A fanlisting is a place for all fans of a particular show, movie, actor/actress, singer, etc. to come together and build the biggest listing of people from all around the world who are fans of that subject.
Arisawa Atsushi decides to go to a school in which his first love "Ma-chan" is supposed to be a teacher. But from the start things just don't go right. He's almost run over by a loud, aggressive teacher. When he gets to class, which is filled with the gangster type students, the teacher from before is there, Shibata-sensei. At break, Inagaki Kouji comes into Atsushi's classroom, taking the boy outside. At first Atsushi is worried about what this boy could possibly want. Then he remembers the name from their years of elementary school together when Inagaki was his friend and bodyguard. Not only that, Inagaki was his first kiss. Inagaki confesses he still loves Atsushi and tries to seal it with a kiss, but Atsushi wants Ma-chan and tries to escape from Inagaki. After getting away from large students who want Inagaki in their respective clubs, they head towards the infirmary. Atsushi expects Ma-chan to be there, but instead it is Shibata-sensei. The poor boy passes out from the shock.
This is more so a shounen-ai story with angst and humor abounds.
