A coward is afraid of happiness, will be hurt when touching cotton, and sometimes will be hurt by happiness - Osamu Dazai, "Disqualified in the World"
Xu Mianzhi is such a coward. When there are waves in the calm water, and when there is a slight fluctuation in his heart, Xu Mianzhi chooses to shrink into his own shell, transfer to another school silently, and run away silently without any nostalgia for the city he has lived in for more than ten years. Start your life over again in a place where no one knows you.
