Triple board specialist Kim Yun and Haeseong Medical Center, Seoul's premier tertiary general hospital.

Haeseong Medical Center
Located in Seoul, Haeseong Medical Center is a massive tertiary general hospital and a top-tier domestic medical institution equipped with systems for high-difficulty surgery, critical care, multidisciplinary collaboration, and emergency/trauma response. An independently operated hospital with 2,300 beds, it operates 24/7, centered around its massive main building, emergency center, Regional Trauma Center, ICUs, central surgical center, outpatient center, research buildings, and educational facilities.
This is not just a large-scale hospital. The standards of major surgical departments, including General Surgery, Thoracic Surgery, and Neurosurgery, are exceptionally high, making it a hub for high-risk patients and complex surgical cases transferred from all over the country. In the ER, split-second decisions are made constantly, while in the wards and ICUs, changes that determine life and death post-surgery are continuously monitored. In consultation rooms, specialists from various departments gather to coordinate treatment directions, and in operating rooms, skilled medical staff move with precise teamwork.
Within Haeseong Medical Center, everything from outpatient care, rounds, and surgeries to emergency response, consultations, research, briefings, and administrative reporting moves quickly and accurately. Among the medical staff, strong trust, tension, responsibility, and competition exist together, and one person's judgment can significantly change a patient's prognosis and the hospital's atmosphere. A space where cold professionalism, heavy authority, and the desperation to save lives flow simultaneously. Haeseong Medical Center is a massive medical frontline operating with the most intensity and precision in the heart of Seoul.

Thursday, January 1, 2026, 7:00 AM.
A winter morning in Seoul is quietly submerged under a cloudy sky and thin flurries of snow.
The scenery outside the window is hazy, while the bedroom is warm and silent. In the tidy room, only a phone, a water glass, and a hair tie are placed neatly. There is no unnecessary clutter; it is a lived-in space, but not a messy one.
This bedroom looks like a space naturally maintained by someone accustomed to self-control, rather than a space meant for display.
You are sitting quietly on the bed, having just woken up. You are dressed comfortably in a cardigan over thin silk pajamas. Your mind isn't fully clear yet, but your physical condition is stable and you feel no deep fatigue. Your expression is calm and indifferent.
Only the slight daze unique to someone who has just emerged from sleep remains; no pain or heavy exhaustion is felt. The quiet air filling the bedroom and the snow falling outside have not yet pushed her out into the daily grind.
Inside the hospital, you are the Director of the High-Difficulty Surgery Center at Haeseong Medical Center, a figure who makes calmer, colder, and more accurate judgments than anyone else.
In the operating rooms and wards, you command the atmosphere with brief, precise words, existing as a presence that inspires absolute trust and tension among residents, fellows, nurses, and fellow doctors alike.
But for this moment, it is simply a morning without operating rooms, wards, or rounds. There is no specific partner or spouse, and all relationships remain as possibilities to be formed in the future.
You hope today starts normally, but a quiet tension that is hard to explain remains in a corner of your heart. The phone screen is still dark, and no one has called for you yet.
The morning of New Year's Day has opened quietly, and how to start this day still depends solely on Kim Yun's choice.
It's your turn.
