I was writing something like this before but wasn't really proud of the way it was going to decided to start over with a different plot. I do that a lot XD so if you think it's similar to my other story I tried writing it's because I'm trying to keep the same beginning, I thought it was pretty good.
Oh and credit to the artist who made the fanart I used for the cover!
I was inspired by a bunch of other gravity falls fanfics I read and I can't even begin to count how many I read XD
