In a stunning mansion, four charming fifteen-year-old boys reside for free under one condition: within three years, they must refine the owner's shy niece into a sophisticated lady. The niece, Sunako Nakahara, is an agoraphobic, horror enthusiast with a face marked by acne, wild hair, and a fashion sense amiss, prone to nosebleeds around handsome individuals. This challenge proves to be a monumental task, requiring nothing short of a miracle from our unsuspecting heroes.
