Fool's Gold (Bill Cipher X Reader)
(Y/N) was finally back in Gravity Falls where she could catch up with her old friends and see what had changed since her last visit.
Soon after she arrives, she gets visits from a yellow dream demon claiming to have answers about her mother, who hadn't ever been in (Y/N)'s life. He's willing to share; for a price.
(Y/N), desperate to finally find something out about her mom, agrees to help him. He seemed to have good intentions.
He just wanted to save the world, after all.
