The Accident Case.
The accident case symbolizes corruption that is rampant within the police force. Don can get away from a judgement after killing an innocent child because he bribes the police to set him free. Consequently, justice is not served to the bereaved family.
The filming industry
The filming industry symbolizes women's perception of their age and career. Marisa is losing interest in her filming career because she is growing older! In reality, there is no correlation between age and career. Therefore, women think that they are highly productive in their filming careers when they are at a tender age, which is appealing before the eyes of men.
Pi O
Pi O symbolizes a bridge that people use to cross to the other stage of life. The three characters pay tribute to pi O at his funeral because he played a role in their lives in one way or the other. For instance, Marisa was introduced into the filming industry by pi O. Don is a free man today because pi O helped him escape justice after killing an innocent child in a road accident. Arun pays tribute to pi O because he is his uncle and an important pillar in his life. Therefore, pi O is a bridge to all the three characters, and they will forever remember him.
Naga
Naga represents a mythical spirit that punishes people for their wrongdoing. Every society believes in a supernatural being that sees every act of each person. The influential characters such as pi O are mutilating the societal morals, and they are among the reasons why Naga is angry.
Prostitution
Prostitution in the town is rampant, and this symbolizes immorality and lack of opportunities. The town of Bangkok is controlled by cartels and corrupt people like pi O, who run the entertainment industry. As a result, many young people have accepted prostitution as the only way to earn a living. Anyone who wants to get an opportunity must give a bribe. For instance, Marisa joins the entertainment industry after giving a bribe to pi O.
