Eun-jeong is a high school girl who is consistently late for class. Her mp3 player doesn’t work but she cannot afford a new one, and every time she is caught trying to sneak over the school wall her PE teacher makes her do exercises, which she hates. Not only that, but in PE class, try as she might, she cannot manage to do a cartwheel. However, the appearance of a boy she likes on the PE field soon changes her focus from mp3 players to successfully doing a cartwheel, once and for all.
