The Lady's Butler(2020)

Woori is heartbroken when she finds out that her favorite character Lancelot dies tragically in the novel "The Flower Raised her Sword." She knows too well that the butler suffered from his one-sided love for the heroine Charlotte and even gave his life to avenge her death. So when Woori wakes up in Charlotte's body, she's determined to steer sweet Lancelot away from his miserable fate. But with the original Charlotte making a reappearance, as well as the villainous Duke Vestia, things might not be so simple after all. Can Woori guide Lancelot to his happy ending without revealing her true identity?
