Turn It Up (2001)

A high school classroom… The students have pushed their desks out of the way and are busy dancing. It seems that they are conducting some kind of bet to see who can show off the best moves. Once again, Cheol-min takes over and is declared champion for the day. He returns the money he wins but is obviously high on his victory. He preens in front of So-yeon, the object of his affections. So-yeon, well aware of Cheol-min's feelings, only has eyes..
