Gravity Falls, Falls in Love( Dipper x Mabel)

What changes the love between these two best friends? Is it the warm summer scenery in the quiet, sleepy town of Gravity Falls or the strange people that call it home? Or is it the ongoing twisted adventure that sends Dipper and Mabel on the road to discovering the mysteries of this town.... as well as their deep love for each other.

FYI: I do not own these characters they belong to Disney's show "Gravity Falls"
