Revenge on the Real One

Having been switched with Duke Yutrit's real daughter at birth, Helga does her best to earn her family's love, only to be treated like a placeholder. When the real Helga is found and returns to the family, the "fake" Helga is forced to give up her position as the family successor and live as Hillianne, Helga's "long-lost twin sister." But "Hillianne" plans to get revenge by weaponizing Helga's lack of experience as a noble lady and disgracing the Yutrit name. Real lady or not, she'll be the one laughing in the end!
