The world is a chaos with a messy information network and a wasteful order. People in the city believe that "Safety = Happiness". They had the same facial expressions, the same smiles, the same lines, the same clothes, and the same stride. Boys and girls decide to perform a parade in front of the people of such a city. They hope that your own smile will be in full bloom. The appearance will be a new view of the city that was sunk in peace.
