AFTER THE DIVORCE, I BECAME A BILLIONAIRE

CHAPTER 3: WHAT KANG MIN-JAE BUILT

For eight weeks, I didn't go near Daehan Development Group.

That was my first decision that caught everyone off guard. Choi Dong-wook had fully expected me to storm into their glass tower, weaponize my father's equity, and throw my newfound weight around the boardroom. He had even delivered a stern, preemptive speech warning me against the dangers of emotional recklessness.

I let him talk, but I ignored his advice—not because I trusted his instincts, but because I had finally grasped a fundamental truth.

Raw capital didn't make a man untouchable. Knowledge did.

I spent my first seven days locked inside my father’s private study in Seongbuk-dong, learning the sheer, labyrinthine scale of Kangseong Holdings. The second week was spent dissecting its forty-seven subsidiaries. By the third week, I was cataloging the key players, studying their board votes, public habits, and private debts.

By the fourth week, I finally understood why my father had spent the final year of his life living like a ghost in his own home.

Kangseong Holdings was massive, but its size wasn't what unnerved me—it was its terrifying integration. The conglomerate didn't simply operate businesses; it was woven directly into the structural bone of South Korea. Commercial banking, heavy logistics, energy grids, regional ports, municipal insurance, and political campaign funds. It held a hand in everything.

And someone had spent the last decade quietly trying to bleed it dry.

Deep inside my father's encrypted archives, I uncovered dozens of cross-referenced files pointing to a shadowy entity: the Cheonghwa Council.

Seven seats. Seven dominant sectors. One invisible syndicate that had quietly governed Hanseong's economic bloodlines for nearly forty years. They held no public titles, registered no official headquarters, and appeared on zero government registries. Yet, every major municipal development contract, maritime bid, and infrastructure grant invariably funneled through corporate entities tethered to their web.

I traced the paper trails late into the night. Shell companies with no physical offices. Management consultancies with zero employees on payroll. Dodgy contractors landing multi-billion-won government bids despite submitting blatantly inferior proposals. Money didn't just flow through these accounts; it moved in tight, perpetual circles, disappearing as illicit capital and resurfacing as legitimate corporate investment. My father had spent years mapping those exact circles.

Then, buried behind a dusty financial ledger from three years ago, I found a handwritten index card in my father’s handwriting:

The Council is not a disease infecting the system. It is the bloodstream.

I stared at those words until the ink blurred. Tucked right behind the card was a secondary document—a heavily redacted toxicology report from a private European laboratory.

The report detailed a specialized synthetic compound capable of triggering acute myocardial paralysis while mimicking standard cardiac arrest. It left virtually zero chemical residue, degrading completely within hours of entering the bloodstream.

At the bottom of the page, my father had circled a single line in dark red ink:

Standard forensic toxicology will not detect it.

I leaned back in the heavy leather chair, staring at the ceiling of the quiet study. The air in the room felt suffocating. He hadn't merely suspected his enemies were closing in—he had held the literal chemical proof of his impending execution in his hands. He knew he was breathing on borrowed time, and yet he had stayed at his desk, silently building a fortress for a son he couldn't even hold.

A profound, aching weight settled into my chest. For six years, I had resented my biological father for abandoning me to poverty, for letting me suffer the cold dismissals of Han Mi-sook and the casual cruelty of Han Do-jin. But looking at these files, the harsh truth hit me like a physical blow.

He hadn't kept me at a distance because he didn't care. He had kept me hidden because he knew precisely what happened to anyone who stood in the way of the Council. My entire ordinary, miserable life had been a meticulously engineered safe house.

The sudden ring of my secure phone shattered the silence.

I picked it up, my voice steady. "Yes?"

"We've located another key stakeholder in Daehan Development," Dong-wook’s gravelly voice came through the speaker.

"Who?"

"Director Park Jin-woo. He holds a four percent voting block on the executive board. He's currently leaning toward Ahn Seong-ho’s bloc, but his logistics firm is heavily overleveraged."

I sat up straighter, my eyes narrowing. "Can we buy his debt?"

"We have the capital to absorb his liabilities by tomorrow morning," Dong-wook replied. "If we execute the buy-out, we force his vote."

"Do it immediately. Don't give him room to negotiate with Seong-ho."

There was a brief pause on the line. Then Dong-wook spoke again, his tone dropping an octave. "There is one more matter, Young Master."

"Speak."

"Someone has been making subtle inquiries about your past," he said quietly. "Traced back to a private intelligence firm in Yeouido. They're pulling your old academic records, your tax filings from your time at Daehan, even your medical history."

I looked toward the rain-slicked window overlooking the dark gardens. "Ahn Seong-ho?"

"We cannot confirm yet."

"Find out who hired them," I commanded coldness creeping into my words. "And leak just enough noise to keep them chasing ghosts."

I ended the call and pulled the final file from my father's desk drawer.

Inside was a single black-and-white photograph taken at a private estate years ago. Seven men sat around an oval mahogany table. Six faces were clear, crisp, and recognizable—titan figures of industry, banking, and media. But the seventh chair at the head of the table had been deliberately cropped out of the print.

Underneath the photograph, my father had written a final, unsettling warning:

One of them is closer to you than you think.

I stared at the cropped edge, my mind racing through every face I had encountered over the last six years—every corporate executive, every handler, every shadow in the background.

Before I could digest the thought, my phone vibrated again.

I glanced down. The caller ID was completely suppressed.

I swiped the screen and pressed the phone to my ear. "Hello?"

Silence stretched across the line for three agonizing seconds. I didn't say another word, listening intently to the faint, steady breath on the other end.

Finally, a woman’s voice—cool, sharp, and entirely unhurried—echoed softly through the speaker:

"If you want to survive the month, Tae-jun... you shouldn't trust the solicitor."

The line went dead.
