2. 地下交易

The flight to Busan took ninety minutes. Keisuke spent every one of them staring at the back of the seat in front of him, his mind turning over the same questions like stones in a river, searching for some smooth surface of reassurance that never emerged. The man beside him, a middle-aged Korean businessman with a watch that probably cost more than Keisuke's entire wardrobe, had offered him a mint. Keisuke had refused. He was fasting, as the letter had instructed. Nothing but water since midnight.

The plane touched down at Gimhae International Airport at eleven in the morning. The sky was a pale, washed-out blue, the humidity wrapping around Keisuke like a damp blanket as he walked through the jet bridge. He had never left Japan before. His passport was brand new, issued three weeks ago at an office in Nagasaki, the photograph already looking like a stranger. He carried nothing but a small duffel bag and the leather folder, which he had not been able to let out of his sight since the night it arrived.

A driver was waiting for him in the arrivals hall. She was a young woman in a crisp white blouse, holding a tablet with his name displayed in neat kanji characters: MINATO KEISUKE. She smiled when she saw him, a professional smile that revealed nothing.

Welcome to Busan, Minato-san, she said in flawless Japanese. My name is Park Mi-yeon. I will be your liaison during your stay at the Institute. Please follow me.

She led him to a black sedan identical to the one he had seen outside the KLS Holdings building in Nishizaki. The interior smelled of leather and something floral, a scent that reminded Keisuke of funeral parlors. He pushed the thought away.

How long have you worked for the Institute? he asked, more to break the silence than out of genuine curiosity.

Three years, she said. Her eyes met his in the rearview mirror, dark and unreadable. I was a nurse at Seoul National University Hospital before this. The Institute recruited me for my language skills. We receive many clients from Japan.

Clients, Keisuke repeated. Not patients. Not donors. Clients.

The word hung in the air between them, and neither spoke again for the remainder of the drive.

Haeundae Regenerative Medicine Institute was not what Keisuke had imagined. He had pictured something clinical, sterile, hidden away in an industrial district or behind high concrete walls. Instead, the sedan pulled up to a glass-and-steel tower that rose twenty stories above the coastline, its windows reflecting the glittering expanse of the East Sea. A marble fountain bubbled in the circular driveway. Palm trees lined the entrance. It looked like a luxury hotel, or perhaps a corporate headquarters for a company that had more money than it knew what to do with.

The lobby was even more impressive. A chandelier of cascading crystal hung from the ceiling, throwing prismatic light across floors of polished white stone. Behind the reception desk, a wall of living greenery spelled out the Institute's initials in moss and ferns: HRMI. The air smelled of jasmine and something antiseptic beneath it, that same hospital smell Keisuke remembered from Takeda's office.

We have you in a private suite on the fourteenth floor, Mi-yeon said, handing him a keycard. The surgery is scheduled for the day after tomorrow. Today and tomorrow will be dedicated to pre-operative testing and consultation. Dr. Yoon will meet with you this afternoon.

She paused, her hand resting briefly on his arm. Her touch was cool, impersonal, but there was something in her expression that Keisuke could not quite read. Concern, perhaps. Or warning.

Is something wrong? he asked.

No, she said, too quickly. Nothing is wrong. I only wanted to say that you should read everything carefully before you sign. All the documents. Every page.

Before he could ask what she meant, she had turned away and was walking toward the elevators, her heels clicking against the stone floor in a rhythm that reminded him of the woman in Nishizaki, the one in the charcoal suit, the one who had opened the door and changed everything.

His suite was larger than his apartment. The windows faced the sea, and the afternoon light poured through them in sheets of gold. There was a king-sized bed with white linens, a marble bathroom with a rainfall shower, a minibar stocked with sparkling water and fresh fruit. A welcome basket sat on the desk, filled with Korean snacks and a handwritten note welcoming him to the Institute. The note was signed by someone called Dr. Yoon Jae-hyun, Medical Director.

Keisuke stood at the window for a long time, watching the waves fold against the shore. Somewhere below him, in another room of this building, Takeda Shinjiro was also waiting. He had not seen the man since that night in Nishizaki, but he could feel his presence like a pressure in the air, a gravitational pull that had drawn him across the sea to this place.

At three o'clock, a nurse came to escort him to the pre-operative consultation. She was young and cheerful, with a name tag that read KIM SO-YOUNG. She chatted about the weather as they rode the elevator to the eighth floor, about the beaches and the seafood and the beauty of Busan in spring. Keisuke nodded along, letting her words wash over him without really hearing them. He was thinking about Mi-yeon's warning. Read everything carefully before you sign.

The eighth floor was a medical wing. The walls were white, the lighting fluorescent, the atmosphere suddenly and jarringly clinical after the luxury of the lobby and the suites. A series of examination rooms lined the corridor, their doors closed, their windows frosted. From behind one of them, Keisuke could hear the low murmur of voices. From behind another, silence.

Dr. Yoon's office was at the end of the hall. He was a man in his late fifties, with silver hair and the calm, measured hands of someone who had spent decades inside operating rooms. His Japanese was accented but fluent, learned during a fellowship in Osaka many years ago, he explained as he gestured for Keisuke to sit.

You are in excellent health, Minato-san, he said, reviewing a file that Keisuke assumed contained the results of the blood tests and tissue typing that had been done without his knowledge, perhaps months ago, perhaps longer. Your kidney function is optimal. Your cardiovascular health is excellent. There is no reason to expect any complications from the procedure.

What about afterward? Keisuke asked. After I only have one kidney.

Dr. Yoon set down the file. His expression was patient, practiced, the expression of a man who had delivered this same reassurance many times before. You can live a perfectly normal life with one kidney. Many people do, whether by donation or by birth. There are some lifestyle adjustments, of course. You will need to monitor your blood pressure, avoid certain medications, maintain a healthy diet. But nothing that would significantly impact your quality of life.

And if something goes wrong?

The risk of serious complications from a laparoscopic nephrectomy is less than one percent. Dr. Yoon folded his hands on the desk. But I would be remiss if I did not tell you that any surgery carries risks. Infection. Adverse reaction to anesthesia. Unexpected bleeding. These are possibilities, however remote. You will be asked to sign documents acknowledging these risks before we proceed.

Documents. Keisuke thought of the leather folder, the thirty-page agreement, the list of names at the back. All donors are alive and in good health at time of publication.

May I see the full consent forms? he asked. Before the surgery. I want to read them tonight.

Dr. Yoon hesitated. It was a small hesitation, barely a flicker, but Keisuke caught it. Of course, the doctor said. I will have them sent to your room this evening.

That night, Keisuke sat in his suite with the consent forms spread across the bed. There were forty-seven pages in total, filled with legal language so dense he had to read each paragraph twice to extract its meaning. The documents described the surgical procedure in exhaustive detail. They outlined the risks, the recovery timeline, the long-term health implications. They specified the compensation in precise terms: thirty million yen, plus an additional five million for ancillary expenses, exactly as Takeda had promised.

But there was something else. On page thirty-two, buried in a subsection labeled Supplemental Medical Procedures, was a clause that made his blood run cold.

The Donor hereby consents to the collection and preservation of additional biological materials, including but not limited to blood plasma, bone marrow, and hepatic tissue samples, for the purpose of ongoing medical research and potential future therapeutic applications. Such collection may occur during the primary surgical procedure or during subsequent procedures as deemed medically necessary by the attending physician.

Hepatic tissue. Liver. Bone marrow. They were not just taking his kidney. They were reserving the right to take more.

Keisuke read the clause again, then a third time. The language was vague enough to be almost meaningless, and yet specific enough to be terrifying. Potential future therapeutic applications. Subsequent procedures. The words swam before his eyes, blending together into a single, sickening implication: he was not a donor. He was a resource. A renewable one.

He thought about calling Mi-yeon. She had told him to read everything carefully. She had known, or at least suspected, what was buried in these pages. But her warning had come with no explanation, no context. Why would an employee of the Institute be trying to help him? What did she know that she was not telling him?

He did not sleep that night. He sat in the chair by the window, watching the moon track across the sea, and tried to convince himself that he was overreacting. The clause was standard, probably. A legal formality. The Institute was a research facility as well as a surgical center. Of course they would want to collect samples. Of course they would ask permission. It did not mean they intended to harvest him piece by piece.

But he could not stop thinking about the list of names in Takeda's folder. Dozens of names. Dozens of donors. All alive and in good health. At time of publication.

Publication. Such an odd word to use. As if the list were a catalog, a menu, an inventory of available parts.

The next morning, he went looking for answers.

The Institute was larger than it seemed, sprawling through a complex of interconnected buildings that stretched down to the shoreline. Keisuke wandered through corridors and lobbies, past research labs and recovery wards, through gardens where patients in white robes sat on benches and watched the waves. No one stopped him. His keycard opened most of the doors he tried. He was a client, after all. A guest. A valuable asset.

He found the records room on the fifth floor of the east wing. The door was unmarked, tucked between a supply closet and a stairwell, but it was unlocked. Inside, filing cabinets lined the walls from floor to ceiling, each drawer labeled with a year and a series of codes that Keisuke could not decipher.

He started with the most recent drawer. The files were alphabetized by donor surname, each one containing a photograph, a medical history, and a signed consent form identical to the one in his suite. He flipped through them quickly, his heart hammering against his ribs. Most of the donors were young, like him. Most were from Japan, Korea, China, the Philippines. Most had been compensated in amounts that ranged from twenty to fifty million won, or the equivalent in their local currencies.

Then he found a file that stopped him cold.

The photograph was of a man in his early twenties, handsome, with a smile that seemed genuine. His name was Tanaka Ryota. He had been a donor two years ago, at the age of twenty-four. His file was thick, much thicker than the others, stuffed with medical reports and surgical notes. Keisuke scanned the pages, his Japanese picking out fragments of clinical language.

Donor Tanaka experienced complications during the primary nephrectomy. Excessive blood loss. Emergency intervention required. Recovery prolonged. Donor Tanaka consented to a secondary procedure for hepatic tissue collection four months post-primary. Donor Tanaka consented to a tertiary procedure for bone marrow extraction seven months post-primary. Donor Tanaka was transferred to the long-term care facility in—

The last page was a death certificate. Cause of death: multiple organ failure. Date: eighteen months after his initial donation.

Keisuke's hands were shaking so badly he could barely hold the file. He turned to the last document, a memo typed on Institute letterhead, addressed to someone whose name had been blacked out with heavy marker. The subject line read: Subject Viability Assessment. The body of the memo was brief.

Subject Tanaka has been deemed non-viable for further procedures. Remaining assets have been liquidated in accordance with Protocol 7-B. Family was notified of subject's passing due to natural causes. No inquiries are anticipated.

Liquidated. The word was obscene in its clinical detachment. Tanaka Ryota had not died of natural causes. He had been used up, piece by piece, until there was nothing left worth taking. And his family had been told a lie.

Keisuke heard footsteps in the corridor. He shoved the file back into the drawer and slipped out of the room, his heart pounding so loudly he was certain it would give him away. He walked quickly, not running, keeping his face blank, his stride measured. A nurse passed him in the hallway and smiled. He smiled back, his lips stretching into a shape that felt like a wound.

Back in his suite, he locked the door and slid to the floor, his back against the wall. He was breathing too fast, his vision swimming at the edges. He thought about the plane ticket in his duffel bag. He thought about the thirty million yen. He thought about Tanaka Ryota, who had been twenty-four years old and healthy and alive until the Institute had decided he was worth more in parts than as a person.

He had to get out. He had to leave this place, tonight, before they took him into surgery and discovered that one kidney was only the beginning. He would go back to Japan. He would find a way to pay his debts. He would—

A knock at the door.

Minato-san? It was Mi-yeon's voice, soft and urgent. May I come in? It's important.

He opened the door. She slipped inside, her face pale, her composure cracked. In her hand was a tablet, its screen glowing with a document he could not read.

You went to the records room, she said. It was not a question. The security system flagged your keycard. They know you were there.

I didn't—

Listen to me. She grabbed his arm, her grip surprisingly strong. You are not the first person to discover what this place really is. But you are the first one who might have a chance to do something about it. There is a man here, a donor like you. His name is Chen. Chen Wei-lin. He arrived two weeks ago, and they have already taken a kidney and a lobe of his liver. Tomorrow they want his bone marrow. He has been trying to escape. They have him in a secure ward on the thirteenth floor.

Why are you telling me this? Keisuke asked. Why are you helping me?

Mi-yeon's eyes met his, and for the first time he saw something raw there, something that had been buried beneath the professional smile and the crisp white blouse. Because I helped bring him here, she said. Because I have brought dozens of people here, and I told myself it was ethical, that they were making choices, that the money was enough. And then I saw what happened to the ones who stayed too long. The ones who became non-viable.

What do you want me to do?

I want you to help me get Chen out. There is a supply shipment leaving at midnight, a truck that goes to the port. If we can get Chen onto that truck, he can make it to the Japanese consulate. He has evidence, documents he managed to photograph before they moved him to the secure ward. Evidence of what the Institute is really doing. Evidence of who is behind it.

Who? Keisuke asked, though he already knew the answer.

Takeda Shinjiro is not just a client, Mi-yeon said. He is the founder. The majority shareholder. The Institute exists because he created it, six years ago, when he was first diagnosed with renal failure. He needed a reliable supply of compatible organs, and he had the money to build an entire infrastructure around that need. Every donor, every surgery, every death, it all traces back to him.

Keisuke thought about the dying man with the burning eyes, the oxygen tube looped behind his ears, the machine humming behind his chair. He thought about the smile that was not a smile, the voice that spoke of paths we were always meant to walk. He thought about the word non-viable and the death certificate of Tanaka Ryota and the memo that spoke of liquidation.

Where is Takeda now? he asked.

Here, Mi-yeon said. He arrived this morning. The surgery is scheduled for tomorrow at noon. He will receive your kidney, and then he will go back to Japan, and this place will continue, and Chen will become another file in the records room. Unless we act tonight.

The suite was very quiet. Beyond the window, the sea continued its eternal rhythm, indifferent to the choices being made on its shores. Keisuke looked at his hands and saw that they had stopped shaking. Somewhere inside him, fear had calcified into something harder. Something that felt almost like resolve.

Tell me what to do, he said.
