One day when I was tossing and turning, I suddenly discovered that so many people have been lost around me. It turns out that some people have lost touch with me without knowing it. They once stood on one bank of the river of my life, casting deep reflections. From this, the river became alive. But after all, it is just an invisible illusion frame by frame. As they leave the shore one by one, the illusion disappears, but my river will not stop.
