The opportunity arrived when In-ah announced she had to leave the city for an urgent, midnight "meeting" dictated by the alliance. The moment her car cleared the front gates, the countdown began.

Inside the bedroom, Rora sat at her desk with her laptop open, her face illuminated by the harsh blue glow of terminal lines.

"She has a localized monitoring server hooked up to our home network and our phones," Rora explained, her fingers flying across the keyboard. "If we leave the house, a geofence alert triggers instantly on her device."

"Can you loop the feed?" Da-eun asked, peering over her shoulder, checking her watch. It was 11:45 PM.

"Better," Rora murmured, a sharp, confident smile cutting through her nerves. "I'm executing a man-in-the-middle attack on her server's DNS. I'm injecting cached data packets from last week. As far as her monitoring app is concerned, our phones are stationary in our bedrooms, and the house perimeter is completely secure. She's completely blind to us now."

With a final stroke of the enter key, the server status bar turned from a warning red to a stable, mocked green.

They were off the grid.

Ten minutes later, dressed in dark clothing, Da-eun and Rora slipped over the back fence of their property, keeping low to avoid the streetlights. They navigated the shadows of the upscale neighborhood until they reached the designated rendezvous point: the thick stone perimeter wall stretching along the back of the Kim family estate.

A soft hiss from the bushes signaled So-min’s arrival. She materialized from the darkness, a heavy flashlight and a climbing rope tucked into her jacket.

"You made it," So-min whispered, her eyes darting around the empty lane. "The guard patrol just rotated inside the main house. We have exactly eight minutes before the security grid sweeps the courtyard wall again."

They looked up at the towering, ivy-covered stone wall. Beyond it lay the ancient courtyard—the legal and physical anchor of the four families' secrets.

POV: The Keepers of the Gate

Inside the primary study of the Kim mansion, the air was thick with the scent of old paper and expensive tobacco. The room was dark, save for the ambient green glow of a multi-monitor security station recessed into the mahogany bookshelf.

Ji-hoon Kim stood by the floor-to-ceiling window, his tailored suit jacket unbuttoned as he looked down at the courtyard below. The ancient stone paths, swallowed by shadows and creeping ivy, looked completely still from this height.

"The Lee girls' network activity went completely dark twenty minutes ago," a cold voice spoke from the desk.

Ji-hoon didn't turn around. He kept his eyes fixed on the treeline at the edge of the perimeter wall. "In-ah thinks she has them contained. She thinks a month of isolation and a staged scare in the countryside was enough to make them fall back into line."

"And the Jung girl?"

"Do-hyun is sloppy," Ji-hoon replied, his voice clipping the edge of contempt. "He thinks because she returned to the city house, she’s subdued. He doesn't see the way she watches the border lines from her window."

A soft beep echoed from the security console. One of the thermal sensors along the back wall of the old courtyard registered a momentary spike in temperature—a brief, localized anomaly that disappeared as quickly as it came. The automated system logged it as a stray animal, but Ji-hoon knew better.

The younger siblings were clever. They had managed to blind In-ah's servers, and they had navigated the blind spots of the patrol shifts with precision. They thought they were uncovering a secret path.

What they didn't understand was that the courtyard wasn't a hiding place. It was a trap, specifically designed seven years ago to catch anyone who dared to look too closely at the foundation of the alliance.

Ji-hoon reached down, tapping a command into the console to override the automated patrol grid. He didn't sound the alarms. He didn't call the guards.

"Let them climb over," Ji-hoon murmured, a cold, humorless smile touching his lips as he watched three faint silhouettes drop from the stone wall into the overgrown grass of the courtyard. "Let them find exactly what we left waiting for them."

POV: The Warning from the Park Estate

Inside the sleek, minimalist bedroom of the Park estate, Chae-won sat cross-legged on her bed, her breathing shallow as she stared at the glowing tablet in her lap. Her family thought she was asleep, but she had been monitoring the secure family network channels for hours.

Her older brother had left the house in a rush twenty minutes ago after receiving an encrypted alert from Ji-hoon Kim. The message had been brief, but Chae-won had intercepted the metadata: The perimeter has been breached. They are in the courtyard.

Chae-won’s heart hammered against her ribs. She knew exactly who "they" were. Da-eun, Rora, and So-min were walking straight into a slaughterhouse. The Kims weren't trying to keep them out; they had intentionally left the blind spot open to lure them in.

Sliding off the bed, Chae-won rushed to her closet. Hidden inside the lining of an old winter coat was a cheap, plastic burner phone she had kept hidden for months. She flipped it open, her fingers trembling as she typed out a frantic text message to the auxiliary number she knew Rora kept active.

IT's A TRAP. The Kims know you're there. They overrode the patrol grid manually. Get out of the courtyard right now.

She hit send, watching the progress bar spin in the dim light of her room, praying the signal would cut through the estate's heavy interference before it was too late.

The sudden buzz of the burner phone cut through the heavy silence of the courtyard like a physical shock. Rora pulled it from her pocket, her thumb hastily unlocking the screen.

As Da-eun and So-min crowded around her, reading Chae-won's frantic warning, panic flared in their eyes.

"Is it a trick?" So-min whispered, looking over her shoulder at the looming silhouette of the Kim mansion. "Who even knows this number?"

"We don't have time to second-guess it, but we can't just run blindly either," Da-eun said, her voice tight. "Rora, can you trace where that came from?"

Rora’s fingers moved rapidly across the custom interface of her device. Because she had routing protocols configured to intercept incoming data packets on their auxiliary network, she bypassed the standard carrier masks. She began running a standard network origin trace on the message headers, attempting to isolate the cell tower routing ID and the digital signature of the sending device.

"The signal bounced off the neighborhood's private auxiliary tower," Rora muttered, her eyes scanning the rapidly scrolling lines of network metadata. "But the source device signature... it's local. It's coming from inside the Park estate lines."

"Chae-won," Da-eun realized, her breath catching. "She’s trying to warn us from the inside."

Before Rora could fully lock down the exact coordinates of the sending device, the decorative stone lanterns lining the courtyard path suddenly flickered to life all at once, bathing the overgrown garden in a harsh, blinding white light.
