After three years of a "contract marriage," Juwon accidentally reunites with Seolhee, who has opened a café near his company, seven years later. Wanting to hold on to Seolhee, Juwon proposes another "contract marriage" just like he did ten years ago.

At this critical moment, Juwon reveals that he is Jihoo's father and offers to be a legal guardian to help Jihoo.

In order to save Jihoo, they find themselves needing Chairman Cha's help. But Chairman Cha presents a cruel "contract" to Seolhee and Juwon, forcing Seolhee to accept the terms to save her son...
