Jang Han-seok is the true power behind the Babel Group, a young chairman who hides his ruthlessness behind a disarming, boyish charm. For much of the early story he operates in the shadows, letting others take the public heat while he pulls the strings.
As Vincenzo closes in, Han-seok steps into the open and reveals the full extent of his cruelty, a remorseless schemer who treats human lives as line items and violence as a business tool. His chilling lack of conscience makes him a uniquely unsettling antagonist.
Their escalating duel becomes the spine of the series, a contest between two men who both reject conventional morality, with Han-seok serving as the dark mirror that justifies Vincenzo's own brutal methods. His downfall is the prize the entire narrative drives toward.
