Black Butler( work in progress)

If you were a demon being used to make a potion to stay young you would ask for a savior,right? Even from the famous tamed demon named by Sebastian, would you? Well I hate him but still accepted his help, weird isn't it? Here is the story about two demons and how a one sided love turns into equal love for one another between a crow and a cat, strange isn't it? Tell me about it, this is Sebastian's and my story so it's only right we tell you our story instead of others. So sit tight I, (y/n) (l/n), will start this interesting story.
