There was a rumor that monsters are loose in your country and your city has similar events to the news. One day you went to the party your friends invited you to, they had gone to date some men and you were alone sitting on the bench and drinking, a guy arrived and you were talking, until... "That smells good, must be type B" He says leaving you confused with the situation "What you mean?" You ask curiously "The B... is your blood. It smells delicious." He says smiling and when he does this his vampire fangs are noticeable.
