Another way it could end is that Sakura distances herself from them for a while to deal with her jealousy. But after some soul - searching, she comes back and they all become closer friends. Sakura might find that her friendship with them is more important than any unrequited feelings she had.
The story could also end with Sakura finding a new love interest. This new relationship makes her see that she doesn't need to be jealous of Hinata and Naruto. She can have her own happily - ever - after, and she can look at their relationship with a new perspective, free from jealousy.
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.
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 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.
In such a fanfic, Sakura might start acting out of character. She could become more distant from Naruto and Hinata. Maybe she'd try to prove herself better than Hinata in front of Naruto, like showing off her ninja skills more often.
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.
Yes, in some fanfictions, Sakura can get jealous of Hinata. For example, if Hinata has a closer relationship with Naruto than Sakura does in the story, Sakura's feelings for Naruto might make her jealous. It could be because Hinata is always so supportive and kind towards Naruto, which Sakura may feel she lacks in comparison.
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.
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.
In the fanfiction, Naruto might start distancing himself from Hinata and Kiba. He could focus more on his training to distract himself from the jealousy.
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.
Perhaps Sakura is jealous because of her own insecurities. She might be comparing herself to both Naruto and Ino. Naruto has his own charm and strength, and Ino has her grace and popularity. Sakura, who might be struggling with her own self - worth, could see their interactions and feel envious, thinking that they are better off without her or that they have something she doesn't.
