The first 4 episodes is quite interesting, mysteries, action, drama. But it started to go downhill pretty fast. The writer is the one to blame. Characters were written inconsistent and shallow. Reporter /best friend of 13 years, take on an unknown tip and jump straight on a witch hunt without doing any due diligence. Not once ask, what is FL motive, what purpose, who benefits for the murder? If I were to get some unknown tip of my BFF doing shady things, I would have a hard time to belive it. How can a reporter not have such basic analytical thinking? and FL supposed to be so in love with her husband, can just flip off the love button and be so calculating cold, without any internal conflict is beyond me. K-drama quality in recent years is declining and the script/writer is always the culprit. So sad for all the talented actors.
