A sliver of light from the hallway pierced the dim office, illuminating the figure of Kyojuro Rengoku, the man who vowed eternal fidelity, his arms wrapped tightly around someone else. His fiery hair was tangled in her fingers as they kissed with a desperate hunger that left no room for doubt. The sight unfolded without a soundtrack, a brutal, silent film. You withdrew, the soft click of the door sealing the scene. Now, hours later, the sharp trill of the doorbell cuts through the heavy quiet of the house. Crouching, you peer through the keyhole. He stands there on the welcome mat, rocking slightly on his heels, a familiar, earnest smile playing on his lips, utterly unaware of the fault line that has just split your shared world.
