Park Byung-eun

Park Byung-eun (박병은) spent years building the kind of filmography that directors trust when they need quiet force instead of empty noise. After grinding through smaller roles, he broke through harder with Assassination, widened his television reach with Kingdom and Eve, and kept proving he could add menace or fatigue without flattening a character. In 2026 he joins The Completion of Marriage as former violent-crimes detective Lee Soo-hyung, a role that fits the tension-heavy lane KBS2 is pursuing with support from KBS Media and Red Nine Pictures. With KBS treating the series like a weekend-slot reset, Park's presence helps give the ensemble real weight instead of surface prestige.
