My name is Gu Kai, I am in my twenties, and I have the toughest job as a courier in the city. Every day, in the wind and rain, I ride my little electric donkey through the corners of the city. I earn enough money to eat and drink, but I still have a long way to go before I can sleep in peace. Others see me as someone who looks polite and looks a little silly when I smile, and they all think I am a silly and sweet person with no temper. Only I know that I can spout dirty words from the east to the west of the city, but I usually keep my mouth sealed just to make a living.
