The actors did a great job especially Lee Tang as he is shown to cry as people he cared about got hurt but also how he had to grow up too fast because of 1 accidental kill. In ep 5 it would've been nice to see him getting the new haircut as it took me a while to realise who he is as he looked so different.
Song Chon's story wasn't explained as clearly as I hoped as I still don't understand how he intertwines with everyone's else story as what is his motivation and how he got to that point.
Nam-gan is a cop who needs to rely on others as he is the lone wolf.
It just got messy to quickly with too many characters coming in
