Prologue: 7 Minutes of Wandering, and a Hidden World Uncovered

“It took only 7 minutes for a single MRI scan to change a person’s life.”

At 11:45 PM in a university neighborhood in Seoul. Thrown onto the cold asphalt floor of a dark alley, 22-year-old Ji-woo Seo (a pseudonym) had no idea that two strange universes—two worlds that should never have met—were coexisting inside her body.

A youth who spent her days rushing across campus carrying a backpack stuffed with heavy textbooks and notes, worrying about academics and scholarships, and her nights gripping the handlebars of a scooter for a part-time chicken delivery job to make ends meet. Ji-woo’s world was fierce yet simple. She brushed off the occasional dull ache in her back as the result of overwork and study stress from sitting too long in the library, and she dismissed her frequent bouts of catching colds every winter as a simple inheritance of chronic rhinitis.

“This level of fatigue is just a badge of honor that every college student wears.”

Ji-woo had comforted herself with those thoughts and pushed through each day. However, the pendulum of fate was already stepping up to extreme acceleration. At a late-night alley intersection where a delivery rider’s instincts had grown dull, she suddenly twisted her handlebars to avoid an unlicensed motorcycle darting out with glaring headlights—the scooter slipped on the wet pavement, and Ji-woo was hurled off, striking her right ribcage heavily against the concrete curb.

Entering the Emergency Room Under Glaring White Lights

Accompanied by a tearing, dull pain and sudden breathing difficulty, amid the wailing siren of an ambulance, Ji-woo was rushed into the university hospital's emergency stretcher bay. The stark white lights of the emergency center were piercingly blinding, and according to trauma protocols, a rapid whole-body trauma CT scan was immediately ordered to stabilize her vital signs.

Standing in front of the large monitor in the emergency duty room, Professor Elias Lee of the Department of Radiology opened the latest digital images with a light heart. Washing away the fatigue of a night shift with a warm sip of coffee, he quickly scanned for typical trauma signs commonly found in fall-accident patients, such as rib fractures, liver lacerations, or splenic ruptures.

A moment later, a young resident caught his breath and reported:

“Professor, aside from a suspected micro-fracture of the rib, no specific traumatic lesions are observed. There is no evidence of intra-abdominal bleeding either.”

Stopping at the Boundary of the Diaphragm

Hearing the resident's report with a sense of relief, Elias slowly—and out of the long-honed instinct of a radiologist to verify the overall anatomical structure even in trauma cases—scrolled his mouse further down. However, when he reached the boundary line between the lower thorax and the abdomen, the exact zone where the diaphragm should reside, his fingers gripping the mouse wheel froze like stone.

The cross-sections on the monitor were not the map of a standard human body. It was a massive shock, akin to encountering an unknown ancient labyrinth sealed away for hundreds of years.

The moment he withdrew his sharp gaze searching for traumatic lesions and looked back at the entire scan through the mirror of human embryology and anatomy—the startling secrets that had silently sustained Ji-woo’s 22 years of life quietly emerged in overwhelming reality. It was no longer a routine emergency check for bruises. The grand epic of the most intricate and bizarre congenital anomaly the human body could possibly harbor was finally turning its very first page.

Part I: The Genesis of Disease – Subtle Fissures within a Peaceful Life

To Ji-woo, the accident that night was a bolt from the blue, but looking back, it was an urgent distress signal that her body had been sending incessantly for years, one that everyone failed to heed.

Whenever the threshold of winter arrived, a stubborn cold would lodge deep inside her lungs, refusing to go away, forcing her to frequent neighborhood corner ENT clinics. She experienced chronic shortness of breath where her chest would grow tight, and her breath would catch in her throat even after walking just a block or two further than others. And occasionally, when she tried to focus on her studies, a dull, piercing pain like an awl would stab through the pit of her stomach and her left upper back. Ji-woo blamed these symptoms entirely on caffeine overload from surviving on vending machine coffee and energy drinks, alongside the overwork and lack of exercise brought on by her grueling college life.

“I’m twenty-two years old. This level of fatigue and stiffness is just a natural tax you pay for being young.”

Balancing her time as a campus work-study student at the university library striving to keep her scholarship during the day, and mechanical chores combined with chicken delivery part-time jobs at night to pay for tuition and rent, fatigue was simply a constant in Ji-woo’s life.

Ji-woo’s parents, operating a worn-out soup restaurant in a small provincial town in Chungcheong Province, were perpetually consumed by guilt for sending their youngest daughter off to Seoul alone. Whenever Ji-woo would let her voice trail off during a phone call, saying, “Mom, I’m a little tired these days because of deadlines,” her father would wipe red eyes in front of the boiling cauldron and offer nothing more than clumsy comfort: “Make sure to eat chicken soup properly; I’ll wire some pocket money to your account.”

Sitting hunched over on a gray plastic chair in the emergency room corridor, Ji-woo’s mother recalled how Ji-woo had casually dropped a remark when she visited home during the Lunar New Year holiday a few months ago: “Mom, whenever I breathe, sometimes the inside of my left ribcage tingles and feels sore.” At the time, her mother had dismissively handed her a bottle of Bacchus energy drink, saying, “You probably got neuralgia from sleeping on the cold floor to save on rent.” That careless passage of time now felt like a knife slashing through the mother’s chest. The rhythmic “beep— beep—” sound of the vital sign monitor visible through the emergency room’s glass door felt like a relentless countdown of unspooling, unyielding tears.

The Radiologist's Instinct Beneath the Emergency White Lights

The interior of the hospital emergency room remained a battleground past midnight. Amid the tangled wails of patients brought in by ambulances and the urgent walkie-talkie chatter of residents, Assistant Resident Han Young-jun of the Department of Surgery, who had completed the initial trauma screening, knocked on the reading room door with a tense expression.

“Professor, here are the initial CT scan results following the emergency trauma protocol. Fortunately, there is no evidence of intra-abdominal solid organ rupture or clear rib fracture lines. Vital signs have also stabilized.”

It was a report that they had overcome the worst acute hurdles of traumatic hemorrhage or fracture. However, Professor Elias Lee of the Department of Radiology could not easily pull his hand away from the mouse even after hearing the resident's words. His gaze was firmly fixed on the initial low-dose Scout View image floating at the top of the monitor.

 “Han, it’s too early to relax just because there are no trauma findings. Look closely at the left diaphragmatic line on this scout view again. The shadow in the lower thorax is completely different from ordinary emphysema or simple pleurisy.”

When Elias abruptly switched the Multi-Planar Reconstruction (MPR) screen from the axial plane to the coronal plane, the air inside the emergency reading room instantly grew as cold as if it had frozen over.

On the night of the accident, under the cold white lights of the emergency room, Ji-woo was suppressing the pain around her ribs and panting heavily. She remained utterly terrified, completely unaware that for 22 years, her body had been harboring an embryological secret so wondrous and perilous that it threatened to rewrite modern medical textbooks.

A mere 7 minutes of a scooter fall accident. That minor collision had ruthlessly shattered Ji-woo’s peaceful college life, but paradoxically, through that fractured fissure—a massive medical mystery that had slumbered hidden beneath the surface for decades, waiting to erupt- was now raising its head.
