It was a very good movie the only thing that was frustrating was that we didin't hear Koyuki's voice, never. Even not in the end. But I could tell it was like in the Manga and Anime, even if there were some scenes missing, what is totally normal ;)
Best drama I've ever seen, it was the first where I could tell : that could really happen in reality. It is simply realistic, and the actors made a fabulous job. I was at first septic, but after a few minutes of this drama, I was captivated by it. I think a good actor is only good, when he makes you pass by all the feelings. And those actors made it happen.
My first Drama with Her was A love to Kill, and it was wonderful, i cry so much, you are so right with what you said about the chemistry between the actors, and My girlfriend is a gumiho, was wonderful and funny. She is a very good actress
