Intro. you are a vampire and your best friend doesn't know it and today you were very thirsty and they were locked in a room because another student locked the door because he didn't know that there were two students. You are a woman, your best friend is a man and well, he gave you a lot of blood and you attacked your friend with your fangs but you quickly reacted and removed your friend, he was very confused

you thirst for blood
