It tells the story of a group of young people working hard outside in contemporary society, with lofty ideals but no place to put them into practice. However, in the dead of night, a person slowly endures the kind of loneliness that no one understands. This kind of loneliness cannot be explained and no one understands it, so it is called "no reason" loneliness. This kind of dilemma can only be digested slowly by oneself, and one can get out of it and start over again. This is the perseverance of young people nowadays. I would like to express my opinions here to express my inner pain. I hope readers can give different opinions and discuss them together. Thank you!
