The drama seemed promising at the beginning then it went too slow. I watched until eps 11 and skipped to the end to find out the murderer. And realised they really had weak plot.
Spoiler : if Mr Lee already had all the recording and proofs from the begining, then the murder is really unnecessary. He just need to send them to media. The result will be the same.
And with all the powerfull men involved , isn't too convinient to let Simok took control of the investigation just like that?
It is just not make sense. However all of the actors doing good jobs in delivering their roles
