rex's hand.
