Sakura's jealousy might manifest through her actions. For example, she could be cold towards Hinata when she sees Naruto and Hinata together. Maybe she makes snide remarks or tries to insert herself between them more often.
In the fanfiction, Sakura's jealousy may be quite complex. It could start with her being in denial about her feelings towards Naruto. When she sees Naruto and Hinata getting closer, she might initially act like she doesn't care. But then it could escalate to her being more irritable around them. She might start training extra hard not just for her own growth but also to prove to Naruto that she is better than Hinata in some ways. She may also try to find faults in Hinata's relationship with Naruto, all because she has unacknowledged feelings for Naruto herself.
Sakura's jealousy might show through her actions. She could try to separate Naruto and Ino. She might start inviting Naruto to do things alone more often, like training or going for a walk, just to keep him away from Ino. And when it comes to Ino, she might be less friendly than before, not sharing information or being standoffish.
The jealousy can create conflict. It might lead Hinata to act out of character, perhaps trying to compete with Sakura in ways she normally wouldn't. This can drive the plot forward as it adds a new dynamic to the relationships between the characters.
On the other hand, her jealousy could also be a driving force for her to improve herself. She might see Naruto's success and instead of just being jealous, use it as motivation to become stronger. This could lead to a more equal relationship in the long run, as she catches up to him in terms of skills and abilities.
Maybe it's because of Naruto. If Hinata has a closer relationship with Naruto than Sakura does in the fanfiction, Sakura could be jealous. After all, Sakura has her own feelings for Naruto.
Sakura's jealousy of Hinata can be portrayed in a more subtle way too. In some fanfictions, she might distance herself from Naruto when she sees Hinata getting closer to him. Instead of showing her jealousy outwardly, she'll withdraw and become more focused on her training or other friendships. But it's clear to the readers that she's jealous because of the way she'll steal glances at Naruto and Hinata when they're together, and the sad look in her eyes when she does so.
On the other hand, Hinata's jealousy is depicted much more delicately. Since she's shy, her jealousy might be shown through her sad looks or small gestures. For example, she might lower her head or have a moment of hesitation when she sees Naruto with another girl. Writers often use her body language to convey her jealousy rather than big, obvious outbursts.
One common reason could be Naruto's growing popularity and strength. As Naruto becomes more powerful and well - liked in the fanfiction, Sakura might feel overshadowed. Maybe she's jealous of the attention he gets from their peers or even from her own friends.
In many Naruto fanfictions, Sakura might be jealous of Hinata's relationship with Naruto. This could be because Sakura has her own unexpressed feelings for Naruto. For example, she may see Hinata's gentle and supportive nature towards Naruto and feel envious. It adds an interesting dynamic to the story as it can create tension between the characters.
Sakura's jealousy could also be shown through her internal thoughts. The writer could use a first - person perspective to let the readers know what's going on in Sakura's mind. She might constantly compare herself to Hinata and feel inadequate, especially when it comes to Sasuke. This internal struggle can add depth to her character in the fanfiction.
Often, Sakura's jealousy is shown through her reactions. She might glare at Hinata when she's with Naruto or make snide remarks. For instance, in some fanfictions, when Hinata gives Naruto a gift, Sakura might say something like 'He doesn't need that from you.'
