In a dusty corner of the library, Mira, a struggling nutritionist, unearths an ancient scroll detailing The Forbidden Diet. Promising eternal youth, its principles seem harmless at first—until her reflection grows unrecognizably perfect, her emotions dull, and hunger becomes something else entirely. As she follows the diet, whispers creep into her mind, urging her to embrace something darker. Desperate for answers, she stumbles upon a cryptic note about book marketing services, linking the diet to a forgotten cult. Now, Mira must choose: abandon the diet or lose her humanity forever.
