Often, in such fanfictions, a plot device is the 'arranged marriage' concept. Even if it's not in the Naruto -verse originally, writers might introduce it to bring Sasuke and Hinata closer. Also, the 'damsel in distress' situation can be used, where Hinata gets into trouble and Sasuke realizes his feelings as he saves her. And there's the 'shared secret' device, like they both know something about the Hidden Leaf Village that no one else does and that bonds them.
There are several common plot devices in this type of fanfiction. The 'accidental encounter' is a popular one. Maybe they meet in a forest while Sasuke is training and Hinata is collecting herbs. This unexpected meeting can start the spark of their relationship. Another device is the 'character transformation'. For instance, Sasuke becomes more open and gentle because of Hinata, or Hinata becomes more confident due to Sasuke's presence. Additionally, the 'external threat' plot device is used. A new enemy emerges that forces Sasuke and Hinata to work together and in the process, their feelings for each other grow.
One common plot device is the 'forced proximity'. For example, they might be on a mission together where they have to rely on each other. Another is the 'healing factor', where Hinata helps Sasuke deal with his inner demons. Maybe she uses her kind heart to make him see a different side of life.
One common plot device is the slow - burn relationship. They start as friends or comrades and gradually develop feelings over time. Another is the use of a common enemy or a difficult mission that brings them closer. For example, they might have to team up against a powerful new villain and in the process, realize their feelings for each other.
One common plot device is Sakura setting up 'accidental' meetings. For example, she might make it seem like Naruto and Hinata just happen to be at the same place at the same time, like at a local festival. This gives them an opportunity to interact without it feeling too forced.
One common plot device is the love triangle. It creates drama as Sakura may be jealous of Hinata's relationship with Naruto. Another is the redemption arc for Naruto's feelings. Maybe he used to be confused about his feelings for Sakura but then realizes his true love is Hinata. And there could be a friendship break - up plot device where Naruto distances himself from Sakura due to his newfound love for Hinata.
In many such fanfictions, the power struggle plot device is used. If Sakura becomes too powerful or tries to assert her dominance in a way that overshadows Naruto and Hinata's relationship or their own achievements, they might start to hate her. For example, if Sakura gets a high - ranking position in the village and starts making decisions that affect Naruto and Hinata negatively, it can fuel their dislike. Another aspect is the character arc plot device. The writer might give Sakura a negative character arc where she becomes more self - centered or greedy, which would make Naruto and Hinata dislike her.
A typical plot device could be the influence of an outside force. Say, a kind wizard or witch comes to the Dursleys and makes them understand the importance of Harry and his magic, and then they start to love him. Also, it could be that Harry himself shows extraordinary kindness towards the Dursleys in a difficult situation, which melts their cold hearts and changes their attitude towards him.
One common plot device is the 'what - if' scenario. For example, what if Hermione had been the one to save Harry from the Dementors instead of his father's Patronus? This can lead to a deeper emotional connection between them. Another is the 'arranged - relationship' plot, where they are forced to pretend to be in a relationship for some magical reason, but end up falling in love for real. Also, the 'jealousy' plot device, where they get jealous of each other's relationships with other characters and realize their true feelings.
Often, there's the theme of the unexpected. Since Sasuke was mainly associated with Sakura in the original story, the idea of him falling for Hinata is unexpected. Also, the theme of self - discovery is present. As Sasuke falls for Hinata, he discovers new aspects of himself and his ability to love and be loved. There may also be themes related to family acceptance, as they come from different clans.
One common plot device is the redemption arc. Narcissa may be portrayed as turning away from the dark side, and Harry, seeing this change, is drawn to her. Another is the protection plot, like Narcissa protecting Harry for some reason, which then leads to a bond between them. And sometimes, there's a magical bond or curse that forces them to interact and eventually fall in love.
A common plot point could be the jealousy factor. Other characters might be interested in either Sasuke or the female Naruto, which creates tension. There could also be a plot where they have to hide their relationship from the village or certain people. This secrecy adds an element of mystery and danger. Additionally, the fanfiction might explore how their relationship affects the overall balance of power in the ninja world. Since both are powerful ninjas, their union could have political and strategic implications.
One common theme is the struggle with their identities. Since they both have strong ninja identities, falling in love adds another layer of complexity. Another is the idea of redemption, as Sasuke might see Naruto as his path to redemption and love grows from there.
