I love romance and I don't think I hate any tropes. In fact, I think it's silly to hate tropes, they're only "tools" or "templates" for authors to use, nothing inherently good or bad about any of them. But I understand if people find some of them predictable or overdone. I only really hate it when tropes are done poorly.
Like when a romance story has "rivals" or a "love triangle" but the author clearly favors one couple over the others, and it's clear because it's always the main guy and the main girl who probably met in the first chapter. And it's tricky to handle this kind of trope, so I get why writers have a hard time with it. Like you can't have the other love interests be too likable or too good of a match for the protagonist, otherwise, it doesn't make sense for them to end up with the person they're supposed to end up with, but if they're too unlikeable or too bad of a match, then they're just annoying and you wonder why they're even there or how there's supposed to be any kind of competition. And of course, a lot of people don't like the idea of love being a "competition" to begin with, and they often ask why the protagonist or love interest has to end up with anyone at all, and they're right to an extent but like... where's the fun in that? I mean if you're gonna base a whole story around this kind of conflict, then you have to go somewhere with it. So unless the entire point is to say that not everyone needs romance, then that kind of ending would just be subverting expectations in the least interesting way possible. But there are times where I agree with those people, like when the story isn't a romance and the love triangle is forced in there.
This is something that even my all time favorite book series, Wings of Fire, is guilty of. In the second arc, there's these two guy characters that have a crush on the same girl and it's infuriating to see them fight over her when they're literally struggling to save the world. And the worst part is that in the epilogue, the author assumes we NEEDED to know who she'd choose by having her meet up with one of the guys and SAY "I choose you". LIKE THERE WAS EVER A FUCKING CHOICE TO BE MADE????? It's not even like she had much to think about, the guy she didn't pick became an angry, abusive prick, out of nowhere. Undoing his previous character development. And it's obvious that scene was only put in there so she wouldn't want to pick him. That makes it feel like she only chose the other guy because he wouldn't be a jerk to her, which, while fair, isn't interesting. Tbf, the author wasn't all that great at tackling romance in previous books, but in the third arc I think she does a much better job by dropping the "will they, won't they" drama of it all and just writing cute relationships that are just fun to read.
There's so much more I could say about all that, but I think I've said enough lol. My conclusion is that I only hate romance tropes when they're done bad, and they're usually done the worst in stories that aren't strictly romance and the romance is just a subplot, or worse, a sub-subplot.
