There's also 'Obito's Unlikely Bond'. In this fanfic, the OC is a healer who stumbles upon a wounded Obito. Their relationship starts off rocky but gradually turns into something deeper.

Yes, there might be. There are many creative fanfiction writers in the world who like to combine different fictional universes. Some might have come up with the idea of integrating Harry Potter and Obito Uchiha. You can try searching on popular fanfiction websites like Fanfiction.net or Archive of Our Own to see if there are any such stories.
Good writing style also matters. Vivid descriptions of the settings, emotions, and actions can bring the story to life. For instance, when describing Obito's Sharingan abilities, it should be detailed and exciting. The dialogue between the OC and Obito should be believable and help to move the story forward, whether it's a heated argument or a tender moment.
A possible plot could be that in a parallel dimension, Harry Potter is actually Obito Uchiha reincarnated. He is born into the wizarding world but still has some latent memories and powers from his past life as Obito. As he grows up in Hogwarts, he discovers his unique abilities which are a blend of magic and the powers of the Sharingan. He uses these to uncover a hidden conspiracy within the wizarding world that is related to an ancient dark magic that has similarities to the dark powers in Obito's original world. Along the way, he has to deal with his own inner demons, just like Obito did, and also face off against the traditional threats in the Harry Potter universe like Voldemort and his followers, but with a whole new set of skills and a different perspective due to his dual - natured identity.
When Naruto was in the Uchiha family, he devoured Naruto and obtained nine tails. The title of the book could be called " Nine-Tailed Demon Fox: Uchiha Sasuke." The title combined the elements of Nine-Tailed Fox and Naruto to describe the process of the protagonist obtaining the nine tails and finally becoming a powerful ninja.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
The fanfiction could explore how Obito's identity revelation affects his relationship with the Akatsuki. Some members may feel used or deceived, while others might see it as an opportunity. It could also show how Obito's true self starts to form new bonds or break old ones within the organization, depending on how his true intentions are perceived.
One possible motive could be to use Sakura as a bargaining chip. If he has some sort of plan against Naruto or the Hidden Leaf Village, Sakura, being a close comrade of Naruto, could be very useful. He might think that by restraining her, he can force Naruto to come to a certain location or make concessions.
One popular sakura and obito fanfiction is 'The Unseen Bond'. It delves into a world where Sakura discovers Obito's hidden past and tries to help him find redemption.

And there's also 'A New Path for Sakura and Obito' that shows them working together to face challenges in the ninja world.
