The news report describes a 뺑소니 (ppaeng-so-ni) — a hit-and-run accident — where the ambulance was turned away by five hospitals before the patient died en route. This opening mirrors a real public debate in South Korea: the country has long lacked enough Level-I trauma centres (중증외상센터), and patients in critical condition sometimes 'hospital-shop' by ambulance because no single facility will accept them.
Colleagues mention that Baek Kang-hyeok spent about six years with what sounds like a humanitarian medical organisation — the drama's version of groups like Médecins Sans Frontières. Working in conflict zones such as Syria means dealing with mass-casualty blast injuries and gunshot wounds daily, giving a surgeon more critical trauma experience in a year than many Korean hospital doctors see in a decade.
Baek mutters that the emergency operating room was built 면피용 (myeon-pi-yong) — 'for avoiding blame.' In Korean institutional culture, this means a facility created just to satisfy a government checklist or deflect criticism, with no real intention of running it properly. The fact that the room has barely been used confirms his suspicion that the hospital took the ministry grant but never committed to actual trauma care.
Baek's provocative declaration that he came to 셔터 내리다 (shut down / pull down the shutter) borrows the image of a small shop closing for good. In context he means he intends to dismantle the token, half-hearted trauma team — then immediately pivots to reveal he actually wants to rebuild it as a fully accredited 중증외상센터 (trauma centre). The bait-and-switch stuns the room.
The rescue team leader mentions a 공문 (official government directive) that came down a year ago allowing doctors to fly with the 중앙구조단 (Jungang Gujodan — National 119 Rescue Service) helicopters. This reflects South Korea's gradual roll-out of physician-staffed HEMS, where a trauma doctor treats the patient at the scene or in-flight rather than waiting at the hospital — a model still being expanded at the time the show is set.
