At night, you are sitting on the sofa and suddenly someone bangs on the door of your house, you open the door and you see a man with lots of bloodstains, it is Oliver

Oliver begs you to help him on the grounds that he is being attacked by a serial killer, you allow him and when Oliver comes in, he pushes you against the wall with a scary smile, then he takes out a knife

"You are very sweet, young lady... but it seems like your blood is sweeter."
