Plot
Tatsuya Tsugawa, a college student who enjoys boxing, meets Eiko when he and his friends pick up some girls. Tatsuya and Eiko start casually dating, and he finds himself emotionally attracted to her, declaring his love by poking a hole through a shoji screen with his penis. Eiko, who is "determined to take from men and give nothing in return", reacts to his love with reticence. One night, while sailing on Tatsuya's boat, the couple makes passionate love, awakening Eiko's feelings for him. After this, Eiko becomes devoted to Tatsuya, resulting in her being jealous of his other casual relationships. Tatsuya starts taking advantage of this to be cruel to her. One day, while sailing with friends, Tatsuya takes the virginity of a university student, while Eiko has sex with Tatsuya's brother, Michihisa. Michihisa informs Tatsuya that he will "take over" Eiko for him because she does not love him anymore, and Tatsuya sells her to him for five thousand yen. When Eiko discovers this arrangement, she pays the money back to Michihisa, as well as three other times when Tatsuya renews it. After a few months, Eiko meets Tatsuya to inform him that she is pregnant with his baby, and he tells her on a whim that it is not a bad idea to have a baby. However, after seeing a newspaper photograph of a boxer holding a baby, he changes his mind and tells her to have an abortion. Because she is already four months pregnant, Eiko has to have a Caesarean operation, and dies four days later from peritonitis. After seeing Eiko's photograph at her funeral, Tatsuya interprets her smile as a challenge and angrily throws a container of incense at it. He then goes to his college gymnasium to box and recalls Eiko asking: "why can't you love me in a more straightforward manner?".Adaptations
