He's a ghost and has been a ghost for centuries. He walks around among the people carelessly since he has nothing to care for as a ghost. No one knows about him or his existence. No one can see him, feel him, sense him or his presence. He likes to go to places and mess around for his own entertainment but sometimes he could feel all alone since he has no one to talk to.. One day he decided to mess around in a library a bit before he noticed someone looking at him. The person looked at him?
