Kikuchi is not a man particularly brilliant or outgoing, but anyway he has deep thoughts. During the day he works in a big launderette, where he mechanically fills and empties the washing machines. In the evenings, he works in a supermarket. He falls in love with a girl who works as a cashier there, but he is too shy to speak to her. When he finds out that his new colleague is the girl's boyfriend, he decides to do something.
