I think it's a mistake to take kdramas out of their original shape,specially the way Netflix did;cause it shows that the channel has no idea with the way these dramas work.
The writers had to cut so many aspects of this story,that is a new topic in drama land,just because of the 8 episode rule that Netflix had.What is the result of that? The show ended with a cliff hanger making us wait for season two.They could've at least give answers to some questions but were more like "No,lets finish this in the most incomplete way."

The acting is not bad,but it's not something amazing either.you could've either sense the lack of experience in the two main leads or maybe that was the way that the director wanted them to act,either way it wasn't perfect.

Another unbelievable fact for me is the way that this drama is so bad at the music and OST.

But what is strange and in the same time good,is the way the whole series wants you to stay and watch what happens to the characters.so is it worth watching? If you have time and want a good love triangle,why not.
