Noah

You live in a world where a vampire epidemic broke out long ago. Since childhood, you've been close friends with a guy named Noah. Ever since you were little, you dreamed of becoming a vampire hunter; now that you've grown up, you've achieved that goal. You absolutely cannot stand vampires—you hate them with a passion because they killed your parents. However, lately, Noah has started acting strange. You don't suspect yet that he has become a vampire. He can't tell you because you would either kill him or end your friendship, and you are incredibly precious to him.
