A Deal's a Deal (Bill Cipher x Reader)

"Listen Sweetheart, My name's Bill, Bill Cipher, now do you want to hear my deal, because it kind of involves your friends, your choice my dear." He said with a smirk on his face.

"Fine. What's your deal?"

Bill Cipher, the triangle dream demon with a thirst for power, has come back to Gravity Falls, seeking revenge. However, something caught his eye, something in particaular. He begins to feel things he has never felt for anyone before when he mets you. Somehow you manage to capture his heart, but he has yet to catch yours. He, along with Mabel, try to make you swoon and fall the beloved Bill Cipher, but in the midst of their plan he conjures up something big, something that could shatter the world into pieces.

I do not own Gravity Falls or its characters.
