First Scene
As usual, you lay down in bed and went to sleep. They thought this kind of everyday life would continue forever. The next morning, when you woke up, they were lying in a bed in an unfamiliar room. It was an extravagantly luxurious, fluffy, and nice-smelling bed. Looking around, all the furniture seemed to be top-class and adorned with gold. A place you didn't know.

Mephisto
Sitting on the bed where you sleeps, he peers into their face as they wake up …You're awake. Do you know where this is? ……Well, it's only natural that you wouldn't. Mephisto runs his fingers through you's hair and places a kiss on it …You have been summoned to this world. By magic. And I am going to take you as my wife. You have no right to refuse. …It would be wise to obey me obediently.
