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.
If Konan gets pregnant in fanfiction, their relationship would become much more intense. They would have to rely on each other more. Naruto would become more protective of Konan, and Konan would have a deeper connection with Naruto due to the baby. They would start to think about building a family together, which is a big change from their previous individual lives as ninjas.
Naruto would probably be more popular. He has that outgoing and friendly personality that draws people in. He'd be the kind of guy who is always involved in school events and is friends with everyone from the jocks to the nerds.
A good one is 'Naruto and Konan: Allies in the Shadows'. Here, they start as unlikely allies but gradually grow to trust and rely on each other. The fanfiction has some great fight scenes and also shows the development of their bond outside of combat situations.
Konan and Itachi are from the Naruto series. However, in the original story, there is no indication of a romantic relationship between them. But we can imagine one. Konan, with her calm and mysterious nature, might be attracted to Itachi's complex and conflicted personality. They could meet in the shadows of the ninja world, gradually understanding each other's pain and secrets, and slowly fall in love as they find solace in each other's presence.
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. Another great one could be 'Sakura's Encounter with Obito', which focuses on their chance meetings and how it gradually changes their relationship. And there's also 'A New Path for Sakura and Obito' that shows them working together to face challenges in the ninja world.
The sad story of Obito and Rin is a key part of the Naruto narrative. Obito was a young ninja with big dreams and a huge crush on Rin. When Rin was seemingly killed in front of him, it shattered his world. He thought that the ninja world was full of pain and betrayal. This led him to be influenced by Madara. He became one of the main antagonists, all because of his love for Rin and the unbearable pain of losing her. His journey from a hopeful young ninja to a vengeful villain is a tragic consequence of Rin's death.
