The title doesn't disclose the main characters. However, they could be a pair of individuals with opposing traits. For example, one might be a person who has been through a lot of hardships and has become a bit prickly, like the thorn. And the other could be someone who is full of life and love, like the blossom. And the story could be about how their love unfolds with their different natures.
Well, it could be about a love that has two aspects, like the thorn which might represent the difficult or prickly parts of the relationship and the blossom representing the beautiful, positive aspects.

Some of the main characters include Meggie and Father Ralph. They play important roles in the story's development.
The main character is obviously the lion. It is the central figure around which the story revolves as it is the one with the thorn and in distress.

In the powerpuff girls blossom story, Blossom is the central figure. However, other significant characters include her two sisters. Bubbles, who is sweet and has the power of sonic scream among others, and Buttercup, the tough and feisty one. Additionally, Professor Utonium, their creator, also plays a role in the story. And then there are the villains. Mojo Jojo is a recurring bad guy, always trying to outwit the Powerpuff Girls.

I don't know for sure, but it could be a hero with the thorn wings of fire as the main character. There might also be a villain who opposes this character.
In a Four Sided Fantasy Story, the main characters might include a magical beast keeper. This person is in charge of the unique and strange beasts that inhabit each of the four sides of the world.

They are from one of the four kingdoms within the four - sided world but have been separated from their home. Their journey to return home and claim their throne is a central part of the story.
