Read Webtoon Baek XX online in English. Also known as Mr. Baek, BaekXX, and 백XX.

Baek Yisoo and Baek Dogyeong were born as twins, but their lives could not be more different. One serves as an elite HID agent trained to move in the shadows, while the other rules the streets as the boss of a powerful Seoul syndicate. When betrayal, death, and hidden agendas collide, Yisoo is forced to throw away his own name and step into his brother’s dangerous world.

The tension comes from more than fists and knives. Every alliance has a price, every smile can hide a threat, and Yisoo must survive among criminals who follow rules he never lived by. As he searches for the truth behind the chaos around him, revenge and identity blur into something far more complicated than a simple undercover mission.
