This is great drama brilliantly crafted all parts of the plot came together and worked out with surprise outcomes to the end〜 I binge watched last 3 episodes　〜but do not expect the usual school story of romance, bullying social and domestic problems、 this is tough unforgiving bloody and violent and shows the sordid underside of society with these not- yet -adult school students plunged into the adult storm of reality。 Some characaters〜 not the main leads〜 I found difficult to have any empathy with - these were just childish and caused all the trouble because they were the most confident they knew it all but actually least able to handle the dangerous world they trod into but I accept the actors played the part well to create those feelings in me. I do not think there was a single person not playing their part well. Knowing the plot I will not rewatch 〜only need one watch for message to hit through but highly recommend if you have strong stomach and strong mind to deal with this drama.
