Well... yes and no. Lucius/Severus is my OTP, however, it doesn't exclude the deliciousness of Percy/Severus, so Percy/Remus is just a natural progression, I suppose. (Severus/Lucius/Percy isn't too bad, either.)
Then again, Percy is versatile. But you really are doing a very good job at convincing me that there needs to be more Percy/Remus fic in fandom. (And moar comments! I've been away from fandom for a 1.5 year or so, and Christ on a hobby horse, people are getting lazy.)
