The chemistry, acting, scenery and staging are excellent. The music indicating loss becomes repetitive after a few episodes, but they spice it up with a new song every few episodes. I loved the first three episodes. The next five were almost as good. But Episode 13-19? 7 hours of nothing happening except going in circles? There is one revelation in that entire period. Please do yourself a favor and go to episode 20 from the change in relationships in 12. You won't miss a thing. If only they could've broken the mold and done this show with 11 episodes like Japanese Drama. Even then, that might be giving these characters too much time on the screen.
