Anyone who picks up the story and reads it can be the reader of the story. It could be a child looking for an adventure in the pages, an adult seeking relaxation, or a student studying literature.
The reader of the story is typically a person who is interested in the genre of the story. For example, if it's a mystery story, mystery lovers are likely to be the readers. They are the ones who engage with the plot, the characters, and the overall narrative.
People who enjoy using their imagination are likely to be readers of novels. Novels have the power to create entire worlds within their pages. A reader of novels can visualize the settings, characters, and events described in the book, and this allows them to escape from their own reality for a while and explore new and exciting places and ideas.
The villain or the character who opposes the protagonist can be the antagonist. For example, in the story of 'Snow White', the Queen is the antagonist as she tries to harm Snow White.
Often, the character who actively opposes the protagonist and causes harm or creates obstacles can be the villain of the story. For example, in the 'Harry Potter' series, Voldemort is clearly the villain. He murders, spreads fear, and tries to take over the wizarding world, which is in direct opposition to Harry Potter, the protagonist.
The author can be seen as the person who tells the story. For example, in a novel, the author creates the plot, characters, and setting, and then uses words to convey the story to the readers.
An actor can be seen as a person who tells a story as well. Through their performances on stage or in films, they embody characters and act out a story. They use their body language, tone of voice, and emotions to tell the story written by the scriptwriter to the viewers.
In many stories, the good guy can be the one who stands up for justice. In 'To Kill a Mockingbird', Atticus Finch is the good guy. He defends a black man in a racist society, even though it brings him a lot of trouble. He believes in equality and fairness and is willing to fight for it.
Another possibility could be an antagonist who is so cunning and manipulative that they are the force that sets the whole story in motion. They create the conflict and challenges that the other characters must face. Their actions and schemes are what keep the story going and the other characters on their toes. So, in this sense, they can be considered the mastermind of the story.
Often, the protagonist who shows kindness, courage and justice can be the good guy. For example, in the story of 'Harry Potter', Harry Potter himself is the good guy. He is constantly fighting against the dark forces, protecting his friends and the wizarding world.
Even a pet can be the 'star of love story' in some cases. For instance, if a dog helps two strangers to meet and then their relationship develops. The dog's presence and its role in their relationship make it an important part, like a star that influences the whole love story.
In many adventure stories, the loyal sidekick can be seen as a good guy. They stand by the main character through thick and thin. Take Robin in the Batman stories. He assists Batman in fighting crime, using his own skills and courage, and always has the back of the hero.
