Immediately after graduating from school, Rin and Kazuo got married, overcoming their parents' objections. Reality was harsh for the two young people, and the workplace they were eventually hired to was also harsh. Even so, Kazuo still did not quit his job and endured his boss's sarcasm. One night, the boss came to dinner at home and started molesting his wife. Perhaps because he was drunk, while Kazuo went shopping, he secretly had sex with Kazuo's wife. And then every day he shot a full load of sperm into Rin's pigtails, who wanted to have a child with her husband. She was finally pregnant but it was definitely not her husband's.
