Dipper x Reader: You and your older sister have been going all around the world together after your parents died. You've been everywhere in the world. Your next stop; Gravity Falls. Your older sister became good friends with an 19 year old girl named Wendy. One day, your older sister said that she was going to visit Wendy at a place called the Mystery Shack. You decided to tag along. When you get there, you meet two kids. One that's SUPER friendly, and one that doesn't seem to like you as much. Will you be able to become friends with both of them and start to have feelings for one of them? Or will you become friends with only one and not the other?
