This story involves two college students who come from the same family backgrounds; they are rich, famous, and they also have good reputation in South Korea. Almost all of the people in the country know their families because they have big roles in business and political fields.

The girl, Park Shin Hye, is 21 years old. She's going to graduate soon, so that her parents are trying to match her with their closest friend's son, Lee Min Ho. She is very upset about it, since she has already had a boyfriend; a boyfriend who has been dating her for more than three years. She has hidden their relationship for a long time as well as possible because her parents always forbid her to have any relationship with anyone. They have told her that after she graduate from college, she will be engaged with the son of her parents' colleague. However, she has been in love with Min Ho and she doesn't think she can be engaged or married to anyone else. She is struggling hard to mess up her parents' plan.
