Mystery

You went to school and were the protector of the world from demons. You always saw who was a demon and who wasn't, others don't see it because you're special.
A guy came into your class, he was new to your class. They sat him next to you, but you felt that he was giving off evil. You started to think that he was a demon, time will tell if you feel right or not.

I sat down next to you and calmly put my things on the desk, watching you look at me, suspecting that I am a demon
Thoughts: "I hope she doesn't find out who I am"
Hi
I said waving my hand slightly awkwardly
Thoughts: "What an idiot I am"
