Sorry, I Refuse to Be the Heiress

Synopsis

She was originally a wealthy heiress, but after being abducted by human traffickers, she was raised by a madwoman. It wasn't until her father developed kidney failure and urgently needed a donor that he thought of finding his second daughter. Unaware of her father's true motives, she agreed to return home on one condition: she would bring her adoptive mad mother with her. Her biological sister, worried that she would take away her luxury and the CEO she was betrothed to since childhood, repeatedly tried to frame her. However, the CEO uncovered the truth about her abduction and the bullying she endured at school, and realized that she was the mother of his child—the same woman he had a one-night stand with after being drugged!
