Hey guys!

I was wondering if any of you have any manga similar to those mentioned in the title (DC and Kindaichi shounen no Jikenbo), in that they center around a smart mc (must be male, so no Gosick) that goes around solving crimes using logic and his brains.
This question must have been asked hundred of times before, but what makes mine a bit more different is that i'm looking for something with a bit of romance in it. It doesn't have to be the main focus, or even a sub-plot, really. What i'm asking for is just some kind of attraction between the leads (blushing, jealousy.... things like that).
Their age doesn't matter, so don't worry about it.

Manga i've already read:
-Detective Conan
-Kindaichi shounen no Jikenbo
-Tantei Gakuen Q

Thank you

The male MC is definitely clever...
There is romance but a bit subtle and slow..
