Actually, there is a fic that *sort of* has that plotline - it's called 'Mrs. You and Me' by El Juno, and I really love it.

But I was thinking more of something from the girl's POV. So often in fanfiction, our fav boys are plagued by the fear of coming out, of being rejected, and/or of the girl who just won't leave well enough alone. It'd be interesting to write a female perspective with the same sort of issues in mind.

Just a thought. ;) Dunno if I ever will; we'll see.
