This is a remake of the Korean drama, but I haven't watched the Korean version. On its own, the Thai version is good.

Namtan is convincing as the twin sisters with different personalities, Meen and Mind. The rest of the cast is really good too, especially Jamie as Kat in a supporting role. Krist is good as Natee though one may wish that Natee were a more multi-dimensional character.

I'm not sure how much credit goes to the original Korean scriptwriters, but the story is interesting. The plot about Mind as a badly bullied girl losing her memory and being taken as Meen is complemented with a suspenseful subplot about the death of a girl called June (Meen's friend).

The series seems to be targeted at teenagers and surfaces a lot of issues confronting teenagers, from school bullying to parental expectations and stress over grades. This series contains some of the most astonishingly terrible examples of parents I have seen (particularly the parents of the bully, Tida). In fact, for a large part of the series, Natee's father and Meen's mother are the only truly good parents. Ironically, Meen's mother does not even have any biological children of her own and she is a better mother than those who have given birth to their own children.

It is not very convincing when most of the parents (e.g. Pete's mother and Gun's parents) become better quite suddenly, and there seems to be an excessive eagerness to send a positive message in the last episode. This undercuts the seriousness of the problems in society, such as the bullying of an orphaned girl to the point where she attempts suicide. However, this doesn't affect the show much.

I believe the weaknesses of the original Korean series are present here as well. The depiction of Gun seems a little formulaic (the second-male-lead syndrome strikes). Kay has performed the role of Gun well, but Gun doesn't seem to contribute much to advancing the plot (especially in the later part of the series) and appears to be merely there so that the female lead has not one but two ridiculously wonderful guys as suitors.

While the plot and acting are good, there could perhaps be more distinctions between the Korean series and the remake. From the comments I have read, the changes are minimal. Working towards a different ending would have been interesting. For someone like me who has never watched the Korean version and don't intend to, however, this is still an engaging series.
