The drama was wonderful. the story line was good but they need to improve the execution of the drama. the acting and cast are good and I ended up with a box of tissues to wipe my tear in the last episode. but the ending is incomplete the drama has an open ending which disappointed me. the ending spoiled everything but other than that this drama is wonderful .
I will recommend this drama to people who don't mind open endings only. the plot is an interesting one and The leads and rest of the cast are experienced and good-looking. Plot holes appear and the investigation drags on.
I think that because of the the production team the drama ends up being average.
