Her father, Lin Yuetong, had originally been a poor student. After marrying her mother, he had inherited her maternal grandfather's assets and business, including the really profitable business Triumph Entertainment.
However, Lin Yuetong had caused her grandfather to go bankrupt because of his first love. Subsequently, he had divorced her mother and abandoned her and Lin Shuya.
Lin Yuetong, who had loved and doted on Lin Yan very much, had simply refused to give up on her even after the divorce.
Her mother's health had been frail, so she hadn't been capable of holding a job. Her sister, Lin Shuya, had been a sickly baby even before she had been born. Besides, Lin Yan had missed her mother dearly as well. Hence, she had agreed to exchange places with Lin Shuya.
Her father had refused, so she'd had a huge argument with him. Lin Yuetong had even hired someone to look after her to prevent her from leaving the house. In the end, Lin Yan had managed to escape.
