A lot of these fanfictions have the theme of sacrifice. For example, Sasuke might have to sacrifice his vampire nature or Sakura might sacrifice her normal life to be with the other. Also, there's often the theme of redemption. If Sasuke has done bad things as a vampire, he may seek redemption through Sakura. And of course, there's the overarching theme of love and how it can overcome differences and obstacles, like the fact that one is a vampire and the other is human.
Love triangles are also a theme, though not always in a traditional sense. Sometimes it's more about the deep, platonic love they have for each other, but the dynamics can be similar to a love triangle as they all have strong bonds with one another. For example, Naruto and Sasuke's bond is different from Naruto and Sakura's, and Sasuke and Sakura also have their own unique connection. These complex relationships are often explored in 'naruto x sasuke x sakura fanfiction'.
Love triangles are also quite common. The complex feelings between Naruto, Sakura, and Sasuke can create interesting love triangle situations. And sacrifice is another theme. They are often willing to sacrifice for each other in these fanfictions, showing the depth of their bond.
Love and redemption are common themes. Sasuke has a troubled past, and often in these fanfictions, Sakura's love is what helps him find redemption. For example, in many stories, Sasuke realizes the error of his ways because of Sakura's unwavering love for him.
One common theme is family. Many fanfictions explore how Sakura and Sasuke start a family, deal with raising children, and pass on their values. For instance, in some stories, they have a child with special abilities and have to guide them.
One of the main themes is the struggle of expressing emotions. Sasuke, being his reserved self, often has a hard time showing his feelings for Sakura, and this creates a lot of tension and drama in the stories. Also, high school events like proms and sports competitions are common settings, which add to the theme of youth and coming - of - age.
One common theme is the adjustment to married life. They both have to adapt to living together, sharing their lives, and dealing with each other's quirks. For example, Sasuke's aloof nature might sometimes clash with Sakura's more outgoing personality, but they work through it.
One common theme is the struggle between love and power. Since Itachi is a vampire, he often has to balance his newfound power with his love for Sasuke. Another theme is the idea of forbidden love, as their relationship might be seen as taboo in the context of vampire and human (or in this case, another Uchiha).
One more theme is the co - existence of two different worlds. Sasuke's vampire world with its own rules and Sakura's human world. Fanfics usually show how they try to find a balance between these two worlds while being in love. They might face opposition from both sides, but they strive to be together regardless.
Common themes could include the development of their relationship from a hesitant start to a more intense and loving one. In a 'hot lemon' fanfiction, there might be more emphasis on their private moments, how they deal with their emotions in a more intimate context. For example, it could show how Sasuke, who is usually reserved, opens up to Sakura in a more passionate way. And Sakura, who has always loved Sasuke, might be shown as more confident in expressing her desires. Also, the fanfiction might play with the idea of them overcoming obstacles in their relationship through their new - found passion.
One common theme is the growth of their relationship. The pregnancy often forces Sasuke to open up more emotionally. Another theme is the anticipation of the baby's arrival. It includes things like preparing the nursery.
