"Mira, you are the true Saint." —So says Prince Al, smiling gently. But… I'm only pretending to be a Saint for the sake of revenge! Once falsely accused and executed, Mira is reincarnated as a princess of a neighboring kingdom. However, her peaceful life is short-lived—an invasion by the enemy nation claims her homeland and parents, and she becomes separated from her brother.

When magical beasts suddenly attack, Mira's unique abilities awaken! Mistaking her for a Saint, Alphaus strongly insists on bringing her to the royal palace... "If pretending to be a Saint is what it takes to find my family and get revenge on that kingdom… then so be it!" Thus begins Mira's undercover life in the palace, hiding her true identity. But little does she know—Alphaus’s first love was none other than her from her previous life… the very Mira who was executed! A reincarnation × revenge romantic fantasy where fate intertwines across time!
