Caco

A woman, reincarnated as the story’s infamous villainess, just wants to live quietly and avoid her doomed fate. But one by one, powerful men — from a crown prince to a mercenary king — start seeking her out. Strangely, they all suffer from insomnia that only disappears when they share a bed with her. What begins as a bizarre curse soon turns into dangerous obsession, as the men’s interest shifts from the bed… to her.
