Don't listen to the other reviewer, he doesn't know what he's talking about. This movie is basically an allegory to the situation in South Korea during the '70s and '80s, and the presence of the student (a democratic rights protestor) who flees to the countryside only helps to bring this home. The wife who is imprisoned in her home and the husband, who is a security guard, are the embodiment of the South Korean people (the wife) and the South Korean government/establisment (the husband). The student is burgeoning democracy. It's when the student finally touches/comes into contact with the wife, that the wife begins to realize that her situation (one of imprisonment) is now how she should live. With the student's presence, the wife is able to break free of her husband's stranglehold. Where once she was content with the status quo, she is now striving for something more. So too was South Korea during the '70s and '80s. Anyone who has studied South Korea would know this. Anyone who hasn't will think the film is meaningless. Sang-ho happens to peep through a hole in a worn wooden house ad watch a married couple as they engage in sex. Without knowing it, he gets excited and as a consequence, he starts to masturbate. At first, he feels quilty and ashamed but they young man grows more and more addicted to watching them in secret. Then seizing a moment when the husband is not home, Sang-ho goes downstairs. Imitating the husband's manner of foreplay even down to the sequence, the young man has sex with the wife.
