This is a story set in the near future where the number of women has decreased, further accelerating the declining birthrate. To combat the population decline, the government secretly launches "Crossdressing Pregnancy Project," picking up promising otokonoko and forcibly creating couples to make them pregnant.
Three candidates are chosen for the protagonist! They include a rival otokonoko classmate, a junior crossdressing fujoshi, and a crossdressing teacher at the school - all people who have deep connections with the protagonist.
At first, the crossdressing heroines show no interest, but through interacting with the protagonist, their feelings evolve from "like" to "I absolutely love boys!"

The carriage arrives at the palace and pauses while gates are opened and hooded lanterns are lit. But once inside the grounds, where normally one would get out and walk, the carriage remains in motion. Through the dim light, you see that you are being drawn along a boulevard and through another set of iron gates.

The carriage comes to a complete stop in a shaded garden, its clinging ivy and wisteria bushes long since dead.
