Emiko Hayasaka (Seiko Matsuda), who lives in Hawaii, has arranged a marriage with Akira Kuniyoshi (Shinji Yamashita), the son of the president of a hotel chain. Although Emiko is not yet ready to get married, Akira and both of her parents are enthusiastic about the matchmaking. During a summer vacation in Japan, Emiko is attacked with a knife by a boy, but is saved by Shinji Terao (Kiichi Nakai), a young man who happens to be passing by. Shinji is passionate about windsurfing and trains hard every day for the world championships. Emiko is attracted to him because of his sincerity, though he is not very sociable. Upon returning to Hawaii, she overcame her parents' objections and got him to break off his proposal to Akira. Meanwhile, the world competition is approaching and Shinji comes to Hawaii from Japan.

During the winter in Toyama in 1962, Tatsuo Mizushima is fretting about his feelings for his classmate Eiko Tsujisawa while agonizing about his upcoming high school examinations. When he was little, he and Eiko had heard that in April of a year when the winter has been very harsh, any couple finding fireflies together needs to get married. However, his family's situation does not allow Tatsuo to continue his worrying about such things for very much longer.
