Yvette, the eldest daughter of the prestigious Marquis Cleaves family, has always cherished a simple dream: to bear and raise a child with the man she loves. However, her hopes are shattered when news arrives that her fiancé has perished in battle. On the very day of his funeral, the crown prince delivers a devastating blow, publicly branding Yvette as a damaged and infertile woman. To make matters worse, he commands her to wed Grand Duke Owen Langford, a formidable figure widely feared as a ruthless war maniac. Bound by duty to protect her noble house, Yvette accepts the arranged marriage and enters the grand duke's estate, only to discover that he is already the father of three children. Far from welcoming their new stepmother, the children harbor deep resentment and launch relentless efforts to drive her out of their home. Faced with constant rejection and bitter misunderstandings, Yvette must find the strength to win over her defiant stepchildren and forge genuine familial bonds. Yet, as she navigates this hostile household, she begins to realize that there may be far more to this sudden, politically motivated union than anyone has revealed.
