For So-min, the thirty days following her escape from the countryside were defined by a suffocating, hyper-vigilant quiet.

When she had slipped back through her basement window that night, barely catching the last bus before the valley roads froze over, she had expected a storm. She expected Do-hyun to be waiting in the dark kitchen, or Hobi to confront her with the tracking logs from her phone. But the silence that met her in the city house was worse. No one asked where she had been. No one mentioned the countryside. The older siblings simply watched her with cold, calculating eyes across the dinner table, as if waiting for her to make a mistake.

The paranoia forced her into a total media blackout. For four long weeks, she didn't send a single text to Da-eun or Rora. She kept her phone locked in a drawer, terrified that any digital footprint would blow their cover completely or bring the masked attacker down on them again.

Instead, So-min spent her days playing the part of the obedient younger sister, all while keeping her eyes wide open.

Every time she walked past the grand windows overlooking the estate, her gaze shifted past the manicured lawns. From her vantage point, she could just see the edge of the adjacent property—the sprawling, imposing grounds of the Kim family mansion.

Locked inside her own home, she spent hours sketching out the perimeter lines from memory. She didn't think about the J.Y. and Y.E. initials anymore; they were a dead end for now. Instead, she focused entirely on the architectural anomaly Rora had spotted in the blueprints.

The ancient, high-walled courtyard stretching behind the Kim mansion wasn't just a garden. It was the geographic center where all four families' hidden histories converged. Every ledger, every old land deed, and every broken alliance pointed directly to the soil beneath that specific courtyard.

By week four, the bruises from their frantic retreat had faded, and the terrifying memory of the shattered window had settled into a cold, hard resolve. The families thought the younger girls had been properly frightened into submission. They thought the threat was neutralized.

On the thirty-first night, So-min finally pulled her auxiliary phone out of the drawer. The battery was low, but the screen lit up, casting a faint blue glow over her dark bedroom.

She opened the encrypted app, typed in the old childhood gateway code, and sent a single, untraceable line to Da-eun and Rora.

The dust has settled. It’s time to move on the Kim courtyard.

POV: The Waiting Game

For Da-eun and Rora, the month of silence felt less like a retreat and more like being under house arrest.

After In-ah practically dragged them back to the city, the atmosphere in their own home became unbearable. The shattered glass from the cabin window was replaced by a heavy, suffocating surveillance. In-ah barely spoke to them, but her presence was everywhere—her eyes lingering on their backpacks, her footsteps pacing the hallway late at night. They were being watched, not just by their sister, but by the invisible network of the alliance.

Rora spent the first two weeks jumping at every sudden sound. Every time a car idled too long outside their gate, her mind immediately painted it black. She kept her phone completely off, tucked away inside a hollowed-out textbook.

But fear eventually gave way to a restless, burning frustration.

While Da-eun kept up appearances by sticking strictly to her daily routine, Rora spent her nights staring at the ceiling, mentally reconstructing the architectural layout of the Kim estate. They had agreed to leave the J.Y. and Y.E. initials alone—the code was too dangerous, and the woods were compromised. The city was where the true answer lay.

On the thirty-first night, the silence finally broke.

Sitting on the edge of Rora's bed, Da-eun watched as Rora pulled the auxiliary phone from its hiding place and powered it on. The screen flickered to life, and a second later, a single notification popped up from So-min:

The dust has settled. It’s time to move on the Kim courtyard.

Da-eun let out a breath she felt like she’ve been holding for a month. She looked at Rora, whose eyes had lost their terror, replaced by a cold, sharp focus.

"She's right," Da-eun whispered, leaning over the screen. "We've played dead long enough. They think they broke us."

"The Kim mansion's security resets its patrol grid every Sunday at midnight during the shift change," Rora murmured, her thumbs flying across the encrypted keypad to reply. "That gives us exactly a ten-minute blind spot to reach the old courtyard wall."

The piece of paper with the blueprint layout was memorized. The fear was still there, coiled tightly in their chests, but the month of isolation had done its job. They weren't running anymore. They were planning a break-in.
