Bullying is a prevalent problem in many countries and its the bigger problem lies with the fact its a problem that is swept under the carpet most of the time. This drama holds no barred from revealing the impact of bullying has on its victims. The violence and abused shown is acceptable for my end albeit still disturbing on your mind and it's needed to show us that bullying is never to be taken lightly. Jung Haein carries his role so convincingly and he is such a likeable character even though he is not your typical hero but he held his moral grounds where its needed and defend his dignity. Sergeant Park with his limited power did his best to do what is right even though the outcome might not favour him. Lets not forget the comical sidekick Corporal Han , he has the best chemistry with Private Ahn n i secretly wished they can continue on to police academy n become detective partners where they solve the crimes together. The ending surely breaks my heart n i cried over the death sokju, when he asked them what have you done to stop it (the abuses) it hits right to my heart because in real life how many of us choose to close a blind eye to unfairness, bullying n abuse, in a way all of us are guilty of becomimg the onlooker which is the finale episodes title. The ending is tragic but it is the more reason why it tells us change must take place
