The black chess piece (a ciel x reader)

When you are in a ball you befriend a boy named ciel. He soon finds out what you're father has been doing. So he lets you stay at his place for a few months. You soon meet ciels betrothed Elizabeth. You become best friends with her. But only soon to find out ciels little secret...;). Oh I almost forgot! When it comes to the author owning kuroshitsuji, I am not the owner! ~Maury hahaha I also do not own mah peeps (you guys)
