Phantom Dream maybe?

`Sorry,I have read everything except Phantom dream and Maoyuu Maou Yuusha - "Kono Watashi no Mono Tonare, Yuusha yo" "Kotowaru!"

It's a lot of violence, and nothing like Shojo (it's seinen), but Natsunokumo is a 'rare gem' of sorts. Serious, and has a good plot. Not sure if you've read it, but it's far from being shojo. Psychological, etc. 'Virtual Counseling' of sorts.

Kirai

Koi dano ai dano

the classics: Cat Street, Mars, Saiunkoku Monogatari, Princess (don't judge this one by the cover, it's actually good),

Joou no Hana, by the same mangaka Sonnan ja nee yo

Kingyo Sou

Six Half

Vanilla Ice, Oboreru Knife, Savage Garden and same author Flowers of Evil

Tell me if you need more, cause there are quite a lot of others in my list = =

Man is more ape than many of the apes.

I can only give you a tiny recommendation since I haven't read any(or at all) of what you're looking for since I prefer tragic stories, but I think Kieli fits in with the calm characters thing and the no blushing, but as for the open love thing, the story cannot relate. Gory as it maybe, however, I thought the romance was really sweet, but I have a different taste compared to most people...

I am vindicated!
I am selfish;
I am wrong!
I am right,
I swear I'm right.
Swear I knew it all along
And I am flawed!
But I am cleaning up so well
I am seeing in me now
The things you swore
You saw yourself...
