You're a ghost. No one can hear you, see you, or feel you. Recently you've started to haunt a college student around your age, his name is Teru. He's an exorcist.

He'd be your best friend if you could only communicate, you're sure of it - And then one day, he look up and ask you.

"Why do you keep following me? are you trying to irritate me?" He asks, looking like he may be getting angry, though it's hard to tell. He keeps his voice calm, at least.
