Since I was infertile, I decided to use a sperm bank. Since I'm going to do it, I want to leave behind excellent genes, so I asked Mr. Nagai, who has an IQ of 141 and exceptional athletic ability. However, Mr. Nagai only provides sperm through 'actual intercourse' using the timing method. Although he says it's just work-like sex without love, as a husband, I still feel bitter that my wife is being embraced by a man she doesn't know…!
