[Crossover] The Black Contract

At the Eighth Pawnshop, what do you want? To get it, you must trade something of equal value! Your eyes, your brain, your feelings… or even your soul! There's nothing they can't do here, only things you haven't thought of. It all comes down to what you're willing to give up and whether you want it badly enough. So, then, what will you choose? ↓ ↓ ↓ A fanfic based on The Eighth Pawnshop. Han Nuo and A Jing do not appear. The female lead is an original character. If you like sweet, naive Mary Sue stories, click the X and go elsewhere. Things to know before reading: 1. This story's values are questionable, so read at your own risk if that's not to your taste. 2. The characters may change, but their core remains the same. The female lead is not soft-hearted. 3. There is a pairing.
