I have watched the korean and now the thai version. To be honest. I liked this version much much better because it has a more natural feel to it.
The writers have done a very good job in rewriting the story and added parts that make it more relatable.

Liked
All except for the annoying parts of the story such as the egoistic characters grantfather, father of the FL and ex-girfriend. But in the end they repent.

Liked most
The acting of all actors were very well done. Chemistry between the main leads was great. Enough scenes to make you see the development of their strong love bond.

Rewatch value
Thumbs up. As I wrote before. I liked this version better than the korean version. I can watch it over and over again.
