Isabel was forced by her stepsister Clara to lose her virginity to Sebastian, the heir to the largest hospital in town. Clara wanted to deceive Sebastian into marrying her, but she failed. Enraged and humiliated, Clara repeatedly tormented Isabel. However, she picked the wrong person to mess with—she didn't know that Sebastian had already fallen madly in love with Isabel that night. He decided to claim her, marry her, cherish her, and make anyone who dared lay a finger on her pay the price.
