Dipper comes back to Gravity Falls, but things aren't the same. Mabel has some new friends and Dipper's body is only changing for the worst, in his opinion, not to mention the fact he's now discovered that he's bi.
He ends up in the middle of a giant game of cat and mouse, set up by his sister, with seven guys fighting for his heart. His depression only worsens with these new obstacles and it seems as if he's doomed to a life of tyranny and unhappiness. Then comes Bill Cipher to the rescue.
Bill doesn't know what he wants to do with the rest of eternity anymore, but that is until he finds out who his prophesied soulmate is.
The two, in their own time of need, create an irreplaceable bond that must survive and solve life's toughest of problems. Together they create music and love.
