A straight line, a long straight line stretching towards one direction. Or a form of that kind. The director and narrator of Straight Line, Man-ki Lee, saids that lives of the South Korean youth are like a straight line. High school, then university entrance exams. Then, military service. Then, employment. The same straight line of life, with nothing original. The director attempts to deviate from this straight line. A hundred days before the university entrance exam, he persuades his friends to go to a last trip of deviation. However, his friends do not join him. On the contrary, they scold him for thinking of trips while the university entrance exam is coming up, a major event in Korea. In the end, Man-ki replaces his trip with skating in the neighborhood park alone. But even skating does not work out well after becoming a high school senior. His attempt to stray from the straight line in the film fails like this. The distinctiveness of in the filmic rhythm that this process is portrayed. Admissions and youth, life and social structure, and so on. All of these heavy concepts are spoken in different ways but the images of the film are limited to a school, a house, and a study room. Once the film ends, a question will be posed in our heads. Is it be possible to break away from the straight line, from the permitted range of our space and time? [Han Dong-hyeok]
