One possible scenario in this fanfiction could be that Sakura realizes her long - hidden feelings for Naruto when she sees Hinata getting closer to him. She might start to act out in small ways, like being a bit more snippy with Hinata during team meetings or training sessions. However, she also has to deal with her own sense of pride and the fact that she once rejected Naruto.
In many Naruto fanfictions, Sakura can often be depicted as getting jealous quite a bit. She has strong feelings for Sasuke, and when she sees other girls getting close to him, it can trigger her jealousy. For example, in some fanfictions where a new girl character is introduced and shows interest in Sasuke, Sakura's jealous side comes out strongly.
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 a fanfiction scenario, Naruto being a jealous husband might lead to some internal conflict. He has always been confident, but when it comes to Hinata's affection, he might worry that he's not doing enough. So, when he sees Hinata having a normal conversation with someone else, he might start to doubt himself. This self - doubt can be explored in the story, and through his relationship with Hinata, he can learn to overcome it.
In the fanfiction, Sakura could be jealous because she has an ego. She might have thought that Naruto would always be there waiting for her. But when he falls for Hinata, it bruises her ego. Additionally, she may have seen Naruto as her safety net, someone who would always support her no matter what. Losing that special status to Hinata makes her envious and jealous.
It could end with Sakura fully accepting Hinata and Naruto's relationship. She realizes that her jealousy was unfounded and that she is happy for them. She might even become one of their biggest supporters.
Well, I'm not entirely sure. It depends on how popular this particular concept is among the fanfiction writers in that fandom. Some might find it an interesting dynamic to explore, so there could be some out there. You should also check out any dedicated Naruto fanfiction forums where people might recommend such stories.
In such a fanfiction, Hinata might be jealous of Sakura because Sakura could be more popular or confident. Maybe Sakura has skills that Hinata wishes she had, like better combat skills or more outspokenness. Also, if there's a love interest involved, and the guy seems to pay more attention to Sakura, it would make Hinata jealous.
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.
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.
