The thing that Shen Qingli regrets the most is probably having a one-night affair with the man she had secretly loved for eight years and then letting him pay her. From then on, Gu Heng became intimately involved with her at night, while treating her like a stranger during the day. When he was about to arrange a marriage, Shen Qingli thought they could part ways amicably. But instead, he took her back to his home. Old grudges and unresolved issues in the Gu family led to a dramatic turn of events. Gu Heng, injured, sent Shen Qingli away but kept reappearing to save her from danger. Shen Qingli thought she was just a toy, dispensable. Little did she know, he had long fallen in love with her and had become addicted to her.
