This is my first completed k-drama and first review so here's my short take on it. Contains spoilers.

The show has some really great actors whose acting drags you into the story especially Go Min-Si (plays Yoo Seong-A). She really managed to nail Yoo Seong-A's psyochopathic nature, not only through the emotional indifference and creepyness which she portrays. But most of all through the moments when things don't go her way and she shows her emotions, for example when realizing that she might be put in jail by the evidence that Jeon Yeong-Ha had or the times when she was face to face with her ex husband.

Even though the acting was great, you can't make a good story without great writing, and it delivered. I believe that the writing was particularly good at illustrating the consequences caused by different ways of reacting to an event, which in this case was the murder at the motell and then at the vacational home. At the motell murder, the case had a very speedy conclusion and the murderer got caught rather quickly. The consequence of the killer getting caught was that the motell then got associated to the killing and who would want to sleep at a motell which people have died at? This further on leads to the ruin of the family owning the motell. The other side is the one that Jeon Yeong-Ha chose to take, which was to look the other way and try to forget the incident. This in turn allowed him to keep having customers visiting the vacational, but also allowed a killer to roam free, which put his loved ones in harms way.

The conclusion that I drew from the different incidents was that no matter which way you react, if you're the frog that gets hit by the stone, there is no easy way to recover.

Anyway pretty good show for my first completed k-drama, it left some loose ends and the switch between timelines was sometimes a bit odd so I'll give it an 9/10.
