So I read today that "Cat Street" by Yoko Kamio (of Hana Yori Dango) is going to be an NHK drama.
"Cat Street" is... I don't like describing manga stories (because I suck at it), so please look at this site and search for "Cat Street."
Anyway, Keito (Kate?) is going to be played by Mitsuki Tanimura, who did the voice for Kaho Fujitani in the anime movie "The Girl Who Leapt Through Time." She's the one who confesses her love to Kosuke.
I hardly watch Japanese dramas anymore, but maybe I'll watch this one. Depends who is writing the script, I guess...
Here is the manga cover for "Cat Street."
By the way, Yoko Kamio chose to have Kaito's hair "white" because she was tired of coloring in black hair, because of Tsukushi and Domyoji.
