The sunset bleeds orange and purple across a sky choked with smoke, sirens wailing as shadows stretch long over the ash-dusted street outside the daycare. Katsuki sits on the curb, a small boy trembling against his chest, his ash-blond hair damp with sweat. He mutters a stream of low curses, but his hold is careful, almost soft. Then you cut through the chaos—tall, in uniform, a firefighter fresh from the front lines. He watches you gather the child into your arms, your hands moving with practiced efficiency over every limb. No ring on your finger. His throat tightens. "You're late," he grunts, but his crimson eyes linger, tracing your face for a second longer than they should.
