Usually in yaoi's the seme is the one who's really calm and serious or has a dark past that makes him mysterious, But WELL! I want a yaoi where the uke is that way. I'm looking for any kinda yaoi where the uke could match with this: serious, never smiles, calm, silent (maybe shy but not all blush blush, more like.. antosocial) mysterious or dark.
Maybe he just Is this way, or maybe he's like that because something happened to him or he's being bullied or whatever.
I'm so bad at explaining, but if anything comes to your minds, please let me know < 🙂

Edit: actually a Kind of example would be the uke in Negative kun to positive kun. the one with glasses of course 😛

Saezuru Tori wa Habatakanai practically fits your request perfectly!!
The main character has a damn screwed up past; and he's always putting up a cold mask & sardonic smiles. As for 'dark', well the whole manga is wallowing in dark and angst (a wonderfully twisted yakuza world) so there you go.

There's also Yuuutsu na Asa with a cold, coolheaded and somewhat manipulative uke. He's light years ahead your typical uke in terms of maturity and coolness, and he behaves in a jerkish but justified manner (yes, he's got a rather mysterious and darkish past)

Well, the main characters in Bronze & Zetsuai are all very twisted and dark. Add a psychotic, obsessive stalker of a seme and a reasonably naive kid and you'll get a story drowning in angst and drama. The uke is quick to turn cold and serious given the tragic turns of the story...

Dark/cold/angsty ukes are quite rare, but I love reading about them! Here are some more:
(Their personalities are duly justified given their crappy pasts and situations)

Zankoku na Kami ga Shihaisuru
Coponicus no Kokyuu
Zion no Koeda
Double Mints

And there are the 'normal' ukes who're just naturally cold/cool/calm and aren't as dark or freaky 😁 :
Koushi Kakka no Himitsu Gaikou
Renai Sousa
No Color
Yellow
Tight Rope

Simply another normal human being...

awwff thank you really much for the suggestions 😮 I've read a few of them, but there are also many I've yet to read to thanks a lot ^^!

I don't know if these apply, as they are not really dark ukes, but anyway...

In Hatsukoi no Atosaki the uke is quite serious, perhaps even too calm, and hardly ever smiles. It's not, however, as though he has a very dark childhood (although his past with the seme is heartbreaking) or puts up a cold mask. He's just really, really nonchalant.

He is the uke and behaves as such, although it is implied that later on they change roles

In Bi no Isu (chapter 1-3) and the sequel Kobi no Kyoujin you have another good example of a serious uke who never smiles, although this one borders the sadistic with his well-natured obsession with the seme (yakuza world).

Sayonara, Itoshi no My Friend another nonchalant uke, really cold and even a little meanie.
Crows ZERO dj - Borderless this is more of a cool uke then actually serious. But perhaps you like it as well.

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

I Really liked Crows and Bi no Isu, thank you veryverymuch :v
