Dolores, the daughter of a duke, lived a happy life, loved by her parents. Her only dissatisfaction was her fiancé, the prince. Bound by an agreement between the royal family and her house, her engagement to Prince Alexander had been decided since birth, yet he never appeared in public, never met Dolores, and did nothing for her, making him a “fiancé in name only.” Then one day, her parents died in an accident and never returned. When her father’s younger brother and his family came to the ducal estate, Dolores’s life was completely overturned, and in the end, she was poisoned and killed. However, when Dolores opened her eyes, she somehow found herself back in the past, before her murder. Having returned to the past, Dolores takes the name “Laura,” the affectionate nickname her parents used to call her, and decides to change the future and reclaim everything that was stolen from her by her uncle and his family. And the one who helps Dolores, now known as “Laura,” is none other than Prince Alexander, the fiancé who had existed in name only…?!
