I don't think I've ever read a fic based on I've Got A Crush on You, which is one of my favorite episodes.
It's not one of my favorite episodes, which perhaps (or perhaps not) explains why I've written not one but two take-offs of it.
I've got an elseworld called
Hearts Divided that starts out in IGACOY and then veers off.
I've also written a more-normal-ish rewrite called
I is for Illusions (Working title: "I've got a Crush on Two"). That's actually a sequel to
H is for Hubris , which you should read first, but hey, it's short.
