I think I ship Kristy/Sunny. (Okay, so there is a very short list of people I don't ship Kristy with. Why am I like this? I don't know.)
Anyway, the problem is that I don't feel the need to write Kristy/Sunny fic (at least not right anyway,) because I have it.
It's called RENT.
Joanne/Marueen is my Kristy/Sunny fanfic.Eta: Sunny is totally bi by the time she gets to college. This is not a question in my head canon.
