After the first part, this is my review : It is without any doubt a wonderful series. You are not bored a second, it is always in motion, the casting is great, the plot is original. All this is made with several tough subjects, and they managed to deal with them pretty well.
Yi Jae will face several deadly situations (all of them are original), can he change this ?
Obviously some scenes are difficult to watch but this is the price to pay to have the maximum realism.
Seo In Guk is awesome, as expected, but the entire cast is compelling (always a pleasure to see Kim Jae Wook after Alchemy of souls).
