One possible reason could be that Tsunade makes a decision regarding the village that Naruto strongly disagrees with. For example, if she refuses to send help to a neighboring village in need, Naruto, with his strong sense of justice, might get angry. He's always been about protecting and helping others.
There could be. Fanfiction writers often come up with all sorts of interesting and unexpected relationships in their works. Given that both Naruto and Tsunade are important characters in the Naruto universe, a writer might have decided to create a story where Naruto is Tsunade's grandchild to explore new storylines, character development, and the impact on the existing Naruto world. It would likely involve a lot of creativity in terms of how their relationship affects the plot, the other characters, and the overarching themes of the Naruto story.
If Tsunade kisses Naruto, it could strengthen their relationship in a mentor - like way. Naruto might see it as a sign of deep respect and trust from Tsunade. He would likely feel more confident in following her guidance. For Tsunade, it could be a way of showing her pride in Naruto's growth.
Maybe Jiraiya found out some dark secret about Naruto's past, like his connection to the Nine - Tails, and decided to keep it from Naruto. When Naruto eventually discovers this, he would be angry at Jiraiya for not trusting him enough to share the truth. This could lead to a rift between them in the fanfiction.
Another reason could be in a fan - created scenario where there are secrets involved. Hinata might be keeping a secret from Naruto that, when revealed, makes Naruto feel betrayed or deceived. This sense of betrayal could easily turn into anger. For instance, if Hinata has a connection to an enemy that she's been hiding from Naruto.
Naruto being angry at Kushina in fanfiction could stem from a feeling of abandonment. Even though she's his mother, if in the fanfiction she was absent during important moments in his life, whether physically or emotionally, Naruto could be angry. He might feel that she didn't fulfill her motherly duties. For instance, if she was more focused on other things like her own past traumas or relationships, and neglected Naruto's needs, that would surely make him angry.
Well, it could develop through shared experiences. For instance, if they both go on a diplomatic mission to another village. During the journey, they face difficulties like hostile ninja attacks or harsh weather. They have to rely on each other's skills. Naruto's combat skills and Tsunade's strategic thinking complement each other. This cooperation makes them closer and over time, love might bloom between them.
One possible reason could be a misunderstanding. Maybe Tsunade received some false information about Naruto that made her think he was a threat to the village, so she took actions that ended up hurting him.
Naruto might be initially confused. He trusts Tsunade, so being kidnapped by her would be completely unexpected. He would probably start by asking her why she's doing this.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
