Maybe an obscure couple of pairings, but any Michael/Meg or Gavin/Lindsay?
For Michael/Meg I could only find one fic unfortunately (although I’m now suitably intrigued by the pairing), and for Gavin/Lindsay there didn’t seem to be anything that didn’t involve them being in a love triangle/square with the other two! I’ve included a few Megvinsay and Mavinsay for your reading pleasure.
