Have a love/hate (leaning towards hate) relationship with dense characters, specifically in romance cases. Like it’s okay for slight gag purposes, if executed well, you can get a few decent laughs out of the joke. But then there’s the point where it goes overkill, making the MC so oblivious to the fact that people like them. It becomes a lazy cop-out if used too much, like seriously, a character just confessed with no chance of misunderstanding and the writer still makes the MC oblivious and dense to the fact that it happened. No one can be this dumb!
