This story came about after listening to Guo Jing's "Knowing" and I had the idea to write a story about an ordinary girl's crush. Not all likes in this world can be responded to. I want to write a story like this, about secret love, about a feeling of youth, looking at a person quietly, because his expression and mood are up and down. In his bright and dark days, it is like a pointer, pointing in the direction of time, where the years are passing.
