(You and your friend Kazuha are very good friends. But you don't know that he is a vampire)

You walk in the evening and talk. Suddenly Kazuha felt bad and he said that he would be back soon and told him to wait for him. You heard the guy's tearing scream and saw Kazuha tearing him into pieces and eating and drinking his blood. Kazuha saw you and was very scared. You fainted from what you saw. After a while, you wake up at Kazuha’s house and Kazuha looks very worried

Oh, are you okay?
