AFTER THE DIVORCE, I BECAME A BILLIONAIRE

CHAPTER 4: YOON SEO-RIN

Three weeks before Kang Tae-jun learned his father’s name, Yoon Seo-rin sat at the far end of a mahogany conference table and watched seven people lie to one another.

The meeting was held in a private suite above an upscale traditional restaurant in Samcheong-dong—a place that officially did not exist on any municipal map. There were no corporate logos etched into the frosted glass, no security cameras recording the hallways, and no waitstaff permitted to remain in the room long enough to remember a face.

The Cheonghwa Council preferred its solitude absolute.

Seo-rin sat motionless, a heavy leather audit binder open before her. Her white silk blouse was pristine, her posture perfect—the picture of an icy, unbothered internal corporate auditor.

"You're telling us there is no discrepancy?"

The question came from Ahn Seong-ho, seated at the head of the table. His voice was soft, almost gentle, carrying the flat, dangerous cadence he reserved for moments when someone’s life was about to become exceedingly complicated.

Seo-rin turned a crisp page of her report without looking up. "Not officially."

Ahn Seong-ho offered a faint, lifeless smile. "Then what seems to be the problem, Auditor Yoon?"

"The problem is that three separate infrastructure subcontractors received identical bulk disbursements from the Daehan Land Development Fund over the last quarter," she said smoothly.

"And?"

"All three firms share the exact same registered corporate director." Seo-rin lifted her dark eyes, meeting Seong-ho’s gaze with unflinching composure. "And according to state civil registries, that director died four years ago in an auto accident."

Silence descended upon the room like a physical weight.

For three agonising seconds, no one moved. Then, near the middle of the table, an elderly board member let out a dry, forced laugh. Seong-ho didn't laugh. He simply stared at her, his dark eyes calculating and cold.

"You've been digging beneath your assigned parameters again, Seo-rin," he murmured.

"I’ve been doing my job," she replied.

"Your job is to ensure the ledger appears clean to outside regulators."

"My job is to inform you when the ledger is sloppy enough to invite a state prosecutor to our door."

Across the table, another senior member leaned forward, his gold pen tapping rhythmic, irritating beats against his glass. "Your mother used to make that same self-righteous argument."

Seo-rin’s fingers tightened almost imperceptibly around her fountain pen, the metal digging into her palm.

Yoon Hye-jin. Her mother. The Council's former independent seventh seat—the incorruptible mind who had dared to question the syndicate’s shadow transactions and money-laundering pipelines. Three years ago, Hye-jin was purged from her post. Two weeks later, she was dead from what the state coroner lazily labeled an ischemic stroke.

Seo-rin had never believed the coroner’s report. Neither had the allies her mother left behind.

For three excruciating years, Seo-rin had buried her grief beneath a cold mask, infiltrating the Council’s inner financial structure under the guise of an ambitious, indifferent corporate auditor. Three years of sitting in these silent rooms, nodding at corrupt men, copying encrypted transactions, and constructing a secret secondary ledger.

She had amassed enough evidence to ruin three major banks and send a dozen executives to prison for life. But it wasn't enough to burn the Council to the ground. Not yet.

Seong-ho broke her train of thought by reaching into his coat pocket. He slid a crisp, gloss-printed photograph across the dark wood toward her.

It showed a man walking through a torrential downpour, his head lowered, his posture rigid.

Kang Tae-jun.

Seo-rin recognized him instantly, though she kept her face completely devoid of expression.

"Who is he?" she asked softly.

"The son," Seong-ho replied, watching her reaction like a hawk. "Kang Min-jae's hidden heir."

That was unexpected. Seo-rin felt a sharp spike of adrenaline hit her chest, though her breath remained steady. Min-jae had kept his bloodline buried so deep that even her mother’s old files hadn't confirmed the boy's existence.

"Where did you pull him from?" she asked.

"Out of the dirt," Seong-ho said coldly. "He was working as a mid-level architect at Daehan until his wife handed him divorce papers three weeks ago. But the moment he walked out that door, Kangseong's proxies began quietly buying up floating equity in Daehan Development."

Seo-rin looked down at the photograph again, studying the sharp line of Tae-jun’s jaw, the quiet, dangerous stillness in his eyes despite the pouring rain. "How many shares?"

"Enough to become an irritation."

A faint, mocking smile touched Seo-rin's lips. "Then he’s already far more dangerous than you anticipated."

Seong-ho’s eyes narrowed into slits. "You sound almost impressed, Auditor Yoon."

"I am curious," she corrected smoothly, closing her ledger with a dull thud. "A discarded son inheriting a titan conglomerate does not stay quiet for long. Either he is a fool who will destroy himself, or he is his father's hammer."

Seong-ho stood up, buttoning his jacket. "Find out which one he is. Pull his financial roots, track his communications, and find out if Min-jae left him anything beyond paper shares."

He didn't wait for her response before turning and exiting the suite, his bodyguards falling into formation behind him.

Only when the heavy door clicked shut did Seo-rin allow her shoulders to drop half an inch. She reached beneath the mahogany table and retrieved a secondary, encrypted mobile phone taped to the underside of her chair.

Opening a secure messaging application, she pulled up a burner contact and typed three words:

The son arrived.

Three grey dots appeared on the screen, hovered for a tense moment, then disappeared. A reply flashed:

He is angry.

Seo-rin looked down at Tae-jun’s picture resting beside her ledger. She thought of her mother’s cold, unyielding crusade. She thought of Kang Min-jae’s sudden, quiet death. She thought of the three years she had spent pretending to be a loyal servant to the monsters who had destroyed her family.

Her thumb moved across the glass screen:

Good. So am I.

She deleted the thread, cleared the cache, and slid the phone back into her pocket. As she gathered her papers, her hand brushed against a second photograph that had been tucked beneath the first.

She pulled it out. It was a recent shot—taken earlier that morning. It showed Kang Tae-jun stepping out of a black sedan outside Kangseong’s headquarters, his face cold, his posture completely transformed from the broken man in the rain.

Flipped over, the back of the print bore a line written in dark red ink:

Find out what he knows before he finds out what you know.

Seo-rin stared at the jagged handwriting, a chill creeping down her spine. The line hadn't been written by Seong-ho.

For the first time in three long, lonely years, Yoon Seo-rin wondered if she was still the hunter stalking her mother's killers—or if someone inside the Council had already stepped into the shadows behind her.
