Kind of agree with the Ueno and Toma pairing. Personally, not saying that it doesn't suit her, but her hairstyle somehow doesn't fit right. I mean it looks fine on her but it makes her look maturer. Much suitable for Oguri Shun's character. Hope that makes sense.

--SLIGHT spoiler--
I don't know how the manga is but Shun's character is made out to be super smart and yet... he goes and inspects a body with his bare hands! Makes me think the story-people responsible for such things didn't notice this little detail. I mean, he's yakuza and therefore his fingerprints would be on the database.. so I'm presuming he should be more aware about what he touches, esp. at a crime scene.
