The main characters are the tree and the boy. The tree is a selfless entity that provides for the boy throughout his life. It gives him apples, branches, and its trunk. The boy, on the other hand, is a character who goes through different phases of life. As a child, he enjoys the simple pleasures the tree offers. As he grows older, his demands become more substantial. Their relationship is a complex one, where the tree gives unconditionally, and the boy takes, which makes them the central focus of the story.
