The story is half good and half bad; however, the acting is fairly good for a mini drama. To be specific, It was great up until around episode 15, 16 (where the ML starts smoking cigar with opium in it) to basically 23. The FL character was written with one-dimensional thinking (has no brains at all). For instance, in one episode after the ML is addicted to opium, she tells her friend that such outcome (inability of the ML to serve as the commander) is what 'they' want.
Now, I assume anyone who speaks such statement would be wise enough to know who would benefit from the ML not having the capacity to be the commander (Obviously the previous deputy commander and the brother). But no when the SML comes with the ring, she assumes that her husband killed her 'brother'. Additionally, instead of asking did you kill my 'brother', she just asks the ML if the ring is his. I mean the ring could be his and used by the killer since it can be stolen etc. FL never thought that far, she is easily manipulated. I was hoping for a strong story but it disappointed around the ending episodes. Just my own thoughts.
