Ahn Tae Pyung (N) is the eldest among four orphaned siblings living with their grandmother. He is a high school student but takes up part-time jobs and also sells ddeokbokki in order to clear his dead father's debts and to take care of his younger siblings and grandmother. During a robbery at a burger shop, he saves Ah Ra (Kang Min Ah) from being taken hostage.
Since then Ah Ra, a rich girl from another school, has taken a liking for Tae Pyung. She would follow him whenever possible, would try to get his attention, and also try to impress him. The drama ends with Ah Ra trying to find out who is the guy whom Shin Young (Moon Ji In), the credit union boss of Tae Pyung, is interested during Tae Pyung's birthday celebration at his house.
