Cartel

Won Do-Yun, a boy left alone in the most run-down neighborhood. Though he had talent, the world dragged him down. In a world controlled by a massive cartel, he realizes that the higher he climbs, the deeper he sinks. Won Do-Yun ultimately makes a choice: the abyss over the summit. And he stands at the very center of the cartel, determined to bring the massive organization crashing down.
