An emotional show. Good written story. There are still some fast forward events, leading to some awkward end of those events. For example, the president suddenly became regretting of his crimes and come to apologise Hae-seong, pretty much strange.
But overall, Yeo Jin-goo's impressive acting took me much tears. As well as the music. Cannot hold tears when i remember those sad events even after finishing the show.
I watched Circle: 2 worlds connected and Hotel del Luna which Yeo Jin-goo is leading role too. These 2 shows have great story written too. Maybe after these is Absolute Boyfriend? He pretty much like leading role in science-fiction shows.
