In some fanfictions, the curse mark can be a source of tension. If Sasuke's curse mark makes him more aggressive or unpredictable, Sakura might be worried about him. For example, he could accidentally lash out at her during a training session. This would put a strain on their relationship as she tries to help him and he tries to keep his distance to protect her from the curse mark's influence.
One great fanfiction could be where the curse mark on Sasuke or Sakura gives them unique powers that they have to learn to control. It might involve them training together to master these new abilities. For example, if Sakura has a curse mark that enhances her strength but also has a dark side, Sasuke could help her control it using his own experiences with the curse mark. This kind of fanfiction often explores their relationship in a deeper way, as they rely on each other more.
One possible plot could be that they get the curse marks from a new, powerful enemy. They then have to figure out how to control the curse marks together without losing themselves to the dark power. Maybe they go on a journey to find a way to remove the marks while also facing challenges from other villages who see them as a threat because of the marks.
In some fanfictions, the curse mark can initially drive a wedge between Naruto and Sasuke. Sasuke might become more withdrawn and brooding due to the power and dark influence of the curse mark. Naruto, on the other hand, would be worried about his friend but might not fully understand what Sasuke is going through. This could lead to some misunderstandings and arguments between them as Naruto tries to reach out while Sasuke pushes him away.

The curse mark could have a mind of its own. It starts to communicate with Naruto and Sasuke in their dreams, trying to manipulate them into doing its bidding. Naruto, being the optimistic one, tries to resist and turn the curse mark's power into something positive. Sasuke, however, is more tempted by the power it offers. This could lead to a rift between them as they have different approaches to dealing with the curse mark, and their relationship would be put to the test.
It could be the result of a dark wizard's experiment gone wrong. Maybe some dark wizard was trying to create a new form of dark magic, and Harry accidentally got caught in the crossfire and ended up with the curse mark.
Their friends might be initially afraid of them. Since the curse mark is often associated with dark power, friends like Sakura and Kakashi could be worried that Naruto and Sasuke might lose control. This could create some distance between them as their friends are not sure how to approach them anymore.
The plot could be less centered around Sasuke's struggle with the curse mark's power and Orochimaru. Maybe there would be more focus on his normal ninja training and missions with Team 7. For example, he could be more involved in regular village protection tasks instead of being preoccupied with the curse mark.
Well, in many cases, characters would face a lot of discrimination. However, some strong - willed characters in Harry Potter curse mark fanfiction might try to educate others about the mark. They would explain that just because they have the mark doesn't mean they are evil. They could give examples of how they are still the same person with the same values and loyalties. They might also try to find a cure or a way to control the mark's effects to prove to others that they are not a threat.
