Who are the main characters in 'a high dive short story'?

Since I haven't read it, I can't say for sure. But it could be the high diver himself or herself as a main character. There might also be a coach, a rival diver, or family members who play important roles.

The main characters in 'a high dive short story' could vary. It might be centered around an individual high diver, whose story the narrative follows. There could be a mentor figure, perhaps an older, more experienced diver or a coach, who imparts wisdom and training. There might also be a love interest, who either supports or complicates the diver's focus on high diving. And of course, there could be competitors, other divers who are vying for the same accolades, creating a sense of rivalry and competition within the story.
