This doesn't cover nearly half of the series, in fact, it's very little of it. The Taiwanese and Japanese versions cover the entire story, and unless I'm missing something and they came out with more episodes, this was very short, and didn't wrap up the way it needed to. I've seen every adaptation of this series (Itazura Na Kiss/ISWAK/TKA, And this version), and this one is by far the worst.

I would highly suggest the Taiwanese Version (It Started With a Kiss and They Kiss Again) if you want the full story, or Itazura Na Kiss, which is the Japanese version, and also covers the entire story.
