I'm not sure as the story isn't widely known to me. But typically, short stories have a few key characters that drive the plot. It could be a protagonist who is on a journey of self - discovery or facing a conflict.
It's also possible that there are two main characters in a relationship, like a friendship or a family bond. Their interactions and how they deal with challenges together or separately could be what the story focuses on, highlighting how their actions make all the difference in the world for each other.
The main characters might include people who are at a crossroads in their lives. Maybe a young man who has to choose between following his family's traditions or chasing his own dreams in this 'world of difference'. There could also be an older character who imparts wisdom based on their experiences in a different era.
Another possible theme could be the power of perception. How one perceives things can create 'all the difference in the world'. In the story, characters might view situations differently, and this variance in perception drives the plot and the overall message of the story.
I'm not sure without reading the story, but it could be an ordinary person who suddenly discovers they have all the time in the world and has to deal with this new reality.
Since I haven't read it, I can't say for sure. But often in a novel, the main characters are those who drive the story forward, so it could be a protagonist who is on a journey to discover the 'world of difference' and some secondary characters who either help or hinder this journey.
Since I don't know the exact story, I can't say for sure. But it could be a young adventurer as the main character if it's an adventure - themed story. Maybe someone who is on a quest and has all the time to complete it.
I'm not sure as I haven't read the specific story. But usually, in a story with such a title, there could be a protagonist who is seeking or presented with the chance. Maybe it's a young person trying to make their way in a difficult world.
There could be a brave and curious explorer as one of the main characters. He might be someone who is always seeking new and unknown places. There could also be a knowledgeable scientist who accompanies the explorer. The scientist would be interested in studying the unique flora and fauna of the lost world. And perhaps there's a local guide who knows some secrets about the area leading to the lost world. This guide would be essential in helping the others navigate through the difficult terrains and avoid the hidden dangers.
I'm not sure as I don't have the specific story. But it could be a lone hero who has to brave the dangerous world on his own, using his skills and wits to survive.
In 'the way of the world short story', there could be a young man as one of the main characters. He might be ambitious and trying to make his way in the world. There could also be an older, more experienced character, maybe a mentor or an antagonist, who either helps or hinders the young man's progress. And there might be a female character who is involved in a relationship with the young man, adding a layer of complexity to the story.
I don't know as I haven't read it, so I can't say who the main characters are.
