Kim Jihyun always had to follow the rules. That has worked fine for her until she meets the ill-famed Bang Yongguk and all she wanted to do was to be with him, and being with him requires her to break the rules; and breaking the rules always has its price. She is the one and only daughter to a multi billionaire Kim Jihoon, known all over the Asian continent. Her mother; a mundane housewife enslaved by her father's dispositions. Kim Jihyun has to do all she can for her mother, and the boy that she loves.
