Overall Story
Choi Ban‑seok (Jung Jae‑young), a veteran engineer at Hanmyung Electronics, faces his worst nightmare when corporate downsizing forces him out of his comfort zone and into the HR department. For Ban‑seok, who spent over two decades building products, being reassigned to bureaucracy feels like a death sentence.
