Showmance: a romance/relationship that is started during the production of a play or musical. Very common in, but not limited to, high school shows.
Len (short for Lennon) and Eric meet under interesting circumstances. She has just been roped into being her friend's "Girl Friday" (AKA assistant stage manager) and he was somehow convinced by his twin, Sophie, to do the sound design for their high school's production of Beauty and the Beast.
United by their inability to understand musicals, the two help each other navigate the politics of the tech crew, which cast members to avoid, and the rules of showmances.
Although neither had ever heard of the word, they learn it's just part of the package when they find themselves in one. And just because the show is obviously going to be a failure, does their relationship have to be?
