I've only seen both NANA's and totally fell for him, especially in the sequel. He's so adorable, and there are so many pictures of him on-line, that it's basically hard not get attracted! ^___^' Also I'm planning to see Gakusen this weekend and Kagen no Tsuki after reading the manga. Sooo look forward to it.
Narimiya-san playing father? That's a must seen, thanks for mentioning it~!
