AFTER THE DIVORCE, I BECAME A BILLIONAIRE

CHAPTER 14: THE MEASURE OF A Commute

POV: Seo-rin

Sleep was a luxury I could not afford, a weakness that felt dangerous in a room full of ghosts.

My eyes burned, dry and inflamed from hours of staring into the harsh blue glare of my laptop. The morning light was barely beginning to gray the edges of Mapo, painting the wet roofs outside my window in dull shades of slate and tin. I was running entirely on cold black coffee and the raw, electric surge of adrenaline left behind by my mother's private calendar.

I buried myself deep inside the Cheonghwa Council's shadow ledger, determined to strip away the noise and find the hand that had forged Tae-jun's administrative security key.

It was tedious, microscopic work—the kind of soul-crushing numerical analysis I had trained myself to disguise as routine administrative boredom. For three hours, I cross-referenced every encrypted wire code, every rerouted infrastructure dividend, and every manual ledger override against Kangseong Holdings’ internal staff directory.

Then, at six in the morning, a distinct, mathematical pattern surfaced.

A cluster of internal financial approvals, spanning eighteen months, had been quietly routed through Kangseong’s primary finance division. They were executed using an administrative clearance level that shouldn't have existed without direct executive sign-off, all originating from a single ledger account.

The name on the digital file was Yoo Chang-min.

I stared at the screen. I had never heard the name before, nor had I ever met the man in person. But in a network where every ghost left a footprint if you looked closely enough, his signature was written across six different sub-ledgers.

By nine in the morning, I had arranged a meeting.

I framed the request around a routine internal audit—a low-stakes review of recent subsidiary transfers between Daehan Development and Kangseong’s regional logistics units. It was the kind of dry compliance work no one in executive management ever questioned.

Yoo Chang-min received me in his ninth-floor office with disarming warmth.

He was in his late thirties, sharply dressed in a tailored navy suit, with a polished, open expression that seemed completely incongruous with the shadowy mechanics of Kangseong’s upper management. He was quick to offer tea, self-effacing about his recent promotion to Senior Vice President of Finance, and remarkably unbothered by my sudden arrival.

"Director Yoon," he said smoothly, sliding a stack of leather-bound audit binders across his clean desk without a single moment of hesitation. "I'm always glad to see compliance taking an active interest in our regional accounts. Transparency is the only thing keeping this building afloat these days, isn't it?"

I studied him as I flipped through the pages. He didn't sweat. His pulse didn't flutter at his throat. He didn't exhibit any of the subtle, physical micro-expressions of a man sitting across from an auditor while hiding a forged security key.

In fact, before I could even bring up the specific wire transfer anomalies I had flagged, Chang-min pointed one out himself.

"If you turn to page fourteen," he noted, leaning forward with an earnest, collaborative smile, "you'll see a two-million-dollar discrepancy in the Q2 logistics reconciliation. I caught it late last Thursday and flagged it for internal review. It looks like an administrative routing error, but I wanted to make sure it was fully documented before your team ran your sweep."

It was a masterclass in corporate deflection. Smooth. Seamless. Impeccably executed.

He offered zero resistance, handed over complete file access, and framed potential red flags as evidence of his own diligence. Yet, as I thanked him and left his office, a cold, persistent residue of unease lingered at the back of my neck.

Men who have nothing to hide are never that eager to help you look.

The afternoon rain had turned into a steady, freezing drizzle by the time I left the building. Instead of taking a taxi, I chose to walk home through Mapo’s narrow, winding back streets—a labyrinth of steep stone steps, dim residential alleys, and covered market stalls.

Three blocks into my walk, I felt it.

Footsteps.

It wasn't a sudden, dramatic realization, but a subtle shift in the ambient sound of the street. The footsteps behind me maintained a pace that was entirely wrong for a casual evening walker, and the sharp click-clack of hard leather soles was wrong for a jogger. They matched my turns with just enough delayed precision to seem coincidental to anyone else.

I didn't run. Running was a confession. Running confirmed fear, and in this city, fear invited a bullet or a quiet shove into an unlit alley.

I maintained my steady, measured stride, turning sharply into the narrow, crowded stalls of the Mapo fish market. Smells of wet asphalt, salt water, and cold brass filled the air. I doubled back behind a row of hanging tarps, ducked through an narrow alleyway between two brick residential buildings, and emerged three blocks away near the canal.

The footsteps vanished. I had lost whoever was following me—or so I thought.

Ten minutes later, I stood outside my apartment door, my breath coming in quiet, ragged hitches. My key trembled slightly in the lock as I turned the deadbolt, a sudden wave of cold exhaustion threatening to pull the floor out from under my feet.

What unsettled me far more than the tail itself was the terrifying realization of where I had been followed.

They hadn't just followed me through Mapo. They had anticipated my route.

It was a specific, highly unpredictable back-alley path I used precisely because it avoided main thoroughfares and security cameras. It was a route designed to break tails, known only to three people in the world: my private handler inside the Council's compromised network, Tae-jun, and Yoo Chang-min.

During our meeting that morning, when Chang-min had politely asked if I required a company driver, I had made an offhand, casual remark about preferring the quiet walk home through the old Mapo market steps.

I stood frozen in the dark entry hall of my apartment, my hand still resting on the cold metal doorknob, running through every logical permutation of what that meant. Every scenario led back to the same harrowing conclusion: Yoo Chang-min was not just an accountant. He was watching me.

Before I could lock the door behind me, my phone vibrated in my coat pocket.

A sharp, violent buzz against my ribs.

I pulled out the screen with cold, numb fingers. It was an encrypted text message from an unregistered local number, originating from somewhere inside the very city I had just walked through:

You lost me for three blocks. Impressive.

Next time won't be a test.
