I. The Quiet Aftermath
The mansion, now cleansed of immediate threat, felt unnervingly calm. Madam Park, Seok-jin, and Yeong-ho were in custody, and the Taewon Group's assets were slowly being stabilized. Chairman Kim Taehyung had resumed his duties, his days split between managing the global crisis and caring for Ha-eun (or 'Eun-ji').
Ha-eun was stable but fragile. The forehead kiss had worked like a charm, cementing a bond of trust. She was now completely dependent on Taehyung, spending her days quietly sketching abstract representations of the "Tragic Poet" and waiting for the "Briefing Hour."
But the victory was incomplete. Taehyung sat in his war room, staring at the old surveillance footage of his own house from the night Ha-eun arrived.
The question gnawed at him: Who brought her here?
The elaborate setup—faking her death, concealing her for months, and then placing her directly in his home with memory loss—was executed flawlessly. It was too risky, too precise, and too personal for Madam Park, who was focused only on financial control. Seok-jin was too volatile. Yeong-ho was a strategist, but not a ghost.
"Chief," Taehyung called his security head. "The initial investigation focused on the 'who' of the murder plot. Now, I need the 'who' of the resurrection."
II. The Ghost in the Machine
Taehyung directed his team to focus on the brief window between Ha-eun's faked fall (the body double) and her appearance in his home.
The first lead was tiny: A minuscule electronic signature—a forgotten bit of encryption—found embedded in the external security logs of the mansion. It was a single, elegant line of code designed to bypass the alarm system without triggering any alerts.
"The signature is old, Chairman," the Chief reported, pulling up the data. "It's bespoke—not commercial. It belongs to a coder who was active in the early 2000s, specialized in corporate infiltration, and completely vanished after 2008."
"Cross-reference that coder with any high-level, internal security breaches at Taewon," Taehyung commanded.
The system pinged immediately. The coder's alias, "The Ghost," was linked to the only major breach ever recorded at the company: the accidental leak of the original 'Harami Promise'—the private document where Taehyung's father promised assets to the mistress.
"The Ghost was the one who first exposed my father's secret," Taehyung realized aloud. "The person who started all this chaos was the one who brought her back. This Architect isn't after the throne or revenge; they're after rectification."
III. The Final Piece of the Puzzle
Taehyung walked upstairs to the living room, where Ha-eun was attempting to paint the floor.
"Eun-ji," Taehyung said softly. "I need to ask you about the elegant coder."
"Coder?" she asked, wrinkling her nose. "Sounds like an unkind job."
"This person might have helped you," Taehyung probed. "Did you ever have a friend who was very good with computers, but was obsessed with justice?"
Ha-eun tilted her head, her eyes clouded with the effort of searching her empty mind. She shook her head. "No. But I feel like I knew someone who smelled like old books and new vinyl. And who hated my poetry."
Taehyung ignored the poetry dig. Old books and new vinyl. An intellectual.
He returned to the war room and cross-referenced "The Ghost's" known associates with anyone at Taewon who fit the description.
The results were immediate and devastating: The only person who had access to both the old family secrets and the unique encryption code was Mr. Park's former personal secretary, a quiet, highly respected man who had seemingly retired ten years ago to run a small, independent art gallery.
"An art gallery," Taehyung murmured, a cold new realization hitting him. "The perfect cover. The only person who knew all the players, understood the chaos, and had the means to pull off the resurrection, was the one person who cared about Mr. Park's integrity."
The true, final architect wasn't one of the conspirators he had arrested. It was the loyalist who had spent years planning the perfect move to expose the family's crimes, culminating in the terrifying decision to save Ha-eun and place her in Taehyung's care—forcing the new Chairman to choose between the lie and the promise.
The Unknown Architect was watching, and Taehyung was now doing exactly what the Architect intended.
