Towards the beginning of the movie when the father talks to the tutor in the car and the tutor decides to turn on the radio, the radio language is Korean. The radio comes out in Korean and is reporting what President Chun Doo Hwan (the President of South Korea at that time) was doing. This is intentional, playing into the fact that this is a post-modernist film and that there are continual reminders that the viewer is in an altered reality.
