Zero Day Attack

Jin Kang is a highly skilled hacker whose career takes a disastrous turn after he falls into a broker’s carefully laid trap. The resulting mission failure nearly costs him his life, and though he manages to escape, the psychological toll proves too heavy to bear. Unable to face VX—a brilliant hacker and teammate he deeply admires—Jin Kang retreats from his former world entirely, choosing instead to vanish into anonymity. To maintain his cover, he adopts a quiet double life. By day, he works behind the counter of a modest café, blending in with the mundane routine of ordinary society. By night, he operates in the shadows, meticulously orchestrating a plan for revenge against those who ruined him. This fragile balance seems sustainable until an unexpected disruption shatters his carefully constructed isolation. A striking and enigmatic customer named Seo Yi-Yeon walks into the café and immediately begins making bold, forward advances toward him. Jin Kang is left completely bewildered by her sudden and intense interest. As Yi-Yeon inserts herself into his hidden life, the meticulous plans he has spent months cultivating begin to unravel, forcing him to confront complications he never anticipated.
