The story might take a more somber turn. Snape could become more withdrawn and focus solely on his own pursuits. For instance, he may throw himself into his potions research even more intensely.
Lily's life could also change. Without Snape's constant presence and unrequited love, she might have a different relationship with James Potter. Maybe they have a more stable and happy relationship earlier without the complication of Snape's feelings always lingering in the background.
Maybe he starts a new life as a normal civilian. He could find a simple job in the village, like working in a shop or helping with farming.
It could also be due to some external factors. Maybe there are threats from dark forces that he doesn't want to involve Lily in. If he is getting deeper into the dark arts or some dangerous situations, he might choose to give up on her to protect her from the potential harm that could come her way because of his associations.
Well, the story could take a turn towards James finding a new purpose. Maybe he devotes himself to his studies or some magical research. He might also start to form new friendships or alliances that were previously overlooked because of his focus on Lily.
The story could take a dark turn. Without his heart, Naruto might become a soulless being, and his friends would be devastated. They might try to find a way to get his heart back. Maybe they search for a powerful sage or some ancient magic that could reverse what has been done.
The dynamic between Naruto and Sasuke would be completely different. Instead of the usual pursuit, there would be a sense of finality. Naruto might start to avoid Sasuke, which would change the way Sasuke views Naruto too.
Well, the story could take a turn where Izuku becomes more independent. He might start to shine on his own, without the shadow of Bakugou. His confidence could grow as he no longer has to deal with Bakugou's belittling.
Well, he might start exploring other aspects of the Pokémon world, like studying Pokémon behavior or focusing on Pokémon care.
Perhaps he simply lost his creative inspiration. Fanfiction writing often requires a constant flow of new ideas, and if he's been through a lot of stress or has had some personal issues, like his complex relationship with Lily still haunting him, it could dry up his well of creativity.
After Ash gives up on Charizard, the story may shift towards the development of the Pokémon that were previously overshadowed by Charizard. The fanfiction might show how these Pokémon grow and become stronger in Charizard's absence. At the same time, the fate of Charizard itself could be a major plot point. It could be on its own journey, facing new challenges, and potentially evolving further without Ash. This could set up a future reunion between them that is full of drama and excitement.
The story could develop in a way that Naruto's friends try to cheer him up and convince him to re - enter the exam. They might show him how much they believe in him and that his giving up is not the solution. For example, Sasuke could tell Naruto that he needs him as a rival to become stronger. Another development could be that Naruto starts to train secretly and then surprises everyone by coming back stronger later in the exam.
