A beautiful wife, Misaki, who has been married to her husband for a year. It was almost time for me to want to have a child, and it was my daily routine to measure my body temperature and fill in a notebook. And on the day of ovulation that I was looking forward to ... fear comes. A mysterious man who set up a voyeur camera at the cape's house and knew everything from the day of ovulation to the couple's business visited with a strange figure hiding his true face. I'm trying to fertilize my seeds on a cape that wants to get pregnant.
