A really interesting plot could be a time - jump fanfic. For instance, the characters are separated for a few years and then reunite. During that time apart, they have both changed and grown, and now they have to rediscover their feelings for each other and deal with new challenges in their lives.
One idea could be exploring the backstories of the characters more deeply. For example, delving into the main character's childhood and how it shaped their personality in the story. Another could be creating a 'what if' scenario, like what if the two main characters met in a different setting before the events of the original story.
Maybe a plot where there are some misunderstandings between the characters that lead to a rift, and then the story focuses on how they overcome these misunderstandings. It could involve some secrets being revealed that initially seem to drive them apart but ultimately bring them closer.
One plot idea could be that the female lead discovers she's pregnant during a crucial moment in her esports career. It adds a layer of conflict as she has to balance her new family situation with her passion for the game. Another could be that the couple in the fanfiction has to face public scrutiny due to the pregnancy, but they support each other through it all.
The main plot often revolves around the relationship between the characters in the context of a particular setting, perhaps a love story or a story of personal growth within the framework of the events described in the novel.
A possible plot could be that the reader has a special ability to communicate with spirits. Smile Dog is a spirit that has been cursed and is now trapped in a form that scares everyone. The reader tries to help Smile Dog break the curse and in the process, they face many challenges together, including other malevolent spirits that don't want the curse to be broken.
A great plot could involve a character from the game trying to break free from the game's code and enter the real world. They could be on a quest to find the game creator and demand a better life for themselves and their fellow characters. This would involve a lot of action as they face obstacles both in the game world and the real world once they manage to cross over.
The plot of the 'falling into your smile fanfiction' may take different turns. It could introduce new sub - plots or relationships. Maybe it creates a more complex love triangle or adds some mystery elements to the story, like an unknown past connection between two characters.
One idea could be a crossover with another magical girl series like Sailor Moon. The Smile Precure girls could meet the Sailor Scouts and they team up to fight a common enemy that threatens both their worlds. Maybe they have to combine their powers in new and unexpected ways.
Well, the main characters are often popular choices. Their relationship and development throughout the story are usually at the heart of the fanfic.
One plot idea could be a young trainer who discovers that their master has a secret past related to a powerful and rare Pokémon. This could lead to adventures as they try to uncover the mystery together. Another idea is that the master is in danger, and the trainer has to use their skills and the bond with their Pokémon to save the master. Maybe the master has a special mission that only the trainer can help with, like protecting a legendary Pokémon's habitat.
Love is a very common theme. Given the nature of the original work, fanfiction often explores different aspects of love, such as first love, unrequited love, or love that overcomes obstacles.
Another plot idea is to have an OC who is a friend of Elio's from school. This OC could be secretly in love with Elio but then realizes the special bond between Elio and Oliver. The OC could then play a role in helping Elio and Oliver come to terms with their feelings, adding a new layer of drama and friendship to the story.
