I want them all to collectively grow a pair and start being bold & emotionally intelligent.
I'm fine with some differences and personalities between MC, but if they are complete idiots I don't want to read a romance with them, and if they are not complete idiots I don't particularly like when they suddenly pick up the idiot ball and run away to never come back. (Except when any whiff of threatening romance is over, when they suddenly return to normalcy.)
Boku no koko is one of another class of manga that is almost as common - the one where the first 3-4 episodes set a tone that is then lost in favor of something else. (Or at least gets skewed away into something notably different. And some of those are pretty good, like Boku no koko that has a very nice teen romance with imo better handling of the different problems. Also the author did a very nice and smart move after a while by making twitter episodes set apparently half a year into the future, so the 'trying to find a romance' drama gets some interspersed 'ooo, they're basically a couple already' slices which also helps one to forgive their current problems, since 'oh, it'll work out sooner or later, or so it seems'.
(A couple other stories that start out seeming one way but then snags you with their storytelling ways are Rokudou no Onna-tachi, and the possibly infamous Kage no Jitsuryokusha ni Naritakute - which I thought would be the worst isekai story ever, but within a few chapters it managed to subvert my expectations excellently.)
