Im looking for a good shoujo where the girl isnt so oblivious to the guys feelings. I dont mind it the other way around though. And also the girl is maybe a bit crude ( because that often makes it funnier).

Im also looking for a manga where the girl likes the a delinquent or something to involve the Yakuza and stuff.

I don't necessarily mind if it is a bit smutty but i dont like it to the point that the guy is basicly feeling her up every chapter (like in huneyxhuney). It kinda makes the romance part of it bland and meaningless.

Heres a few:
-Limited Lovers

-Lovely Complex: But the guy, Otani, just might be the king of dense guys.

-Nodame Cantabile

Dunno about the second request. Theres Haou Airen but I thought it was pretty terrible. Junai Tokkou Taichou! could sorta fit. Sorta.

Hana yori Dango is the best example for a crude girl that do not get anything that has to do with romance. Very funny.

Heart
the guy is an ex-yankee.

I can only think of something for the second request
Delinquent Lesson title says all
You're So Cool
Heart no Kuni no Alice there is even the mafia in wonderland
Honggane
Cutie Boy

Tokyo Crazy Paradise?

The main heroine does get caught up with Yakuza. But it is kind of sweet tasting though.
