Honestly, a pet peeve of mine when it comes to romance in shows is when there are two main characters that are planned to be endgame from the start, but the show runners don't want them to get together just yet so they have them date romantic false leads before finally ending up together with their "one true love." Even if I like the endgame couple, that type of writing dampens my enjoyment of them because I end up feeling bad for the people who liked the ships with the romantic false leads. Depending on the character, I also sometimes feel bad for the romantic false leads, because I would sure hate it if somebody was just dating me as a distraction because they couldn't be with the person they truly love. It almost feels to me like show runners write their romance plots like this to purposely start drama among their shipping fanbase, and as a shipper who's seen way too many stupid ship wars, it gets tiring.
