Heard there was a lot of production issues with the drama, and it really shows nearing the end. First is how ridiculous the plot points are being tied up and many are forgotten because they have to start touching on the main plot which has barely moved till nearing episode 30. Then every episode from 30 onwards is so rushed with many scenes just randomly cut into without much explanation, and the finale was just disappointing felt like a waste of time sitting through all 39 episodes just to see how 40 ends. Poor adaptation overall the actors and actress honestly are the one that carried the show and why most people finished this series anyway.
