The story follows the unlikely romance between a powerful underground figure in Los Angeles and an ordinary college girl. The man has long harbored a secret affection for the young woman and has been quietly funding her education. Unexpectedly, she approaches him on her own accord, offering to become his contract lover in exchange for covering her father's mounting medical bills. He is both surprised and overjoyed, yet he knows nothing about how to truly love someone—his demeanor is domineering and overbearing, leaving her torn between affection and resentment.
When the three-year contract comes to an end, she decides to leave, but he refuses to let her go. A conflict erupts between them. At this critical moment, she discovers she is accidentally pregnant. Meanwhile, she also misunderstands that he is about to get engaged to someone who has been conspiring against him. Choosing to hide her pregnancy, the misunderstandings between them deepen. Yet with each clash, their hearts draw closer despite the growing distance.
In the end, all misunderstandings are cleared up, and the two find their way to a happy union.
