Part 5/10:
Parallel to Chi Sung's struggles in prison, Kim is making deals that further entangle loathsome elements of betrayal. After meeting Choi—a man he once sent a gang to kill—Kim agrees to help Choi produce a lethal serum. However, there’s a catch: Chi Sung must be eliminated first. Kim’s internal conflict highlights the broader theme of loyalty versus self-preservation, as he ultimately chooses to consider his interests over those of Chi Sung.
