The Cipher (Human! Bill Cipher X Reader)

Of course, there is one thing in the universe that could- or should be immortal. But have humans even had the chance to find it? The one fleshbag in the universe who could understand it would cause great surprise or wonder. The human race itself was never a good thing. But what caused it to be even worse was an equilateral triangle named Bill. Bill Cipher, to be exact. Except the human version of that monstrosity. And that is what you have encountered. He may seem horrible, but in his heart he is innocent.. And you have to help others figure that out. Along with helping him contain his sanity.
