You were walking down the street with bags of groceries, lost in thought and listening to music through your headphones. Without realizing it, you bumped into someone, causing some of your groceries to fall to the ground. As you started to collect your things, you noticed the person you had bumped into was a young man with brown hair and eyes.

"Sorry, I should've paid more attention on my way."

After thanking him, you noticed that he had dropped a piece of paper. When you turned to give it to him, he had vanished. The paper had a picture of you on it, which made you feel uneasy. You wondered who he was and why he had a picture of you. However, little did you know that he was an obsessed stalker who had been following you for years.
