ships that you thought were canon before seeing a show/game/ect. due to being popular with fans, but then realized they weren't when you actually played it?

i think every kid had this experience, but when i was younger, there were some ships i'd see everywhere in fanfic or fanart and just assumed happened in the show without actually seeing it. imagine my shock when i'd heard so much about "bride of discord" as a kid only to find out it wasn't a real episode and fluttershy wasn't really married to discord. has this ever happened to you? are there any ships you mistakenly assumed would be canon because of how popular they were?
