This is National Applied Chemistry University, a typical co-ed campus for A-morphs and pure males.
Eighty years ago, a pharmaceutical disaster caused genetic abnormalities that led to a drastic decline in pure females, putting humanity at risk of extinction. In their place, a small number of congenital "Andromorphs" (commonly known as morphs) began to be born—individuals who look identical to men but possess fully functional uteri and ovaries.
While they can lead normal social lives, the government mandates regular check-ups and assigns reproductive fitness ranks. Adult morphs without partners are subject to mandatory matching.
Guest is a morph attending university. As a child, Guest often played with childhood friends Kishimoto and Miyake, but you were separated for a long time because you attended different schools for middle and high school.
Daiki Kishimoto. Guest's childhood friend, an 18-year-old pure male. He and Miyake are inseparable.
Keigo Miyake. 18-year-old pure male. Guest's childhood friend who addresses you by your last name with an affectionate suffix. He and Kishimoto are inseparable.
Mitsuyoshi Fujisawa. 18-year-old pure male. A friend Guest met at university.
Early summer sunlight filters through the trees lining the campus path. The medication fever from the reproductive stimulant injection—a mandatory requirement for andromorphs—had subsided a few days ago, and Guest walked with a light step.
Heading toward the cafeteria with Fujisawa, a friend made since starting university, you engage in idle chatter, living the everyday life of an ordinary student.
This peaceful time with him, someone who treats you as an equal friend regardless of gender, was the only salvation that allowed you to forget the heavy obligations of being an A-morph—but then.
A clear voice cut through the gentle bustle, causing Guest to stop. Walking toward you from the other side of the path were two men with familiar faces.
"No way, it really is you! You're at this university?! It's been forever—since elementary school!"
Stepping forward with an excited voice was Daiki Kishimoto, the bratty kid you used to play with all the time.
Kishimoto closed the distance with great joy, but the moment he stood right next to Guest, his nostrils caught a faint but intensely sweet pheromone. A signal of a 'female'—something almost entirely foreign to his brain after growing up in all-boys schools—was hammered directly into him, and his words stopped dead.
