I know what you mean, I have an ex like that myself, hehe. I can still turn to him if I need help, but we lead totally separate lives.I also ship Sans/Frisk and Undyne/Alphys, but sometimes entertain the idea of mix-and-match for fun. Like lowkey shipping of Alphys/Sans (or Alphys/Mettaton) and Undyne/Papyrus. It isn't that I want to see them as actual couples, but as exes (in Alphys/Sans case) or on the side for Undyne/Papyrus - somebody needs to teach the poor guy a thing or two about romance. It's possible Alphys might not really object to that, she might even *ahem* set up secret cameras? You know, for observation.I've even made up some very nsfw story about that in my mind.
