Love is a very common theme. The idea of Sakura and the werewolf falling in love despite their differences. Another theme is acceptance, as they have to accept each other's nature, Sakura being human - like and the werewolf having his animalistic side.
Growth is a big theme. Both Sasuke and Sakura grow as individuals and as a couple in these fanfictions. For example, Sakura might become more confident in her abilities because of Sasuke's belief in her. Also, the theme of family is often there. They might start a family together, and how they raise their children and pass on their values is explored. And of course, there's the theme of loyalty. Their loyalty to each other and to their village is often tested and reaffirmed in these stories.
Well, I'm not sure about the exact title of all such fanfictions, but generally in these stories, Sakura often has some sort of special power or trait that attracts the werewolf. For example, in some, Sakura can communicate with nature, which is something that the werewolf respects and is drawn to. And then the plot usually revolves around how they overcome challenges together, like dealing with other supernatural beings who oppose their union or trying to find a place in a world that doesn't fully accept their relationship.
In a 'Sakura and Sasuke mate with Naruto' fanfiction, the plot might revolve around a post - war scenario. The ninja world is in a state of rebuilding, and Naruto, Sakura, and Sasuke are at the forefront of this effort. During this time, they realize that the traditional relationships and boundaries don't really matter as much as they thought. Sakura starts to see Naruto in a new light, and Sasuke, who has changed a great deal, also begins to feel a strong connection to Naruto. Their interactions could be filled with emotional exchanges, shared goals, and a sense of unity that goes beyond normal friendship, which could be interpreted as a form of'mating' in the context of this fan - created story.
I've heard of 'The Promise Kept'. In this fanfiction, Sasuke and Sakura's relationship is portrayed in a very realistic way. It shows their arguments, their make - ups, and how they slowly but surely fall more in love with each other. There's also 'Cherished Bond' which highlights the importance of their bond in the context of the whole Naruto universe, with their friends and family also playing important roles in their relationship.
Naruto would likely become more confident in his relationships. He has always been a bit insecure about his place with Sakura and Sasuke. In this fanfiction, he might finally feel like he truly belongs with them. Sakura could develop into a more understanding and inclusive character. She would have to learn to accept and embrace this new dynamic with both Naruto and Sasuke. Sasuke, on the other hand, would probably soften up a lot more. His cold exterior would melt as he becomes part of this unique relationship, learning to trust and rely on Naruto and Sakura in ways he never thought possible.
One popular fanfiction in this theme might be 'The Werewolf Bond'. It beautifully portrays Sasuke and Sakura's relationship in a werewolf - centered world. The story focuses on how they discover their werewolf mateship and the challenges they face together.
Perhaps there is an ancient evil entity that feeds on the hatred between werewolves and vampires. It doesn't want Sasuke and Sakura to succeed in bringing peace. So it uses its dark magic to create misunderstandings and conflicts between the two, trying to keep them at odds and prevent any chance of unity.
One plot idea could be that Sasuke is a werewolf and Sakura is a vampire. They are from rival clans but fall in love. Their love has to overcome the prejudice and enmity between their kinds. For example, they might have to hide their relationship from their respective families and communities who would be against it.
