Wow amazing ending

Wow the ending such an amazing plot twist.It makes soo much sense that it’s the police officer. How is it possible that there’s no footage of other people entering the club. No search for the murder weapon, no search for DNA around the crime scene. It makes sense that it was an inside job in the police station. The motive isn’t quite clear though like why kill yeo reum? There’s no motive to kill Seon-A either was the police officer Kwak in love with her or what?? Writers make sense.!! I’m disappointed in who the killers were. I guess the writers just wanted someone who the viewers would never suspect. I hope they explain more in the next episode.
