Between this manga, "Comprehensive Tovarisch", "Flower and Star", and pretty much every single Shoujo Romance I've ever read but with a special mention for "Kaichou wa Maid Sama" for also starting us off with a hyper-competent heroine before putting her up against a love interest who is effortlessly better than everyone at everything everyday always forever I'm seriously starting to wonder if Japanese* Writers all have some horrible allergic reaction to writing couples who are actually, like, y'know, balanced against each other in terms of their abilities; couples where one member is not effortlessly better than the other at everything.
Seriously the only Manga I can think of off the top of my head in the Romance Genre that actually has a balanced pair is probably "Koi Dano Ai Dano"** because Kanoko and Tsubaki are both awesome and takes precisely 0% of anyone's shit. At least in "Tonari no Kaibutsu-kun" Shizuku had her cool-headedness and common sense going for her compared to Haru's off the wall weirdness, but in this one the effortless genius is still the more calm and collected one of the pair.
*This is hardly limited to Japanese Writers don't get me wrong but it seems especially common to me.
**Seriously this is my current favorite manga partly because everyone has something going for them, some legitimate skill that warrants their inclusion in the story or hidden character depths. Even the Ditzy Blond from the prequel has wizened up and displayed her own talents and character beyond "Blond and Cute".
