Whoa I didn't knew about the anime, I gonna watch it for sure, and I also know about the live action,but I don't know, there is something weird about these japanese shows, I can't explain, they are just not the same thing as the mangas and animes, you know? Oh, and about Kitami and Anna, they already got an special chapter, is an christmas special. But is still in raw format. here:
[link] For what I understood, Kitami wants to give Anna an christmas present, but he just don't find the right moment,so his friends try to help, by inviting Anna to Kitami house to help on the Christmas decoration, but they don't get one moment alone at all, so when Anna is about to leave, Kitami little sister takes the action and says to her that Kitami got a present to her, but even tought Anna gets obviously flattered, this romantic moment is ruined when Anna see that her present is extremely uncute, it's just great.
