In a romance-fantasy world overflowing with regressors, reincarnators, and transmigrators, May is none of these—she’s just a completely ordinary “native” extra with no past-life memories, no missions, and no special cheat powers. The only strange ability she has is this: she can see the “titles” of the books the romance-fantasy heroines have transmigrated from—and those titles are actually ultra-long, ultra-spoiler summaries of the entire plot. May hides this bizarre power and lives quietly… until a romance-fantasy heroine named Seol Eun-chae possesses the body of her beloved younger sister. Desperate to get her sister back, she searches for a way and hears an unbelievable answer from a certain “Master”: “The only way to drive out a transmigrator is one—seduce that transmigrator’s male lead first.” But wait. Seol Eun-chae’s male lead is… the tyrant Lihaim Elivton, a man with a 0.000001% “success rate” whom countless other heroines have tried and failed to charm, getting kicked out of their possessed bodies in the process. With no regression, no transmigration, and no reincarnation—just as an extra—can May really seduce Lihaim? For the sake of her precious sister, May resolves to shake the tyrant’s heart using the only weapon she has: the meta-knowledge hidden in those “titles” only she can see.
