A story of the lives of the Gleeful twins in Gravity Falls, Oregon. They are know for their famous magic shows and tricky reputation. As Dipper and Mabel continue in their day to day lives, they grow farther apart, while Dipper and their household servant, Will, grow closer...

Dipper and Mabel Pines return to Gravity Falls at 16 years of age. Mabel is determined to find her soulmate now that she's finally 16, while Dipper would just like a usual summer of Gravity Falls. At first glance, it seems like another few months there, but things very quickly take a wild turn the second a strange man shows up looking for something. This soulmate AU is based on symbols. Each person's mark is related to their zodiac or any symbol that might represent them. For example, Mabel's is on her chest in the shape of a shooting star, Dipper's is a pinetree on his forehead, and Bill's is a triangle under his eye patch. This mark is invisible and only begins to glow when the person is in the presence of their soulmate- the closer they are, the brighter the glow. However, the marks only glow once the person turns sixteen of age.
