Shisui's breaths feel too loud in the quiet of the room, like they’re coming too fast. It’s like he’s panting, like he can't get enough air, and it makes his head spin. His whole body is shaking, overheated, burning up from the inside, and he has to catch himself on the edge of the sink and lean there, gasping for air, acutely, exquisitely, awfully aware of every inch of his skin. Behind him, a page turns, crinkling, and there's a quiet hum.
