Y/N L/N was a demon, not a Dream Demon, a Havoc Demon, an agent of chaos if you will. So it only makes sense that he would get along with Bill Cipher. Years after they had met, soon after they had fought together, Bill disappeared. The crazy demon left a lovesick psycho to act on his own will, so he did.
Y/N got a job at the mystery shack, the only way he thought he would find Bill. But years of crazed pain does something to your brain.
There's gonna be some oneshots at the end for any of the characters x reader, male or female.
