Bearing in mind that I would not dispute a claim that I have terrible taste, here's a random slice of shounen/seinen romcoms/slice of life that I enjoy(ed):
Seishun Forget! : Girl forgets everything that happened the previous day overnight, unless it was especially fun. Boy falls in love with her at first sight, she agrees to go out with him, shenanigans ensue as he attempts to make her actually remember him.
Suki x Suki : Girl has massive crush on boy, too embarrassed to do anything but blow him off. Gains the power to turn invisible (and is no longer embarrassed while invisible), but he can still see her. Shenanigans ensue when she doesn't realise he can see her, but he refuses to tell her because it would be too embarrassing. Very shounen-y, I wouldn't swear to it being any kind of objective "good", but it's fun.
Pashiri na Boku to Koisuru Banchou (The Lackey and the Delinquent Leader in Love) : Delinquent boss girl asks severely bullied boy out, he (completely legitimately) mistakes it as an order to be her errand boy. Shenanigans ensue.
Senryuu Shoujo: Girl only communicates through 5/7/5 poetry. Boy looks like a delinquent, but has reformed in the name of poetry. Slice of life shenanigans ensue. Currently pretty popular, partly thanks to the anime adaptation.
Tonikaku Kawaii (Fly Me to the Moon) : Girl saves boy from being killed by truck. Boy falls in love, asks girl out. Girl agrees on condition he marry her, vanishes. Two years later, reappears, they get married, shenanigans ensue. May cause mild diabetes.
The genre is not exactly starved for
content, it's usually just a question of filtering out the incredibly generic/good but uninspired works from the rest, or finding less mainstream ones that you like better*. I also don't really have a record of most of the completed series I've read, since I tend to tear through most of them too quickly to need to bookmark them. >_>
* This list doesn't really have any conventional "harem" stuff, for instance, because I personally dislike it. It's a biased list.
