Variables

Kai waited until the neighborhood was silent. He didn't think anyone would try to come in. He then locked all doors and windows. The notes were spread across his desk again.

Diagrams. Handwritten equations. Terms repeated with precision. Spacial Threshold. Energetic Strain. Layer Contact Duration.

He flexed his fingers slowly. Nothing happened. He focused on the scar beneath his shirt. The memory of the alley. The pressure. The folding. The snap. His breathing slowed deliberately. He imagined the space thinning. Not dramatically. Just slightly. The tingling began almost immediately. Subtle. Under the skin. He didn't panic. He observed. The threads surfaced faintly along his ribs — barely visible beneath the fabric of his shirt. They weren't glowing. They were tracing his bones. Like tension lines drawn across him.

He extended his hand. One thin strand slipped from his fingertip. It didn't flare outward. It hovered. Uncertain. He pushed it forward and let it brush the edge of his desk. The wood dented inward slightly. Not broken, indented like the wood itself was manipulated. The thread retracted instantly. Kai stared at the surface. The indentation remained. He swallowed. "High external effect," he murmured. Stage One means activation. Not control. He tried again.

This time, instead of reaching outward, he focused on himself. On the space around him. On the feeling of thinness. The air in front of his desk wavered. Barely visible. Like heat rising from pavement. He stood slowly. The room didn't vanish this time. It layered. His bedroom remained visible — but overlaid with the same dim, endless expanse from the alley. The Veil. Not fully crossed. Partially aligned. His heartbeat quickened. The threads pulsed faintly. The overlap lasted three seconds. Four. Then pressure built behind his left ribs where the mark lay sharply. The space snapped back into singular form.

He stumbled against his desk. Breathing harder now. He looked at the clock. Eleven seconds had passed. He wrote it down immediately. Entry possible. Duration 11 seconds. Strain increases rapidly. He leaned back in his chair. If Stage One allowed entry— Then higher stages must reduce strain. Not grant entry. Improve stability. He stared at his father's notes again. One line stood out, written darker than the rest: The Veil does not resist. It has requirements. Kai exhaled slowly. "That wasn't resistance," he muttered. "Im too weak." ⸻ The next day, he felt sharper. More aware of space. More aware of gaps.

During lunch, he sensed someone approach before hearing footsteps. Yuna stopped beside him. "You look tired," she said evenly. He glanced up. Her tone was casual. Almost neutral. "Studying," he replied. "For what?" He shrugged slightly. "Tests." She studied his expression carefully. "You live near the east block, right?" "Why?" "Just asking." Her gaze shifted briefly to the scar area beneath his shirt. Not intentional but Kai took notice. "You ever take the alley between Marrow and 8th?" she asked. His pulse remained steady. "Sometimes." "It's unstable." He blinked once. "What?" She held his gaze. "Heat distortion. Spacial compression." He shrugged again. "Sounds like construction." A pause. She watched for a crack in his expression. There wasn't one. "You didn't notice anything unusual?" she asked. He tilted his head slightly. "Like what?" Her eyes narrowed just a fraction. Then she leaned back. "Nothing." Silence stretched between them. Not hostile. Measured. "You're sure nothing happened?" she said finally. "It can be dangerous." He met her eyes. "So can assumptions." For the first time, something shifted in her expression. Not emotion. Recognition. He wasn't confused. He was aware. But he wasn't revealing anything. She straightened. "Be careful around that alley," she said calmly. Then she walked away. Kai watched her cross the courtyard. She didn't look back.

He pressed his fingers lightly against his ribs. The threads stirred faintly. She knows something. Across the yard, Yuna typed a short message without breaking stride. Subject composure evaluated. Possible awareness. No confirmation of a mark. She paused after receiving the next line.

"Continue observation and find a connection."
