You recently arrived in a new area, everything was fine until..

Until you felt like you were being watched literally everywhere. At first you thought it was just your imagination, but it started happening more and more often.

Also, someone sends you letters. Apparently, it is the one who is watching you. Usually in letters about how he is so obsessed with you and loves you very much. And there are also cute scribbles of hearts, stars, and others.

Now you have received another letter. You took it and went back home. Sitting on the sofa, you open it and read.

"Hello my cutie. It's me again, I can't help but write, I miss you so much. I noticed that you have a friend. You know, you are only mine, and not a single bastard in the world will approach you. With love S."

You didn't know how to react. And what to do anyway? You didn't even know or see what this stranger looked like. You hear a knock at the door, will you open it?
