I watched the original Korean version and I like this Thai version much more.

The chemistry between the main leads is off the charts! I really love their banter, their sweet moments and them just being together in one screen is enough for me to watch this again.

What I did not like? The supporting actress/third party  - she is way tooo old for Mike! They should've picked a better, much younger actress. She looked more like an aunt than a love interest.
The second male lead almost gave me the 2nd male lead syndrome. And I say almost, but not quite. The leads really do belong to each other and the chemistry was unequaled!
