I never watched the original series so no comparison on that part. This review may contain spoiler.

[STORY]
I love the story development and how it was not focus on romance. The romance part flowed along the story without any unnecessary drama. As I have watched many k-drama, I was bit sceptical at first that there would be too many cheesy romance in this adaptation. Man, this series didn't disappoint me. The tension, the twist, and the main story line were chef's kiss. The development of the main story was unpredictable so it kept me on my toes.

[ACTING]
The main leads had a good chemistry and looked cute together. Overall I didn't find any uncomfortable acting from the leads. Saint improved a lot here, he really showed a wider acting range and gave justice to Off's character. The actor of Dr. Jade is hand down the best actor here. He was able to convey the emotion perfectly even when he had less line. I will put him in my list of favorite sexy villain lol. The only character who peeved me was Junior, he was so annoying and overreacting.

[GHOST]
I think many people wary about this part, so let me give a bit review on it. FYI, I am scaredy cat myself >_<
The ghosts were quite scary and had good CG, like in typical Thai horror movies. I like that they infused Thai culture and folklore in some of the ghost story. Overall, the ghosts were still bearable and I didn't get any nightmare afterwards lol. It was scary at first, but you got used to it after a while. So don't make it to be something that hinder you to watch :)

In short, this series has good story line, acting, pacing, and editing. I hope there will be season 2 when they explore about the devil's fragment in Off's body, it will be cool to see Off's struggle to tame the devil inside him and I kinda want to watch Saint act as villain. But seems the probability of S2 will be very small as this was an adaption to begin with. Overall, I really enjoyed to watch this series and may rewatch it soon for the details.
