Waka Misono, a newlywed, moves into a government-run "anti-declining birthrate apartment complex." Her first assignment is as a "Breeding Health Committee" member—a strict role requiring her to examine and document male residents' sexual desire and penis conditions, and even provide sexual relief. Refusal would result in her personal record being marked as "opposed to anti-declining birthrate measures," severely impacting her future. Reluctantly accepting the job, can Waka truly endure everything this duty demands?
