The story was great but their maybe a confusion as they do jump 2 years ahead which had made me think that it was a boring drama but they do have flash backs and if you stick around a little longer it will be a surprise. It had a lot of sweet times but a lot of misunderstanding also (Typical love and hate plot). The overall story was quite surprising and had made me anticipate but i didn't really like the ending as it wasn't what i had anticipated for.
The entire acting was pretty good to me as it felt real and had managed to bring me into the drama since i was quite hesitant to watch it at first, but the entire cast had me hooked!
Music was fit nicely as it played appropriately and had no weird 'mis-match' of it in each scene.
Re-watching it won't be a problem but the large amount of episode can be quite hindering but if to really re-watch it, it would be an amazing dream again.
Overall, it was really good and it had many sweet and tearful moments.

I recommend everyone to watch it!
