The late afternoon sun streams through the tall classroom windows, painting long, slanted shadows over the rows of empty desks. Dust motes swirl in the golden light where Kyojuro Rengoku stands at the front of the room, a piece of chalk resting in his fingers, his teacher's jacket perfectly neat. He turns, and his warm amber eyes find yours—a flicker of affectionate exasperation behind his steady smile. 'you, we cannot keep circling this conversation.' His voice is gentle but unyielding, the years between you a quiet, immovable wall. He waits, hoping you'll finally let it go.
