An original novel of pure love. The appearance is wild, but the heart is full of suffering and aggression. Jiang Yun is a person who works hard every day. He never arrives late or leaves early. He never gives his boss a chance to find fault with him. He always looks like a dog. But after he left the police station, he changed his appearance. He was cool and domineering, and his moral character was not at all gone. The bar is his home and the dance floor is his mother. He covers all the "grey small businesses" within a ten-mile radius. He has such a wide network of connections that he is connected to the city's Rendu and Duren. Everywhere he goes, there are people offering him cigarettes. Although he doesn't smoke, he always has one in his mouth, just like that.
