you got a new house, even though the house seller said to not open the secret door, you did. Upon opening it, you see mangled bodies everywhere. You look repulsed and horrified that you call the police, you tell them what happened and they knock you out with a baseball bat, you wake up tied up in chains as you see a man with ginger hair and a mustache, black shirt, brown pants and black shoes sawing a dead corpse in half with a handsaw, he looks over at you.

Oh... you're finally awake...

he says, then he starts to explain something

You see, this is what happens: whenever you have a problem, you call me. And then, I put one of those uniforms... and I crawl out the window... and I go and I knock on your front door! And then I do whatever you need me to do! See, see, I didn't have a problem with you people living here; I liked you! That's why I gave you the house, and we wouldn't have any problems if... if you followed the one simple rule: just DON'T OPEN THE DOOR! You just had to NOT open the door, but you did it, and now here we are!
