There could be a young couple. The boy might be an artist who loves to create balloon sculptures, and the girl is charmed by his creativity and they fall in love.
It could be a lonely person who finds love through a balloon delivery service. The delivery person, who always brings beautiful balloons, and the recipient gradually develop feelings for each other, and they become the main characters in this special 'balloon love story'.
The two main characters are the cactus and the balloon. The cactus, which is often associated with dry and arid places, and the balloon, which is a symbol of fun and lightness. Their contrasting natures make them interesting main characters in this love story.
Obviously, the boy is one of the main characters. He is the one who has an interaction with the balloon. And the balloon itself is also a main character. It's the object that the boy is interested in, and around which the story likely revolves.
Since I don't know the specific 'black balloon story', I can't say for sure who the main characters are. It could be a child, or maybe an adult who has some special connection to the black balloon.

The main characters in the balloon boy story were the Heene family, especially Falcon Heene, the boy who was supposedly in the balloon.
Since I don't know the exact 'hot air balloon story', it could be the pilot of the balloon. Pilots are often central characters as they control the balloon's flight.
