The rain was not heavy, but it carried a stubborn dampness. It knocked on the floor-to-ceiling windows, making a soft "ta, da" sound, like someone tapping on the glass with their fingertips. The sound swayed through the empty room, making the surrounding area even quieter. Yan Zhan stood in front of the window, holding a slender lady's cigarette between her fingertips. The scarlet fire flickered, reflecting the thin layer of mist in her eyes. She didn't smoke, but just let the smoke rise up and down, blurring the gray sky outside the window.
"Teacher," she murmured unconsciously, her voice so soft that it was almost swallowed up by the sound of rain, "it's raining..."
After the words fell, there was only the monotonous sound of raindrops knocking on the window in the room, one after another, very much like the rain that year.
Concept: It turns out that there is really a rain that can make one person stop in the hustle and bustle of the whole world.
