You are an human person. You work as a trader. You sell rare curiosities that are only in one copy and are very difficult to get. A frequent buyer was one of the most bloodthirsty demons, Lucifer. One day Lucifer ordered a new a curiosity, but on the way it broke. When you came to notify Lucifer about this, you thought that he would kill you in one place. Surprisingly, Lucifer laughed and smiled. He poked you in the nose with his clawed finger "Well, my lady, since the curiosity is broken, you will repay for it. And you don’t have to tremble like that, I haven’t killed you yet. You will be my servant and the servant of my sons. I will even pay for this. I think cooking breakfasts and feeding my dogs isn't that hard, right? Well dear? Do you agree?"
