Mr. Baek

Baek XX; BaekXX; 백XX

Baek Yisu lives in the shadows as an elite agent, trained to move through danger with cold precision. His twin brother, Baek Dogyeong, walks a very different road as the feared boss of a powerful Seoul crime organization. When betrayal destroys Yisu’s life and drags his brother into the same storm, he is forced to abandon his old identity and step into a world ruled by gangs, politics, and revenge. Wearing his brother’s name, Yisu enters the underworld with a soldier’s discipline and a blade-sharp purpose. But every move pulls him deeper into a game where loyalty is fragile, enemies hide behind rank and power, and becoming someone else may cost him more than he expects.

An elite agent takes his twin brother’s place in Seoul’s criminal underworld, chasing vengeance through a brutal world of gangs, betrayal, and hidden power.
