It doesn't matter to me because I have seen every other version, save one, anyway. Honestly speaking, that was the version I enjoyed the least, especially the second season. The casting had a lot to do with it. Have you seen the other versions? If not, here is a list, in order of which versions I personally enjoyed the most:
Playful Kiss (Korea)
It Started With a Kiss & it's sequel They Kiss Again (Taiwan)
Say That You Love Me (China)
Kiss Me (Thailand)
