Love triangles can also be a theme. For example, there might be other characters who are interested in Sakura, but Itachi's possessiveness won't allow them to get close. This creates a lot of tension and drama in the story.
One common theme is protection. Itachi is often depicted as being extremely protective of Sakura, which is a form of possessiveness. He doesn't want her to get hurt, whether it's from physical threats or emotional harm.
The theme of mutual understanding also pops up a lot. Sakura, being a strong - willed and intelligent character, tries to understand Itachi's motives and actions. Itachi, in turn, begins to see Sakura in a new light, and they develop a deep connection based on this understanding that goes beyond the surface.
One possible scenario in such a fanfiction could be that Itachi, with his typically stoic nature, shows possessiveness in a very quiet and intense way. For example, he might always be around Sakura subtly protecting her from any potential threats. He may not openly show his feelings but his actions speak volumes. Sakura, on the other hand, could be initially confused by his possessive behavior but gradually come to understand it as a sign of his deep affection. In this type of fanfiction, the writer could explore how their relationship develops against the backdrop of the Naruto universe, perhaps with other characters reacting to their unusual bond.
One possible fanfiction could involve Itachi being possessive over Sakura in a way that is born out of his need to protect her. He might see her as a symbol of hope or something precious in a dark world. Maybe he secretly watches over her, using his skills to keep her out of harm's way without her knowledge at first.
Often, the theme of secrecy is involved. Itachi has his own secrets, and his possessiveness over Naruto could be related to keeping Naruto in the dark about certain things. This adds an element of mystery to the fanfiction. Also, the theme of growth is there. Naruto's growth as a character might be affected by Itachi's possessive presence, either positively or negatively.
Common themes in such fanfictions include the idea of ownership. It's not in a literal sense, but more of an emotional ownership. Sakura might feel that Sasuke is 'hers' after waiting for him for so long. And Sasuke might have a similar feeling towards Sakura. Another theme is the struggle with independence. Their possessiveness can sometimes clash with the other's need for independence. For example, Sasuke is a very independent character, but if Sakura is too possessive, it can create a conflict. Also, there's often the theme of redemption. Sasuke might be possessive as a way to redeem himself for all the pain he has caused Sakura in the past, by making sure he is the only one in her life now.
Love and devotion are also key themes. The possessiveness is really a manifestation of their deep love. In these fanfictions, their love is so intense that it turns into possessiveness. They are devoted to each other and the fanfiction might show how they handle situations where that devotion is tested, such as when they are separated or faced with difficult choices.
The theme of jealousy often appears. Gaara may become jealous if he sees Sakura interacting with other male characters, especially those who are also powerful or have a history with her. This jealousy can manifest in different ways, from silent brooding to more aggressive displays of his possessive nature.
One reason could be that he sees something special in Sakura. Maybe he admires her strength or her kind heart, and he doesn't want to lose her to someone else who might not appreciate her as much as he does.
One common theme is the exploration of forbidden love. Since Itachi is from a different clan and has his own complex past, and Sakura is associated with Team 7, their relationship is often seen as something that goes against the norms in the Naruto universe.
Another theme could be the challenges Sakura faces in her role as a secretary. For example, she might have to deal with Itachi's secrets or difficult clients. Also, the power imbalance in their relationship, as Itachi is likely in a higher position, can be an interesting theme to explore. There could be stories where Sakura has to assert herself in a male - dominated work environment.
