I think this drama is simply great. it posed moral questions to the viewer, itt made you think more and more, you wanted to be part of solving the mysteries, you see the relationships in a working space of a group of people who you'd think they'd not get along well. generally the acting was great, definitely convincing different styles. the inspirational part of this drama made you think deeply with every episode. I think that if you are someone who likes to think when watching something then this drama wll definitely be appreciated.
