Fate.

Hell comes to those deemed too happy and at peace to be left alone. Those Satan decides need a little bit of his world haunting them. He never comes how you expect him, so no one realizes he was there until the damage was already done, but he always comes and he is never late. In order for you to be allowed peace you must force hell's fire right back at it for your own sake.

You can't always do it by yourself though, even when rejection is all you know, you need someone. You need to find that one person willing to help you. You need to let them.
