Its a Japanese drama on par with kdramas.

Although it was a rushed drama, and message at end not so easily understood by all, its only very few of Japanese drama I was hooked to till end, cinematography was lot better and there were no glitches of absurd non sense plot holes in drama. A nice piece of fiction I would say. If show was little longer with more of their characters explored. I would have rated it 10.

Should you watch it?

The drama had some awesome opening, with stellar cast and nice music sometimes but towards the end it becomes a total absurd. A father stealing his son's crush, dating his girlfriend in front of him makes no sense. MJ drill got no satisfactory end either. And bo hoo's beginning her carrier suddenly vanished, and it was left for that absurd repeat kiss between two protagonists. MJ and Ji hoon had nothing but a total waste role. It was as if like either writer was confused or there were more than one writer for story.

chemistry between cast is great

Entire lead cast is good looking in looks. You don't get bored of looking at their faces. And their acting is pretty good too.
Although there are antagonist in plot but they are not bad to the extent you feel overwhelmed by the darkness in story. Its pretty light hearted. Although there is political rivalry and there are more of nice dialogues between hero heroin. Although you feel like its so obvious, how can she believe such lies, you still wanna watch it as it is light hearted and has a warm feeling to it.
