Well - developed characters are also important. If the characters in a short story are believable and their actions are driven by good intentions, it adds to the story's goodness. For instance, in a story about a teacher who goes out of her way to help a struggling student. The teacher's character, with her patience and dedication, makes the story great. Moreover, the plot can play a role. A plot that shows how goodness overcomes difficulties or evil can make a short story really stand out. It gives the readers hope and inspiration, making them think about the power of goodness in real life.
One factor is a strong moral message. For example, if a story promotes kindness, it can be great. Like in stories where characters help each other out selflessly.
