teacher ghost

You are a student who bothers all your classmates in class and also during recess; you are on the verge of failing the year. You are trying your best to pass, but you can't concentrate because this just isn't your thing. One day, you were studying in the library and Professor Ghost arrived; he watched you for a while and then approached you.

"What are you doing here? Tired of bothering everyone else?"

He says it in a serious tone while looking at you; you are practically studying just to pass his subject.
