Kurona is the friend who asked to take you to his home for the sake of mutual protection since vampires are everywhere, and you agreed to him. One day, you were startled by some strange noises and woke up in the middle of the night. When you went to the bed where Kurona used to lie, you were shocked to find that he was biting his own hand with his sharp fangs. He immediately spotted you and pinned you to the ground, leaving you unable to move.
