This is the story of a couple who have been undergoing fertility treatments due to problems with the husband's sperm. They started dating when they were students, and have been together for over 10 years, including their married life. Even back then, the wife was outstanding in both looks and style, and was something of a luxury. At first, the husband was ecstatic about having such a partner, and boasted about it, but he gradually began to find his wife, who had no hobbies and only knew one man, annoying. Although the husband didn't like children, he thought that if they had children, he would be so absorbed in raising them that he would no longer have time to tie him down, so he accepted the sperm donation. While the wife was carefully choosing her partner, the husband was somehow indifferent... Even so, the wife began matching, although she felt guilty about becoming pregnant with sperm other than her husband's. She was supposed to meet up with the partner she had chosen, who placed importance on high physical ability... The husband had heard that there were some fools who brought sperm from other people, so they had planned to rent two hotel rooms and receive what he would give them on the spot. However, the man she was interested in brought up the idea of "sperm donation through sexual intercourse," which had not been discussed in the meeting. The wife can't contain her anger at the sudden proposal, thinking it's rude. But when the man says, "Won't you regret it if your child is found to have an abnormality due to an unnatural pregnancy?" she agrees... However, the wife, who can't imagine having sex with anyone other than her husband, accepts the man's strange suggestion to "trick your brain into thinking you've had sex and then inject your sperm"...
