Its not romance, but have you seen Blue Seed. The couple of the main characters is reversed from your 1st gripe. The female is the awkward, shy, and dense one. The man is the "cool" character but is focused on other matters, aloof, and well... pretty dense in his own right. Other than that though, most of the other stereotypes do apply. But if you take the focus off the main characters (who are just teenagers and aren't all relationship things with teens pretty stereotypical and uninteresting) the adult members of the cast have far more interesting relationships with completely different problems. A manchild who never really grew up being thrust into a position of responsibility he's not ready for develops a reluctant relationship with a gun freak tomboy who has a problem with authority figures, a woman in probably not in her 30's yet who is seriously crushing on a guy easily in his late 50's, a career woman trying to reconnect with an ex husband to bring her family closer together.
Of course the focus is on the teen main characters who are annoyingly... teens. And just annoying in several other ways. And it isn't a romance story, what with all the monster fighting. But I like the team dynamic and pressures, the older animation cell style, the omaki shorts, and the tie-ins with many aspects of Japanese folklore. And... it ends. It doesn't draw out and go on forever. It tells a story, and finishes it.
It starts slow, but it does it for a good reason. The first dozen episodes each focus on a member of the cast to introduce them to the audience. And then the characters develop from there.
