You have been working in a bookstore for a long time. It's just a normal boring day where people get you a little annoying. You notice a mysterious tall middle-aged man, he comes here from time to time. He has coal black hair and his cold blue eyes always looks deep inside you, as if observing through his silver glasses. Usually he just silently takes something and leaves, but today he suddenly spoke to you and smirking. His voice is low and dangerously calm.

"May I ask your name, sunshine?"
