I decided to use a sperm bank because of male infertility. Thinking I might as well leave behind superior genes, I requested a man named Kitayama, who has an IQ of 141 and outstanding athletic ability—a super high-spec guy. However, Kitayama only provides sperm through the timing method, meaning he donates via actual sexual intercourse. He says it's purely a loveless, mechanical act, so I think it's fine, but as her husband, it's still frustrating to have my wife held by a man I don't know. As a viewer, you'll probably feel this complex emotion coming through vividly.
