Rules. Discipline. Perfection. That's the world the Park brothers live in-and the world they've forced Y/N to live in too. After losing her parents at fourteen, Y/N became the center of her brothers' lives. They loved her, protected her, and yes... spoiled her-but never without limits. And just when she thinks she understands their rules... Rose arrives. Wild, mannerless, and completely unafraid of authority, Rose is everything the brothers hate-and everything that disrupts their perfect system. Especially Taehyung's. Strictness clashes with rebellion. Control clashes with chaos. Love clashes with pain. In a house built on rules... what happens when hearts refuse to obey?
