My Demon Savior (Bill Cipher x reader)

Welcome to Gravity Falls, where nothing is as it seems, especially (Y/n) (L/n). (Y/n) was born a shapeshifter. After Dipper and Mabel find her in the woods, they offer her to come live with her. The night after she gets there, she has a strange dream. It wasn't the fact that it was greyscaled, but the fact that a dashing man around her age had appeared instead of her imaginary cat, Bowl. That's where she finds out the man's name is Bill, Bill Cipher. One day, he appears at the shack, and (Y/n) invites him in, but due to Weirdmageddon, Dipper hates Bill's guts. What will Dipper think when she tells him she's in love with the dream demon?
