Hey, i'm looking for a manga where the protagonist's love interest is a serious, intelligent, near perfect(in looks, grades, achievements), straightforward and honest heroine (and the MC gets with her at some point in the manga).

Here are the kind of heroines i'm looking for:
Yukinoshita, Yukino from Yahari Ore no Seishun Love Comedy wa Machigatteiru.
Makise, Kurisu from Steins;Gate
Igsem, Yatorishino from Nejimaki Seirei Senki: Tenkyou no Alderamin
Tsukimori, Youko from Gekkou

Requirments:
Good plot - Preferably like the above mentioned novels(which I consider to be a little more serious plot-wise).
Protagonist is definetly not dense/stupid and has common sense same with heroine
It is either fully translated or it is being translated with frequent releases(and not dropped by either the author or TL)
Preferably finished TL or at least finished in country of origin
Preferably they don't get together right at the end and the manga finishes right after
Seinens would be good but not a requirment if the plot of the shounen is good.

Don't want this:
BL/yuri/gender bender/shoujo/josei
Harem
