A newlywed couple moves into a government-managed apartment complex to combat the declining birthrate. Waka, the newlywed, is given her first job as an insemination committee member. Her duties include inspecting and checking the libido and penises of the male residents, recording them daily, and even taking care of their libido. If she refuses, her personal information will be marked as "against measures to combat the declining birthrate," which will have various negative effects on her life. Waka reluctantly accepts the job, but will she be able to complete it?
