In this alternate storyline, it could lead to major changes in their relationship and the overall plot. Maybe Obito's feelings would prevent him from going down the dark path he did originally.
If Obito loved Kakashi, it could have brought a whole new dynamic. Maybe they would have worked together more closely, or Obito's love could have been a source of internal conflict for him.
Well, if Obito loved Kakashi, it might have made him more hesitant to pursue his extremist goals. It could have also affected their teamwork and how they interacted with others in the ninja world.
One great Kakashi x Obito fanfiction is 'The Bonds We Share'. It delves deep into their relationship, exploring how their past experiences shape their interactions in a post - war Konoha. It shows their growth and how they come to understand each other on a deeper level.
One idea could be a story where Female Kakashi and Obito are on a mission together in a mysterious land filled with ancient magic. They have to rely on each other's skills to survive and in the process, they start to see each other in a new light.
Well, it could be about Kakashi finally finding Obito after a long search. Maybe Obito has changed a great deal, and Kakashi has to come to terms with this new version of his old friend. They might have a battle first due to their different paths, but then they start to talk and remember their past together, like their time as teammates in Team Minato.
One popular theme is redemption. Given Obito's past actions, many fanfictions explore his journey towards redemption and how Kakashi plays a role in it. For example, Kakashi might be the one to finally make Obito see the error of his ways.
In an 'Obito kills Kakashi' fanfiction, it could start with a long - standing grudge. Maybe Obito discovers some new information that he believes Kakashi has been hiding from him all these years. This enrages him so much that he decides to take revenge and kills Kakashi in a fit of rage during a battle.
Kakashi could use his Sharingan to analyze Obito's moves and find a weakness in his defenses. Since he has the Sharingan, he might be able to predict Obito's attacks and counter them effectively, eventually finding an opportunity to break free.

A plot could be that there is a prophecy about Female Kakashi and Obito saving the ninja world together. They initially don't believe it, but as events unfold, they are forced to work together. Through their journey, they develop a deep connection and eventually fall in love.
A great fanfiction idea might be a story that delves into an alternate universe where Kakashi was the one who fell into the dark side instead of Obito. This would completely change their dynamic. Obito would then be the one trying to save his former friend, and it could explore themes of redemption and the power of their bond in a very different context.
Some fanfictions might explore the emotional aspect of their fight. For example, how their past friendship affects the battle. Maybe Kakashi hesitates to strike a fatal blow because of their shared history.
