Who are the main characters in the other two short story?

I don't know as I don't have information about the 'the other two short story'. Maybe it could be a young protagonist and an old mentor type of character which is a common combination in many short stories.

Since I'm not familiar with these particular short stories, I can only speculate. It could be a group of friends as main characters, and the story could be about their adventures or conflicts within the group. Another possibility is that the main character is a loner, and the story is about their internal struggles and how they interact with the world around them. There could also be a family - centered story with parents and children as the main characters, and the plot could deal with family dynamics and relationships.

Without reading the actual short stories, it's impossible to say for sure. But often short stories have a central character around whom the plot revolves. This character could be a hero - like figure, facing difficulties and trying to overcome them. There might also be secondary characters who either support or oppose the main character's journey. For instance, in some stories, there could be a villainous character who creates obstacles for the main character to test their strength and determination.
