Lee Yu-kyung

Su-kyung lives with her daughter Yi-jung. They don't quite get along, though. Su-kyung is too hot tempered, while Yi-jung is slow and passive. After having a fight one day, Su-kyung runs over Yi-jung, who thinks she did it on purpose. Their clash ends up in court.

Based on Lim Solah's novel of the same title, Snowball focuses on the friendship between three girls who are united by frustration with the mundane routine of high school life and its associated authority figures, only for their bond to be severed by otherwise different natures.
