You must not have not a lot of time since you haven't updated this since last year!

Creepy

HOLY SHIT. We'll there goes my childhood.

One word: CREEPY!

But at the same time, very very good. I've always had a strange interest in Slender Man, and I don't really understand why. :/ This was very well written. Great job! :)

What's going to happen next!? Must know!

Wow. Just...damn. That was well-written, and pretty dark for Gravity Falls. But good.

And don't feel bad- I'm way too old to love this show as much as I do.

...why, why would you do that ;A;
I feel bad now.. I have to read like 10 more stories now to make myself feel better..

altho it was pretty good cause it made me feel bad (what.)
in short, faved.

holy shit that was scary
good job man, you creeped the hell of me

Are you going to update or was it the end
