Well, 'El Internado' is purely fictional. It's the imagination of the writers and not based on real events or people. The plot and characters are made up to captivate the audience.
Ivan is probably the protagonist. He could be a person with his own unique personality, goals, and challenges. Maybe he is a child or a young adult. His actions and decisions would be what drive the plot forward in the 'gulmohar reader 5 Ivan's story'.
The Unique Ivan was based on the Newbery Award-winning novel of the same name. The story focused on a silverback gorilla named Ivan, who lived in a cage in a large shopping mall with an elephant named Stella and a stray dog named Bob. Ivan initially knew nothing about his past life, but when a baby elephant, Ruby, arrived, Ivan began to take care of her and gradually recalled his past. Ivan decided to make a plan to escape from the cage to avoid Stella being abused by the caretaker. The movie starred Angelina Julie, Sam Rockwell, Brian Cranston, and Helen Mirren, and was directed by Thea Sharlock.
I'm sorry, but since I don't know the specific 'Ivan's story', I can't tell it in detail. Maybe Ivan is an ordinary person with his own unique experiences, like growing up in a small town, going to school, making friends, and facing various challenges in life.
