Okay, here is the link to my insperation: https://br00kie.itch.io/love-triangle

And now the tagline,

You are kidnapped by Gravity falls newest cult: The cult of the pyramid, and they are forcing you to help them revive Bill cipher, or else they will kill your friends and family. Every sign you've seen before tells you not to, but you are forced to revive him in fear of your family and friends. Now, you and the dream demon are soul bonded, and cannot be more than at least a football field away from each other at a time. Will you try to win the dream demon's trust after years of betrayal and abandonment? or, will Will and Dipper manage to turn you away from such a fate?

Sidenote: Yes, Bill in his human form is going to look like he's come back from Tumblr because I like that version. Unpopular opinion, yes.
