Ryan finally managed to extract himself from the lobby’s mounting administrative chaos, taking the elevator back up to the sixth floor with a lingering sense of exhaustion heavy in his shoulders. Stepping into his quiet apartment, he set down a small plastic bag of basic groceries he had picked up earlier—a carton of milk, a bunch of scallions, and a compact block of tofu intended for a simple evening meal. He let out a long, weary exhale, hoping to finally anchor himself in the familiar, mundane routine of home and leave the day's phantom logistics behind on the ground floor.
Just as he reached into the bag to pull out the milk, a sharp, rhythmic knock raps against his front door. It wasn't the frantic, heavy pounding of a frustrated neighbor or the hurried tap of an overworked courier, but a deliberate, measured cadence that instantly froze his hand mid-motion over the laminate tabletop. The rattling sound vibrated through the hollow timber of the entryway, cutting straight through the low hum of a commuter train rumbling past on the rail corridor outside and signaling with quiet certainty that his Sunday night was far from over.
