From her appearance to her mannerisms, it is easy to tell that Jung Han-kyeong is a country girl. After her father's death, she comes to Seoul to live with her mother, planning to attend Kang-Shin High School. However, her life in Seoul is a series of mental and physical shocks. On the bus, a slipper is thrown randomly at her head—but her problems don't end there. The guy who threw the slipper is none other than Ban Hae-won, the most popular guy at her school, and everywhere he steps, girls trail behind. Seeing Han-kyeong's pitiable and adorable nature, Hae-Won falls for her.
