A beautiful wife, Rei, who married her beloved husband and lives a happy life. It's not yet that time for her, but she was looking forward to the day when she would have a child, and she made it a daily routine to take her temperature and write it down in her notebook. However, Rei's ovulation day is turned into a cruel day by a strange-looking man who hides his face with her balaclava. Too selfish to impregnate Rei, her married woman, with her own seed? Pu! A man runs atrocities not for pleasure but to leave descendants!
