For Letizia, the term “Princess” is only a useless endearment. She was treated like a rag in the Esquar, and when she reached the adult age, her father set her into an arranged marriage with the rumored violent and ugly man, Knox Renoir. For her, this is the same as sending her to another hell.   Letizia was forced to accept her fate. But she declined to die alone. She thought that once Knox finds out that she’s not v*rgin anymore, he will get mad at her family, and a war will start between Renoir and Esquar. Letizia, who gave up on her life and happiness, was determined to bring down the Esquar which abandoned her.   On the day of her wedding, Letizia met her groom for the first time. Knox was wearing a mask to conceal his face, and unlike the rumor, he was gentle and considerate to Letizia throughout the ceremony. When the ceremony ended and they finished giving their vows, Letizia saw a familiar man from afar. It is Austin, the man she loves, the man who disappeared after promising that he will marry her, and the man whom she waited for years.   It was then, Letizia realized that she should not give up her hope and escape if chance arrived.   But is it possible to happen when Austin turns out to be her husband’s brother?   A mysterious and secretive enemy became her husband.   A former lover became her brother-in-law.   It is a marriage without faithfulness. But true love blooms in the most unexpected way.
