It was just a day in Hogwarts, the Gryffindors and Slytherin were having their potion class together. Everything was going well, untill Harry J. Potter and Draco L. Malfoy were paired on a lovely potion task. What will happen?

A Kuroshitsuji (Black butler) story about a modern Ciel and our Sebby as a demonic teacher. It's my first fan fiction and I hope you're gonna like it! It's a boy x boy story so if you don't like don't read it.
