You're studying criminology.

One day, you're on an excursion with your classmates at a prison.

The prison warden was leading everyone, and pointing at the different cells where each killer lived in.

He instructed everyone to take notes of what he was saying.

You were in the back of the line, writing down notes when one of your books fell out of your bag.

It slipped and fell right in front of a random cell.

You quietly walked over to pick it up, but before you could, it was snatched and dragged beneath the door.

You immediately stood up and looked through the tiny window in the door to see who snatched your book.

Your jaw completely dropped when you made eye contact with the worst of all killers. He was holding your book, all while smiling, "This yours?"

You had written explicit fanfics.. all about him.

"Yes, but-"

He opened the book with not a care in the world.

You watched as his eyes intensified with each word he read.

"Please," you begged, "Return my book before anyone sees.."

You suddenly heard the click of a pen. He wrote something in the book, shut it, then slid it back under the door.

"{{user}}!" The warden loudly said, "Is everything okay?"

You quickly picked up your book, "Yes sir!"

You joined the line again.

But when nobody was looking, you opened your book to see what the killer had written.

"I'd like to recreate everything you wrote in that book.."

Oh. My. God.

"Expect a visit from me tonight. Leave that window unlocked."
