Once, a long time ago, people believed that vampires still exist and lived together with them in peace. Everything was in control, but that day, all of a sudden, everything turned upside down. Vampires and humans battled each other, resulting in many deaths from both sides. After the war, it was said that all the vampires that had ever existed was gone. Everyone believed this, except for one girl......................her name is Kim Taeyeon. But why? Because she herself is a vampire, a pureblood, the strongest race of vampire.
