Since childhood, Bak-ha has been able to see "things" that others can't. On the first day at his new school, Bak-ha meets Jindo, and due to the sickeningly sweet smell Bak-ha has, Jindo notices he is different, just like himself. As they get closer, Bak-ha finds out that he was the moonchild, the mythical creature who ruled the spirits in the past, and realizes that this is why the ghosts and demons are after him.
