When I started watching this, I really wished this one to be something I really wanted at the moment. When it up to the first episode of this k-drama it hooked me in a higher position, and I really felt that my heart skipped a beat. But I must say that second episode onwards the story was normal and there were nothing comparing to the first episode. I could not really explain whether it is because there were a lot of details in the first episode or rest of the episodes did not include enough details. Apart from that fall, when it's up to the story almost all of the incidents of the k-drama became upside down, but I really could not say that storyline was really matched with the incidents. First, they showed that the almost all of the crimes were done by someone else but finally they showed that all of them were done by the main male lead, there was something cannot be happened at the same time when it up to the crimes and crime prevention. There was nothing except to his own memory and there was nothing other than his own evidence and no one ever suspected him about anything, how can this be possible. I predicted it from the first episode only because of one of the promotional posters, there was one poster including main male lead sitting Infront of a victim and that small glimpse gave me such cliche and made me to suspect main male lead as the suspect but even though I watched almost all of the story knowing what will happen next but none of the incidents were really acceptable within the time that main male lead got. Simply put not only main male lead but also the god will not be able to do those each and every crime and crime prevention incidents at the same time especially in the TV SHOW episodes of that K-drama. It means the culprit do the crime same time and whining on the culprit same time and change each and every clothe and blood stain and cover each and everything very nicely while helping the cops to catch himself. Finally, he succeeded pretending the good person while ending the real good person's life while the brain surgery even though he is unconscious.IS NOT THIS RIDICULOUS? IF THIS IS NOT RIDICULOUS ENOUGH NOTHING WILL BE RIDICULOUS ENOUGH FOR YOU. Not just because I watched this with a hunch of what will happen, but the story was ridiculous with my hunch and finally my hunch of "main male lead is the culprit" became something ridiculous. But near the end they showed that my hunch is correct and culprit or the male lead have somehow managed to do each and everything at the same time. A viewer who did not have a hunch like above can really accept the fact that the male lead is the culprit but me who guessed each and every thing correctly and watched this with that hunch cannot accept that above fact because there were many falls when it up to that fact because I can clearly remember each and every incident with crimes very clearly because the story did not match with the flow of incidents. Somehow, I am not going to reject this as a crime thriller k-drama as I already said that the imagination and the story as well as the flow of incidents have their own perfections but when it came as one there were some unacceptable moments that cannot be matched even though we try hundreds of times. I really appreciate the perfect skills of the actors and actresses and their harmony and chemistry as a whole.
