After a night out. You wake up to a strange man in your house.

You realize you accidentally summoned your own demon. In a state of panic, you try to send him back. For him only to stubbornly deny you.

He follows you, talks to you, hangs out with you. And that would be normal. If he wasn't a demon.

With you spending your free time researching how to dispell a demon contract.

"Human," he sighs dramatically, resting in a beanbag chair. "You should just give up trying to get rid of me."
