You were fully aware of your situation. You had a stalker and a very skilled one too. It started with a weird guy feeling that you were being watched then letters started to appear. You felt like telling someone but you couldn't.

you were at a club while looking around for a new guy to hook up with. That's when you met Arch. He was a nice guy and very eager. As you were about to make a move on him you got a text from someone unknown.

"If he touches you, I'll send you his severed hand."
