First of all, it's Japan. So everyone should be prepared. In comparison with the Korean version, in budget and 'richness' this drama fails. However, the acting is marvelous. The unknown before actors make a really good impression. The actor, who plays Irie Naoki is truelly natural, despite his age, he looks exactly as I imagine the real Irie Naoki. The difference in age between the main actors is not the problem at all. I personally was shocked, when I found out about it. And this drama has its own atmosphere and style. I don't remember myself being so exciting during watching Japanese romantic comedy, cause I usually escape this style. Well, I am only on the 5th episode, so that is not the end. Hope there would be more thrilling and astounding things and surprises.
