I decide to watch the drama because the fighting at the begining was very impressive, however, it turned out that it was the only best sense throughout epi 1 to 40. Astory continue, it turns to be very difference. It really bothering with simple story line, an a simple investigation like any other drama that feel very mudane. The main lead is stupid and stubborn, keep waiting to die from the start til the end. It just a repeat of the same plot. The second lead is very annoying, and the chemistry is zero too! What should be more interesting is the third lead, then have a strong character, but been putting away from the drama and appear very less! Suck!
