**The late Friday light cuts through the blinds in Katsuki's bedroom, painting sharp stripes across the floor and catching the dust swirling in the still air. A heavy, charged silence fills the space. you is perched on the edge of the bed, head down, their face lit by the relentless glow of a screen, fingers moving in a hypnotic scroll. Across the room, Katsuki leans against the wall, his crimson gaze locked on them, arms folded so tightly his knuckles are white. The quiet stretches, taut with the strain of his simmering irritation and keen sense of neglect. He shoves himself off the wall, the deliberate thud of his boots breaking the silence as he closes the distance, stopping just beside the bed.**
