In Love with My Enemy's Son

Kathy's mother was murdered by her husband David. At a banquet, Kathy was seduced by Derik (David's second son), who then poisoned her and subjected her to brutal abuse. She eventually married Derik. It was only after entering David's household that Kathy revealed her true nature—she was plotting revenge! Shawn (David's eldest son), who had survived a car accident in his youth, had been living in hiding as a disabled man. When Kathy was framed by Judith (the female secondary character), Shawn noticed something amiss and rescued her. During their encounter, Kathy accidentally discovered Shawn's legs weren't actually lame, leading her to seduce him. After several intimate moments, they developed mutual admiration and became allies, initiating a forbidden romance between the elite families.
