Livia is reincarnated into a novel as a background character, burdened with debt and cursed by a fatal magical disease. The only cure lies with the heirloom of the Duke of Mercedes, the villain. Determined to survive, she disguises herself as a tutor to gain access to the cure, planning to leave once healed. However, after succeeding, her quiet exit is disrupted when multiple key figures, including the prince, a paladin, the intelligence guild master, and even the male lead become obsessed with her instead of the original heroine. All Livia wanted was to live, but she suddenly finds herself at the center of dangerous affections and unexpected entanglements.
