There could also be characters who are a bit skeptical. Dolores, with her ability to hear everything, might be able to tell if the fanfiction is based on real events or just pure imagination. If it's too far - fetched, she might be less impressed. However, overall, most characters would probably see it as a form of celebration of their story and be at least somewhat entertained by it.
The younger characters in Encanto like Antonio would be excited. He loves stories and new ideas, so Mirabel fanfiction would be like a new adventure for him. He might want to share it with his animal friends. And Dolores, with her ability to hear everything, might already know about the fanfiction. She could be either intrigued or a bit worried depending on how the fanfiction is being received by the rest of the village. If it's causing a stir, she might be concerned about the family's reputation, but if it's positive, she would likely be quietly supportive.
If the grandfather is very warm and accepting, Shikaneji would feel relieved and happy. They might open up more about their relationship and their dreams. Nejire could start chatting excitedly about their future together, and Shinsou would relax and join in the conversation more. However, if the grandfather is not so friendly, they would be disappointed and perhaps a bit defensive.
In the 'Dolores Roach True Story', Dolores Roach is likely a real - life person on whom the story is based. She could be an ordinary woman with an extraordinary story, perhaps facing hardships, making mistakes, and learning from them throughout her life.
They might be really surprised. Some characters could be flattered by the positive portrayals in the fanfiction. For example, Mirabel might be happy to see different interpretations of her story and how she's seen as a hero in some fics.
