CHAPTER 3

THE DIARY BENEATH THE ESTATE 

The walls around her pulsed like a heartbeat—steel, concrete, secrets.

Chaewon stood in the pitch-black surveillance chamber, the air sharp with chilled metal and betrayal. Jian’s voice still echoed through her skull.

“You want answers? Then find your mother’s diary—before someone else does.”

She leaned against the door, trembling—not with fear. With clarity. The pieces were forming, jagged and ugly. She hadn’t just married into a dynasty of blood and power. She’d stepped into a house built on graves, and now someone was trying to bury her under it.

She wiped her face, composed herself, and turned to the rows of monitors. If Jian had hinted at the diary’s location, he’d buried the truth somewhere close.

Because Jian didn’t threaten—he baited. Her fingers flew across the keyboard, sifting through labeled folders, tapping into the estate blueprints. Then she saw it: Bunker K7—East Wing Sub-Level. Access denied.

A storage space that didn’t appear on the architectural plans shown to city officials.

A black zone. Her mother’s name was handwritten in red over the archive tag: ‘Yoo Min.’

Her breath caught. Her mother had never once spoken about this estate. And now it was screaming her name. The terminal beeped. She pulled the drive, stepped into the corridor—and the lights cut out.

“Shit.” She yelled, they were silent everywhere.

Then footsteps. Fast and precise. She darted back inside the vault, hid behind the server stack, holding her breath.

The steel door opened.

Two figures entered.

One said. “Jian said she came down here,” A woman’s voice, familiar and smooth, Seraphina. “I don’t see her,”

Second voice replied, male, low and unfamiliar. “Should we alert Han?”

“No. Jian said let her look. But if she finds the diary… we take it.”

Chaewon’s chest tightened.

So Seraphina was involved. And worse—she was following orders not from Mr. Kim, not even from Jian... but from someone deeper in the maze. Someone who knew more about her mother’s death than anyone had admitted. She waited until the footsteps faded, then slipped out and took the east stairwell—boots pounding the iron with urgent resolve.

Sublevel K7 was a tomb. The walls were cracked limestone, laced with spiderwebs and moisture. The air smelled of mildew and memory. It was the kind of place people sealed shut for a reason. The kind of place built to hide the truth.

She followed the narrow path until she reached the rusted iron door at the end. There was no lock—only a strange, hand-carved crest. A phoenix, charred in the center, her mother’s sigil.

Yoo Min hadn’t just been a chaebol wife. She had been something far more dangerous. Chaewon pressed her hand against the phoenix, and the door creaked open with the reluctant groan of ghosts. The room inside was small. Dust-choked. Lit only by the sliver of moonlight from a cracked ceiling tile.

And there it was, a velvet-wrapped book resting on an altar of stone. The diary, she moved toward it, her hands were trembling and stopped. There was blood on the floor, old and dried.

Chaewon picked up the diary, opened the first page and read her mother’s words:

“If you’re reading this, it means you’ve chosen the path I could never finish. They tried to silence me. They’ll try again. But you are the fire, Chaewon. Not the ash.”

A noise behind her. She turned fast—blade in hand.

Jian, his eyes locked on hers. “You found it,” he said quietly.

“Did you know about this place?” she demanded.

“Yes.”

“And you let me find it, why?”

“Because it’s the only way you’ll understand.”

“Understand what? That my mother was killed for something she knew? That this house—your house—is a coffin for every secret she died to protect?”

Jian stepped closer, voice low. “Your mother wasn’t innocent.”

Chaewon’s face paled. “What?”

“She wasn’t the victim you think she was.”

He took the diary, flipped to the back, pulled a hidden fold from the spine.

Inside: a photo, black and white. Yoo Min and another woman—identical twins.

Chaewon asked. “W—What... who is she?”

Jian’s voice was cold now. “Yoo Sora. Your mother’s sister. The one who died in the fire, and so you were told.”

“She’s alive?” Chaewon breathed.

“She’s more than alive,” Jian replied. “She’s the one who sent the black feather to your window.”

“She killed my mother?”

Jian didn’t answer, didn’t need to.

“Why?” She asked again.

“She wanted the diary. The legacy your mother sealed. The key to the original blood oath contracts.”

Chaewon gripped the stone altar. “So Seraphina—she’s working with her.”

“Yes.”

“And Seojun?”

“We don’t know. But someone on the inside leaked your movements to them. Someone close to you.”

Her stomach dropped.

And just then—her phone buzzed.

One message: UNKNOWN NUMBER; ‘If you’re reading this, they’re coming for you next. Don’t trust Jian. Don’t trust your father. Don’t trust yourself.’

Attached: a photo, Seojun alive. Eyes swollen, lips bleeding. Holding a sign: ‘HELP ME.’

The location tag: Inside the Lee estate. Chaewon looked up at Jian, his expression hadn’t changed, dead calm.

“Where is he?” she whispered.

“I don’t know.”

“You’re lying.” She uttered.

“No,” Jian said. “But someone is.”

And that’s when the alarms sounded. Red light bathed the chamber.

Han’s voice crackled over the intercom. “Security breach—East wing… Hostiles inside.”

Jian grabbed her arm. “Come with me.”

Chaewon resisted. “No.”

“You want answers? They’re about to burn this entire estate to the ground to keep them hidden. Move!”

They raced up the sublevel stairs as the power flickered. Explosions rocked the west wing and smoke flooded the halls.

Gunfire. Screams.

Jian moved her behind a pillar, pulled his pistol, and fired at two masked intruders breaching the hall. Chaewon watched as he moved—ruthless, precise.

This wasn’t a CEO.

This was a weapon.

“Down here!” Jian followed, barely missing the next blast.

They emerged in the east courtyard, where fire painted the estate in gold and red. Helicopters buzzed overhead and sirens in the distance.

Back inside the estate, chaos reigned. But the diary was safe and buried in its final pages… was a name one Chaewon had never heard before, President Kang.

The page read: “He helped Sora. Funded her. Protected her. And now he wants me dead. If he ever finds out about the blood ledger, he’ll use my daughter to finish what we started.”

Chaewon’s breath caught. President Kang wasn’t just a threat, he was the man controlling all of it from the shadows. The man who had the power to break both the Kim and Lee dynasties.

Chaewon looked at her hu

sband across the burning courtyard. “Did you know?” she asked, voice barely above a whisper.

Jian didn’t answer. Because in his eyes—She saw it.
