"Dear sister, it has been a year since you passed. Since that...thing took over you. I think you'd be happy to know that I found a safe place to be. A place where I'm alone. Away from any other human. You may think I'm lonely, and sometimes that's true, but do not worry! This is the way I can be safe, the only way to live!"
The world has pretty much ended. Those things...they showed up and just took over. Joanne has found a safe place to be, where she can be all alone. After all, you never know if what you're talking to is a human, or one of them. Luckly the radio still works, and for a while now you have been hearing the pleads for help of a stranger. Will you answer they call? And if you do, will you help them?
