Belonged to me first - Ciel x childhood friend reader

9 years ago you'd visit the phantomhives quite often to play with Ciel your best friend at the time. At first you had no choose as your parents were close with one another, but you grew friendly with each other over time.

But now everything has changed and there is another girl in his life.
But " he belonged to me first" and nothing can stop you from getting him back.
