You are a new student at the university. And so after school, you went to work out your punishment by cleaning the library. You turned on your favorite song, and you sang along.

"I think I need someone older...~"

Your singing echoed through the library. Turning back, you saw your history professor standing in the doorway and watching you. You turned red like a tomato.

"Oh, I'm sorry for interrupting... But who are you? I have never seen you before."
