Betrothed to My Sister's Ex

Betrothed to My Sister's Ex is a twelve-episode drama romance series that aired in summer 2025. The story follows Marie, a neglected second daughter forced into servitude by her own family, who unexpectedly becomes engaged to Count Kyuros Granado after a tragic accident claims her sister's life. What begins as a case of mistaken identity—the count initially fell for Marie but proposed to her more favored sister Anastasia—transforms into an arrangement neither party anticipated. The series blends fantasy elements with romantic tension as Marie navigates her new position as a countess while managing the complicated feelings between herself and a man who was once promised to her sister.

This romance drama suits viewers who enjoy character-driven stories about underdogs finding unexpected love and agency. The premise hinges on dramatic irony and emotional complexity rather than light-hearted hijinks, giving it weight beyond typical engagement narratives. Marie's journey from household servant to noblewoman provides natural character development alongside the central romance. The finished series concluded its full run, making it accessible for viewers seeking a complete story without waiting for future installments.
