|The guy in Magico (IWAMOTO Naoki) is one, such a cutie. I know some more, but I will update if I remember...
Edit: Wait, I know the following may not be your exact shy/awkward guy, but they're still cute: Kawaii Oresama would be in your ally (the blushing bit), as well as Kemono ni Botsuraku Ojousama. It's so damn cute that it will make you squeal (if you into that type of thing ).
