Well, it could be a really interesting story. Maybe Jack and Lou are from different gangster families but they fall in love. It might involve a lot of drama, like trying to keep their love a secret from their respective gangs, and facing the danger that comes with being in the gangster world while being in love.
The main conflict could be their loyalty to their gangs. Since they are in the gangster world, their gangs might not approve of their relationship. They might have to choose between their love for each other and their loyalty to their gang mates.
The story that Lou San and Lou Si told was that they met Zou Jifu's son, Zou San, on their way home. They came to the Zous 'Third Family and visited the old Zou Jifu. In the chat, Zou Jifu talked about the salt merchant Yang Zhizhong in the town. This aroused Lou San and Lou Si's interest in Yang Zhizhong. They decided to investigate Yang Zhizhong's story.
One common theme is loyalty. In a gangster love story, the characters often have to be loyal to their partners as well as their gang. For example, in many movies, a gangster might be torn between his love for a woman and his loyalty to his gang buddies. Another theme is sacrifice. Sometimes the gangster has to sacrifice his love or his relationship for the sake of the gang or to protect his loved one from the dangerous gangster life.
One common element is conflict. The gangster's lifestyle often brings danger and illegal activities, which can create problems in the love relationship. For example, the threat of rival gangs or the police can put the couple in jeopardy.
There is usually the gangster himself. He is often tough, living by his own set of rules in the criminal underworld. Then there is the love interest. She could be an ordinary woman who gets caught up in the gangster's world, or perhaps she has her own secrets and strength.
Power and loyalty could be common themes. Gangsters often operate in a world where power dynamics are crucial, and in a love story within this context, loyalty to their partners as well as to their gangs can play a major role.
A good gangster love story often has complex characters, unexpected plot twists, and a balance between the criminal world and the emotional connection. The forbidden nature of the love adds to the appeal.
