Ai Miaomiao's tortuous childhood and her experiences as an adult were different from others. She thought that her life was destined to be a lonely journey, but there were also many people who could warm her heart. Some people left and some people still existed, but she never thought that she would change her life because of one person. That person who seemed inconspicuous at first or even weak enough to need to be rescued by herself was entangled with her destiny and was inseparable. But what she didn't know was that this long period was 20 years. When Ai Miaomiao came to this world, she was quiet. The only thing that remained unchanged was that she was lonely at the beginning and still lonely in the end. No one knows that what Miaomiao fears most is loneliness, so in the end Miaomiao chooses to take her loneliness away from this world that scares her.
