Son Naeun to Play Surveillance Role for So Ji Sub

The true identity of Jung Sang-a (played by Son Na-eun), who appeared as an MZ trendsetter in the SBS Friday-Saturday drama 'Chief Kim', has been revealed. Jung Sang-a, who was known as Chief Kim's (played by So Ji-sub) colleague, was actually an agent from the Special Mission Bureau.

In the episodes aired on the 3rd and 4th, Chief Kim was shown making efforts to find his missing daughter, Kim Min-ji (played by Seo Su-min). With the help of Sung Han-soo (played by Choi Dae-hoon) and Park Jin-chul (played by Yoon Kyung-ho), Chief Kim tracked down clues about his daughter's whereabouts.

When Chief Kim's identity was exposed, the Special Mission Bureau intervened. Jung Sang-a went to find Chief Kim herself, as he had not appeared at the company. Although she was known as an ordinary bank employee, she was an agent tasked with monitoring the retired Chief Kim.

Jung Sang-a visited the school attended by Chief Kim's daughter, Min-ji, and determined that Chief Kim's actions were related to his daughter. Afterward, she confronted Chief Kim and showcased full-fledged action acting in the process of confronting him to stop his rampage.

Son Na-eun masterfully handled high-level action sequences using guns and knives, and heightened anticipation by revealing her transformed identity with a different gaze and demeanor than before. Attention is focused on Son Na-eun's performance, which delivered a dramatic twist along with the reveal of her true identity.
