Undercover (Gagim)

Han Si-jun, an undercover agent for the National Intelligence Service, takes on the role of a priest at the Russian St. Sergius Cathedral. There, he encounters Anna, a Korean orphan, and their relationship sparks the beginnings of his first love. But every time Si-jun meets her gaze, a lingering unease stirs within him, slowly unlocking memories he thought were long buried. As his feelings for Anna deepen, the true purpose of his mission comes to light—stopping the Russian mafia’s illegal arms trade. To protect Anna and complete his mission, Si-jun must confront the shadows of his past.
