Jang Seung-jo shows fighting spirit in emergency surgery in episode 4 of 'Doctor X'... achieves a new high of 20.8%

Jang Seung-jo made a strong impression by appearing as surgical professor Na Dae-il in SBS’s Friday-Saturday drama ″Doctor X: The Era of the White Mafia.″ In episode 4, which aired on the 17th, Na Dae-il was introduced as a newly appointed surgical professor at Guseodae Hospital. From his first appearance during a surgery scene with Kye Soo-jung (played by Kim Ji-won), he showed exceptional skill and speed, sparking curiosity. He watched Kye Soo-jung’s surgery videos and approached her with his characteristic gentle attitude and relaxed smile, creating a subtle tension between them. Later, with the arrival of pharmaceutical company employee Kwon Chung-hyun, who was rushed to the emergency room with cholecystitis, Na Dae-il’s past was revealed. During his long service as a military medical officer, Na Dae-il judged that there was no time to transfer Kwon Chung-hyun, who had suffered severe internal bleeding from harsh treatment, to a military hospital. He went alone to a rural clinic, risking danger to perform surgery. Back in the present, as Kwon Chung-hyun’s condition rapidly worsened and Kye Soo-jung began emergency open surgery, cracks appeared on Na Dae-il’s usually composed face. Unable to hide his anxiety and anger at the mention of open surgery, he rushed into the operating room amid tension. The episode ended with Kye Soo-jung discovering a ″D.N″ mark on Kwon Chung-hyun’s liver, hinting at Na Dae-il’s initials. Jang Seung-jo delicately portrayed Na Dae-il’s complex character, from his gentle first impression to subtly trembling eyes and unexpected outbursts of anger. Episode 4 recorded the highest ratings for the series, with a peak of 20.8% nationwide, 18.5% across the country, and 18.4% in the metropolitan area according to Nielsen Korea. It ranked first in its time slot, on Saturdays, and among weekly mini-series overall. SBS’s Friday-Saturday drama ″Doctor X: The Era of the White Mafia″ airs every Friday and Saturday at 9:50 PM.
