I just want to make sure I understand something before I decide who/what I want to write.

Pairings A/B, A/C, and A/D all have to be rare pairs, I get that. But, there doesn't have to be any romantic feelings between them, right? Say, for example, I use Harry as Character A and Katie as Character B, and I have them be just friends/teammates. As long as together they make up a rare pair, that's fine. Am I getting that right?
