In the first 3 episodes I thought about dropping this drama, because it was very messy and confusing from the start, plus the investigation was so sudden, suddenly checking on information A, suddenly checking on information B ,,,(when they checking information about what happen 20 years ago,,, and about water pump) And the evidence or information they get too not explained very detail,, and and they can go straight to the next destination without being explained in advance where( case prof.nam), sometimes confusing because a criminal has many hiding places


plus they added a backsound that seemed tense, but at that time what I felt was not tense, just confusing and and dizzy

and when the detective Han's subordinates reported the laboratory results, it was also confusing ,, because there were many cases and piled up so didn't know whose report was read plus the confusing subtitle






#### nice part######
The highlight of this drama is ,, the main villain who is hard to guess until the end ,,,

In one episode I saw a shadow and had suspected that the villain was a ........... (forget what episode) ,,, and also suspected very many people, even though I knew the gender but who was the real eraser unpredictable


#bad part of story##

1.ep1 , Since the beginning there is no evidence that Yoon Ye Rim's case related to serial murder is being investigated, but Dongbaek can immediately start the search from investigating the serial murder case.
Because it can only be truly concluded that Yoon Ye Rim's case was related is when episode 5, when Det.han saw a point of similarity about they case

2. Suddenly two detectives of Dongbaek's friends investigated about the water pump, but it was not clear where it was because it was not clearly stated,, plus when they suspect Yoon I Tae ,, the place Dongbaek & Hansunmi go to is different

3. Episode 8-9
was the most difficult episode to understand, very brain-draining ,,,, the words they said, and the place they were going to was unclear ,,,, and when the flashbacks of jinjaegyu's house they mean is different? But from what SANG HA said, the house of jinjaegyu in past was the same as now, so which house was the house with the caretaker?


4. and i don't understand what is the purpose of eraser provoking dong baek and hansunmi?
