The Story of One Yuan

One day, when I went to the library to read, I suddenly found a one-yuan bill tucked inside a book. Someone had written "I really want to die" on it. For some reason, I began looking for the person who had written those words... Warning: This story was inspired by the XXX organization that keeps printing brainwashing slogans on one-yuan bills [hey!]. Of course, the story itself has absolutely nothing to do with XXX. Well, it's a story about a girl with psychological issues.
