She Loves Me.

Amalia and Georg work together at a modest Hungarian perfumerie, and have disliked each other from the very beginning. He thinks she's stuck up, and she thinks he's arrogant and mean. But each rapturously writes to a lonely hearts pen pal when the workday is done, and it doesn't take long for the audience to see that they're in love without realizing it. Originally live-streamed by BroadwayHD, then broadcast as an episode of the PBS series "Great Performances" (season 45, episode 3).
