Chapter 1: the diagnosis

Chapter Text

The fluorescent lights in the Gangneung Public Clinic buzzed like dying insects, casting a sickly yellow pallor over the cracked linoleum floors. Salt air from the East Sea seeped through the ill-fitting windows, mixing with the sharp tang of antiseptic and the faint, underlying rot of damp that never quite dried out in this old building. Jungkook sat on a plastic chair that wobbled under his weight, his arms wrapped tight around Jimin, who had finally dozed off against his chest after another round of blood draws. The toddler’s small body felt too warm, his breathing shallow and uneven, little puffs that tickled the side of Jungkook’s neck.

Jungkook’s back ached from the hard seat, but he didn’t dare move. Jimin had been fussy all morning, his usual bright giggles replaced by whimpers and that terrifying pallor that made his cheeks look almost translucent. At two years and eight months, Jimin should have been running everywhere, demanding to be swung high or chasing the gulls down by the fishing docks. Instead, he tired after just a few steps, bruises blooming too easily on his soft skin.

The doctor’s voice, when it finally came, was quiet. Too quiet. Dr. Park, an older beta woman with tired eyes and a white coat that had seen better days, closed the file on her desk and leaned forward.

“Mr. Jeon… the results confirm severe aplastic anemia. Jimin’s bone marrow isn’t producing enough blood cells. It’s failing. We’ve ruled out the more common environmental triggers, but without intervention—”

Jungkook’s ears rang. The words blurred together—transfusions, immunosuppressants, stem cell transplant. The best outcomes came from a full sibling donor. A matched sibling. Natural conception offered the highest compatibility rates, especially in cases like this. Dr. Park’s mouth kept moving, but Jungkook could only hear the crash of waves in his memory, the way the East Sea used to roar against the cliffs during their stolen nights.

He nodded mechanically, signing papers he barely read. His hands shook so badly the pen slipped twice. When the doctor left to arrange the next round of tests, Jungkook slid from the chair onto the cold floor, right there in the cramped exam room. The linoleum pressed against his knees, unforgiving and sticky. Jimin stirred but settled again, his small fist curling into Jungkook’s thin hoodie, right over the spot where his heart hammered like it wanted to escape.

Tears came hot and silent at first, then broke into ragged sobs that he tried to muffle against Jimin’s soft hair. The boy smelled like baby powder and that faint, sweet milky scent all omegas recognized in their own pups, laced now with the metallic edge of illness. “I’m sorry,” Jungkook whispered, voice cracking. “Baby, I’m so sorry. Appa’s got you. I’ll fix this. I swear I’ll fix it.”

The clinic walls felt like they were closing in, the distant hum of fishing boats from the harbor outside a cruel reminder of the life he’d scraped together here. This wasn’t supposed to happen. Not after everything.

 

Two and a half years ago, the world had smelled different. Pine forests heavy with rain, the sharp brine of the sea, and Taehyung—always Taehyung—his alpha scent like warm sandalwood and ocean storm, wrapping around Jungkook like a promise.

They’d met during a resort launch event. Jungkook, still riding the tail end of his backup dancer career, had been hired for the entertainment at Vante Haven’s flagship property just outside Gangneung. Taehyung had been everywhere that night: commanding the room in a tailored black suit, voice low and smooth as he charmed investors, but his eyes kept finding Jungkook across the candlelit terrace. Later, under the cliffs where the private beach curved into darkness, Taehyung had pressed him against smooth rock and kissed him like the world was ending. “You’re trouble, little omega,” he’d growled, teeth grazing Jungkook’s scent gland. “The best kind.”

Months blurred into something fierce and alive. Secret weekends at the half-finished resorts, Taehyung teaching him to sketch the ocean views while Jungkook taught him messy tattoo designs on paper. Nights where heat and rut crashed together like the East Sea in typhoon season—raw, possessive, tender in the aftermath when Taehyung would trace the ink on Jungkook’s skin and whisper about futures neither of them had planned yet.

Then the scandal hit. Tabloids screaming gold-digger, fame-hungry omega latching onto the Kim shipping heir turned resort king. Taehyung’s family had pulled strings, planted the stories. Jungkook remembered the night it all shattered with brutal clarity. He’d shown up at Taehyung’s Seoul penthouse, heart in his throat, positive test hidden in his pocket like a secret he couldn’t wait to share.

Taehyung had been exhausted, eyes shadowed from weeks of negotiations. The papers were already spread across his desk. “Was any of it real?” he’d asked, voice like ice. “Or were you just waiting for the right moment to cash in?”

Jungkook had tried to explain, but the words wouldn’t come fast enough. Taehyung’s final ones still echoed: “Get out. Don’t ever come back. I don’t want to see your face again. You’re nothing but a mistake.”

The door had slammed. Jungkook had walked the streets until dawn, then taken the first train back to Gangneung, where no one knew him. He’d hidden the pregnancy, worked odd jobs, tattooed tourists when his body allowed, danced in small local performances until the baby bump made it impossible. The tiny rented room above the seafood restaurant became their world—leaking roof, mold on the walls, the constant smell of fish and salt. But Jimin had been worth it. Every feverish night, every sacrifice.

Until now.

Jungkook rocked gently on the clinic floor, humming a broken lullaby under his breath. Jimin’s weight was both anchor and heartbreak. A sibling. Another baby. The words circled in his head like gulls. He couldn’t even think about how, or with whom. Not after Taehyung. Not after the way that alpha had looked at him like he was dirt.

 

Miles away, perched on the dramatic cliffs north of Gangneung, Vante Haven’s private estate stood like a sentinel against the East Sea. Modern hanok lines blended with floor-to-ceiling glass, pine trees whispering around the perimeter, the crash of waves a constant soundtrack far below. Kim Taehyung’s office overlooked the horizon, the massive oak desk cluttered with resort blueprints and untouched coffee.

His assistant had brought the package in without comment—an unmarked brown envelope, delivered by courier. Taehyung sliced it open with a silver letter opener, expecting contract revisions.

Photographs spilled out first. A toddler with familiar dark eyes and a stubborn cowlick. The boy laughing in a threadbare onesie, the same boy looking pale and hooked to machines. Medical files. Blood types. Paternity results stamped with cold finality: 99.98% match to Kim Taehyung.

A single note in plain print: He’s yours. Both of them need you.

The world tilted. Taehyung stood slowly, the chair scraping back. His hands trembled—not from weakness, but from the volcanic rage building in his chest. “Jungkook,” he breathed, the name tasting like blood and salt.

The first crash came as he swept the desk clear. Blueprints fluttered like dying birds. The coffee mug shattered against the wall, dark liquid streaking the pale wood paneling. He grabbed the heavy brass lamp and hurled it into the glass display case holding miniature models of his resorts. Glass exploded. Frames with awards and magazine covers— “Self-Made Visionary,” “King of Eco-Luxury”—hit the floor, cracking.

Taehyung’s roar echoed through the empty wing of the villa. He tore at the photographs, then stopped, staring at the boy’s face. His son. A son he’d never known existed, living in some rundown hole while Jungkook—his Jungkook—had hidden him.

The alpha’s scent flared wild and dark, pine and storm crashing through the room, overpowering even the sea air drifting through the open terrace doors. He sank into the ruined chaos of his study, chest heaving, fists clenched around the paternity papers until they crumpled like his control.

Outside, waves hammered the cliffs below, relentless and unforgiving. Inside, Kim Taehyung sat among the destruction, eyes burning with fury and something far more dangerous—something that felt like the first cracks in two and a half years of ice.

Jungkook had no idea the storm was already coming for them.
