   Summary

   He's not technically trying to steal his bestfriends boyfriend if his bestfriend is paying him to be his boyfriend...right?

   or

   James Potter and Peter Pettigrew have been friends far longer than they've been colleagues. When a promising promotion opens up, both boys are determined to do what it takes to prove they're perfect for the job. James brings his family's legacy, a lifetime of trade secrets, and the charming personality that has won him everything he's wanted since birth.

   Peter brings his unwavering will, a decade of apprenticeships, and Regulus Rosier, an elusive escort with familiar eyes, a penchant for getting under James' skin, and far too much knowledge of the inner workings of a business he seemingly has no part in.
