Dipper and mable

Ok so this is basically like holy crap omg this is one of the deepest things in the gravity falls fandom I takes a lot of digging to find something on it but it's mable and dipper are the dream demons and bill is the kid who visits gravity falls to see grunkle Stan so basically this is a story where you fall in love with billy who has mables and dippers personality and are terrorized by Mable and dipper who have bills personality so..... Yea
