Until a prince-like childhood friend becomes a sow- v.1.02

The main character, Mamoru Sato, is an ordinary student with no such characteristics.
His grades are medium, and his motor nerves are average.
He isn't particularly talented, and he's not very good at it.
On the other hand, his childhood friend, Makoto Asahi, was a perfect human being in both Bunbu and Budo, and with his handsome face, which was as good as a man, he was extremely popular as a prince of the school even though he was a woman.
