The sky was gray.

Lin Ye lay on the school rooftop, staring at the sky. He always felt like he had forgotten many things, but they didn't seem important enough to remember.

It was like having something stuck in your teeth after a meal, but when you try to touch it, there's nothing there.

The rooftop breeze was gentle, the dim sky lacked any chill, and Lin Ye felt his limbs go soft. A sense of lethargy washed over him, sapping his energy.
