I watched this drama as each episode came on Netflix, and that sometimes really weakened my link to it. The drama has a strong start and it piques your interest. However after probably the first half, the plot gets messy and there are too many things going on which could easily confuse the viewer.

Few other problems that I noted:
-Joo Eun and Jung Hwan (Seohyun and Kyung Pyo) had great chemistry (check their bts and you'll realise why I say so) but their storyline was not well fleshed out.
-Joo Eun and Sophia Chung had an interesting dynamic which was not explored well.
-The show would have definitely worked better in a 12 episode format.
-I still have many questions that need to be answered but somehow I am still okay about that part.

Why I kept going:
-Strong Female characters who had distinct personalities.
-Sophia Chung was a SCENE STEALER! Whenever she would come on screen my attention would always divert to her.
-Sophia and Edward had the most interesting love line in the show (additional scenes of the two could have helped the show).
-Everyone acted very well from the main to the support cast.
-Funnily in spite of not having as many scenes as some other characters, the righteous policeman Myung Hyun really caught my eye. I was interested to see how he gets involved and helps our leads (also his dynamic with his fellow female officer was fun to see I was kind of rooting for them).
-I was curious to see how it all comes together.

Had I watched the whole thing at once I would have been more engaged and enjoyed it more! In spite of the problems I mentioned in the beginning, I still enjoyed the show.
