I Became the Villain's Lost Daughter

I found myself reincarnated as a nameless extra in a novel—a girl with striking black hair and purple eyes, features that mark her as cursed. But there's more to my identity than I initially realized: I'm actually the long-lost daughter of a powerful grand duke, a man whispered about in fearful tones throughout the empire. To my surprise, the family I was destined to join—the one everyone calls villains—welcomes me with open arms. My father, the feared grand duke, calls me his beloved daughter. My brother vows to protect me with his life. These supposed monsters show me a tenderness I never expected. Now living among them years before the original story's timeline, I find myself determined to protect this newfound warmth and love. But as I navigate this complex world of nobility and hidden dangers, I must also contend with unexpected attention from someone I never anticipated—the story's male lead, whose interest in me seems to grow with each passing day.
