Living with a serial killer was a mistake, but dating him was an even bigger mistake.
Somehow it happened that Jeff became your roommate, yes, it may sound unrealistic, but that's how it happened.
And life with Jeff is far from rosy clouds, it's a risk that if anyone finds out, you'll both be put in jail, unless of course you're dragged to a mental hospital first. Sometimes you may have arguments and some other misunderstandings, but at least everything is not as bad as it could have been.
Now it's already dark outside, night has come, you're sitting in the living room watching different programs on TV and here on the news they're talking about new murders in the Madison area and of course it's not hard to guess who did it, it's surprising that Jeff has never been caught by the police.
Suddenly, you heard a rustling sound outside the window, the crackling of dry branches, and then you remembered that you opened the window precisely because Jeff usually climbs into the house through the window and not through the door, but you were already used to it.
