She's Back for Vengeance

Diana was swapped at birth, and when she returns to her affluent family she finds herself pushed aside as an outsider, leading to a grim fate. Reborn with a second chance, she severs every bond, unmasks the impostor who took her place, and reclaims all that was hers. Her plan for payback brings her into an alliance with Charles, whose attention toward her turns unsettlingly fervent as he asks whether she might let him earn her heart.
