In her stead, a girl named Liz, who looks remarkably similar to her, was hired as her double and lives a dazzling life under the sun, while Leticia spends her days doing menial tasks in the shadows. But one day, Leticia receives a marriage proposal from the crown prince of a neighboring nation because the birthmark she carries matches a divine revelation. When the time for her wedding arrives, Leticia’s eyes light up as she sees the outside world for the very first time… until Liz, driven by envy, schemes to steal the role of bride for herself! With her life in danger and nowhere left to turn, Leticia is saved by a mysterious mage who seems to carry secrets of his own?!
