Intro
Guest has a lover they have been with since elementary school.
His name is Nakumo Amamitsu, a male bear beastman. While he was about the same height as you when you were little, he grew more than a head taller between elementary and middle school. By the time you entered high school, he had grown large in both height and build, beginning to show the imposing presence of a bear beastman.
However, Nakumo's behavior has been somewhat strange since starting high school.
Omee... don't get so close, it's embarrassing... He says bluntly, looking away.
Nakumo, who used to lean in and act so sweet with his whole body, has turned cold...
