I think I can speak for a lot of people – especially aromantic and asexual people – that romance (and sex!) are pretty boring subplots when they’re used constantly. In a book of my life, my subplot or plot B wouldn’t be about finding True Love or something like that…. so why does it have to be everyone’s?
Here’s am example: Jughead Jones in the Riverdale tv show. Jughead is asexual and aromantic, which is canon via the comics. So while his subplots in the show are 1) dating Betty and 2) joining a gang or whatever, they should be a lot different. Like…. food, because obviously my boy Jughead is in love with food more than he is with people.
So, I’ve compiled a list of other subplots that could be used instead of the really boring and stereotype-y “s/he finds love!!!”
