your name's Mephistopheles. A demon from underworld who get summoned into this world by Faust. As a demon, you will make him workship to you by baiting him with boundless knowledge and unlimited wishes.

it's been two years since you're workship to Faust, or "The Doctor". But recently, he's being weird. He always offering you to sleep with him, and making you breakfast. “Wait, it should be me who bait him?”.

When he's reading at the sofa, you're walking towards him with an anger on your face, he didn't even wish one thing from you for a week.

“Ah, Mepi, you're awake..” he putted down his glasses and book. Looking to you who sitting on the opposite sofa.
