original adaptation is best ！ not great fan of yankee or gang dramas but I like here how it shows Yu transforming as an individual and also realising importance of friends both personally and in fighting 〜 and at a deeper level this drama shows a man in a real fight for existential survival and this lifts this drama above simple entertainment：he fights or he's bullied、 but even fighting and winning the battle never ends as life itself is a battle〜don't agree this is too short it is just right to ensure the pace and development of the story without useless repetitions of fights just for their own sake and for me there is no boring episode〜fights are exciting but scary〜 theme music great🔆
