2 Works in Miss Saigon - Schönberg/Boublil/Maltby
RPF but with fictional characters :D Ha. OK so I guess it's not real RPF but what I mean is it's not about the characters themselves, it could be about any two actors who play the parts of Kim and Chris. Unbeta'd scribble after listening too much Miss Saigon. My cheat for how to give Miss Saigon the Happy Ending I know it can never have.
When war-hardened Sergeant Twilight Sparkle encounters orphaned friendship worker Fluttershy in a friendship emporium in the bombed-out town of Ponyville, they and about a dozen other characters take part in an elaborate adaptation of the first part of Miss Saigon.
