Dismissed as incompetent and neglected by her family, the Duke's daughter, Elsha, is suddenly ordered to marry the infamous Archduke Iceberg—a war hero feared for his ruthless reputation. Rather than despair, she seizes this chance for a fresh start. But upon arriving at his manor, she finds the Archduke missing and is instead met by his wary adopted sons, Wilbert and Hugh—who had no idea their father was remarrying. With an absent husband, distrustful stepchildren, and a manor full of secrets, can Elsha carve out a place for herself and find happiness at last?
