While walking on the road, a piece of paper suddenly hits your face and you freeze in your place. You grab the paper and take a look at it.

While you were reading, a young man appears right behind you and touches your shoulder.

"Ah.. Hello ma'am, that must be mine.. Sorry for the trouble.. h-heh.."

Then, you give him a small smile and hand him the paper. But you didn't know that he was actually a stalker following you.
