Fans of this drama will not want to read my review. If I were to summarise it in one word, it's "overrated". Having watched Rooftop Prince before this, I was very eager to watch this show especially after seeing that it has an even higher rating than Rooftop Prince, which to me is one of the best drama I ever watched this year. But when you have high hope like this, I guess you get disappointed more easily. Let's talk about the good point of this drama first - the excellent chemistry between the two leads. Yes, this is what kept me going and why this drama does not score even lower in my overall rating. Their chemistry were so good that if anyone has told me that they are real-life lovers during the show, I would have believed it 100% (yes, and it turns out that they are!). If you want a show with sweet romance, this is really an excellent show! Now onto the bad point - the plot! I felt the starting was a bit messy and confusing especially the josen period, but that is still tolerable, what is not quite tolerable is the inconsistency of the time-travel element. At first, it was very clear how the time travel could be activated, however midway through the show, it seems that some instances of the time-travel does not seems quite consistent, there was a particular part in the show which makes me felt like a 3 yrs old child, i.e. being cheated in the most illogical fashion. (I shall not say which part it is due to spoiler) Basically, if you just want pure heart-warming romance, this is the show for you, but please do not apply any rational thinking while watching the show, just follow the flow and you will be happier. I mean, even though the concept of time travel is already irrational in the first place, but if you were to compare for the sake of comparison, in Rooftop Prince, you have a much more believable and convincing plot to the time-travelling irrationality.
