Narimiya Hiroki is very sexy. In this ad, you can see him evolve from Neanderthal to Japanese idol. The image to the far right is perhaps too processed. I think I prefer him in the second-to-last stage. Do you prefer Narimiya-kun rough or doll-like? I know, most of you will prefer these images of Narimiya-kun naked on a bed.

I have just been watching him Stand Up from 2003. He was incredibly dorky in it!
the pic, third from right, looks like current Keanu Reeves!
I’ve seen him in several dramas – I think the last was Bloody Monday alongside the eternally beautiful Miura Haruma – but I will somehow always love him as Udayan from Stand Up. As Kathryn above said, dorky, but totally adorable. Though if he donned a top-knot and did some sort of rough samurai thing, I wouldn’t be at all opposed to it~
