This trilogy is heavy. Friend (2001) sets everything up perfectly – the friendship feels genuine at first, then slowly crumbles. I respect how it doesn't give easy answers. No one is fully good or bad, just people making bad decisions under pressure. Lee Joon-Seok's story breaks my heart the most because he never really wanted that life but couldn't escape it. The acting is top tier across the board. Watched it dubbed once by accident and switched back to subs immediately – the emotions get lost otherwise. Tubi has it free? Downloading now. Thanks for the detailed review, makes me want to marathon all three again.
