I honestly knew from the very beginning who would be the predator but it's still very emotional and painful to watch the family of the victims suffering and how the victims died. This is a very emotional story and the plot isn't totally expected. I wasn't expecting all those truth that were revealed in the end. This drama totally kill it. The acting are excellent as well. No words to describe how incredible this drama is. I can't assure you won't regret if you watch this drama but I would really recommend this drama for all the thriller/ psychology/ mystery/ crime/ investigation drama fans' out there.
