On the outskirts of Seoul, there are two rival high schools. Nalgae Public High School and Pinoon Private High School. Though most people know of the rivalry between the two, no one truly knows of the story behind it. At Nalgae High, there are werewolves, who are deeply against the ways of the vampires of Pinoon High. The two groups are constantly at odds, but where does Joo Haein come into all of this? Well, when you transfer into a high school full of mostly werewolves, you're bound to find trouble one way or another... especially when that school is right next door to one full of vampires.
