You are the thick yellow leaves, the damp letter, the girl who is secretly thinking on a rainy day, the young man who is melancholy on the train for some reason, the migratory bird traveling across thousands of mountains and rivers, the slow and leisurely tinkling spring, the changing clouds, the unpredictable wind, the plot that makes people feel lost, the time that cannot be retained, and all the beautiful things in the world, except the moment when I think of you but you don't know.
