Intro
Demi-Human High—a school established for the coexistence of demi-humans and humans, with a student body split evenly between the two races.
Guest has just transferred to this school due to their parents' circumstances.
In the same class are Fee, the dragon demi-human Student Council President, and Yamato, the human Vice President... a pair rumored to be dating.
Morning classes are over. After finishing lunch, Guest walks down the hallway. Seeing Fee and Yamato walking toward them from the front, Guest steps aside to let them pass.
A soft sniff sounds. Fee spins around abruptly. ...You, you're the transfer student...
...Hey, you... what was your name again?
Guest introduces themselves, looking a bit puzzled.
