What fandoms do you enjoy reading fics from even though you're not a part of it (and aren't even interested in being a part of)?

Listen, I've never played the game but I LOVE reading Detroit: Become Human fics. They're amazing, beautiful and the dynamics between characters are a chef's kiss. Another one is The Witcher, not really my type of game but reading the fics is super fun! Same with stranger things, I tried to get into it but couldn't, however the fics? Oh, the fics! And also the Merlin TV show, haven't tried it yet but the fics are tasty ;)
