Well, in some 'kakashi love story fanfic', there could be a plot where Kakashi falls in love with a fellow ninja from his village. They might start off as friends, training together and gradually realizing their feelings. For example, they could be on a mission together and Kakashi saves her life, which makes him see her in a new light and the love story begins.
One possible plot is that Kakashi meets a mysterious girl from another land. She has different values and skills, and at first they clash. But as they get to know each other better, Kakashi discovers her kind heart beneath her tough exterior and falls for her. This could lead to a lot of adventures as they try to bridge the gap between their two worlds.
Some fanfics have a plot where one of them gets injured severely, and the other has to take care of them. This kind of plot really shows the depth of their care for each other. Like in one fanfic, Gai gets hurt during a mission and Kakashi is by his side throughout his recovery, and during this time, their relationship deepens in unexpected ways.
One interesting plot could be Sonic and Amy going on an adventure together to save a magical land. Along the way, they face many challenges that make them rely on each other more and realize their deep feelings for one another.
Maybe a story where two rival trainers start off hating each other but as they both care for the same injured Pokemon, they gradually develop feelings for each other. They then have to balance their rivalry and new - found love while still competing in Pokemon battles.
One interesting Kakashi love story fanfiction could be about him falling in love with a fellow ninja from another village. In this story, they meet during a joint mission and at first, they are suspicious of each other. But as they face various challenges together, they start to develop feelings. Their love is tested by the politics between their villages, yet they strive to be together.
Perhaps Videl gets amnesia and forgets who Gohan is. Gohan then has to re - introduce himself and make her fall in love with him all over again. He takes her to all the places that were special to them and shares their memories, which is a really sweet and emotional journey in the fanfic.

In 'freaks in love fanfic', there could be a plot where the lovers are from different worlds within the freak community. For example, one might be a social outcast because of a physical anomaly and the other due to a strange power they possess.

This could also involve them making new friends within the community and changing the way others view them.
One interesting plot could be the team facing a new and extremely powerful enemy that forces them to develop new jutsus and strategies. For example, a villain who can manipulate time, making their regular combat skills ineffective.
Another plot could be about the babies' growth and development in the ninja world. They start to learn about the different clans and jutsus from a very early age. For example, Naruto's baby might be super curious about the Uzumaki clan's secrets, and Sasuke's baby could show an early inclination towards the Sharingan and the Uchiha clan's history. This would be a story of their journey from being innocent babies to potential great ninjas.
Well, in some time travel Kakashi fanfictions, there's a plot where Kakashi goes back in time right after Obito's 'death'. He tries to save Obito in a different way, not just by taking his eye. He could change the whole course of events that led to the formation of Akatsuki and the many tragedies that followed. This would completely rewrite the story of Naruto in many ways.
