Deep thinking

This series is one of the best I have seen recently. The story has many ups and downs. Sometimes action loaded and then quiet again. Haejo thinking about his life and coming to conclusions that fit in the end to others too.
I love the cast on the whole. They were all surprisingly good in playing a wider range of emotions.
Compliment to the director of the series. I think he brought out so many abilities in them. Sent me on a roller coaster of emotions too.
Will certainly watch it again.
