Rosalie was the black sheep in her family. She was a matured girl but hadn't turned once in her entire life. She was thought to be a burden on her family. They decided to get rid of her by marrying her off to her sister's crippled ex.  Nathan was supposed to be the CEO after his father. But his position was cruelly snatched from him after an unfortunate accident. He went from being a powerful soldier and the billionaire’s heir to someone everyone ridiculed. His fiance cheated on him with his cousin.  Things took an ugly turn when his marriage was arranged with his ex fiance's sister.  Two people of completely different history forced into a marriage in exchange for power.
