To avoid making Naruto's suicide seem forced, the fanfic writer should first establish a deep emotional connection between Sasuke and Naruto. Show their relationship evolving over time. Then, when Sasuke cheats, it should be a major blow. But also give Naruto other things to live for. For example, his relationships with other friends like Iruka - sensei or his determination to protect the village. Maybe Naruto could initially think about suicide, but then have an epiphany about his other important values.
One way is to show Naruto's growth and development outside of his relationship with Sasuke. If he has other goals, like training to become a better ninja for the sake of the village or to help his friends in need. When Sasuke cheats, it will still be a shock, but his other aspects of life can act as a buffer. He could also have new friendships or interests that he discovers during this difficult time. This way, his potential thoughts of suicide would be more of a passing dark moment rather than a forced plot device.
I'm not sure if there is such a specific fanfic. Fanfiction can cover a wide range of scenarios, but cheating themes might not be very common in the Naruto fanfic world, especially considering the strong bond between Sasuke and Naruto. However, with the vast amount of fanfiction out there, it's possible that one exists.
In such a fanfic, Naruto might first feel extreme betrayal. He has always considered Sasuke a close friend or more. If Sasuke cheats on him, he could feel that his world has crumbled. He might initially go into a state of shock, unable to believe what has happened. Then, the thought of suicide could creep in as he might feel that there is no one left to trust or that his life has lost its meaning without Sasuke's loyalty. However, Naruto is also a strong - willed character, so he could also choose to rise above it and prove to Sasuke and himself that he doesn't need such a person in his life.
They might stumble upon a hidden village with a unique culture and way of life. This could lead to them learning new values and bringing those ideas back to their own village in the future. They could also meet new characters who become their allies or mentors along the way.
Naruto's reaction would be complex. He would be devastated because his bond with Sasuke is so deep. However, he also trusts Sasuke to an extent. So, he would be torn between his immediate emotional response of anger and his long - standing faith in Sasuke. He might start to look for clues and evidence, and in the process, he could end up uncovering Kabuto's devious plan while also reaffirming his friendship with Sasuke. He would probably be more determined than ever to set things right and prove Sasuke's innocence if he is indeed innocent.
At first, it would be really awkward. Naruto might be all over the place, trying to make the best of the situation, while Sasuke would be cold and distant. But as time passes, they would start to communicate more. Naruto's positive attitude might slowly break down Sasuke's walls. They could start training together again, like old times, but with a new layer of closeness. Eventually, they might develop a deep respect and love for each other that goes beyond friendship.
Secondly, use the existing Naruto universe lore. Incorporate elements like the ninja villages, jutsus, and missions. Let Naruto and Sakura's relationship grow within these contexts. For instance, during a dangerous mission, they could rely on each other's skills. Naruto's combat abilities and Sakura's medical skills could be the basis for their bond, rather than forcing a romantic or other unnatural connection.
Well, one possible plot could be that due to some political or clan reasons in the ninja world, Naruto is forced into a marriage with Sasuke. Maybe there's a threat from an outside force that can only be averted if the two most powerful ninjas, Naruto and Sasuke, are united through marriage. Naruto might initially be resistant as he values his friendship with Sasuke in a different way, but gradually realizes that this union could also bring about a new era of peace and understanding between their respective clans.
There might be some fanfics out there with such a plot, but it's not a positive or common representation of the Naruto characters. In the Naruto series, Hinata has always admired Naruto from afar and they end up together. Sasuke has his own story arc that is mainly focused on his revenge and redemption. Changing their relationships in such a way in a fanfic seems like a distortion of the original story's essence.
One way it could be developed is through extreme despair. Maybe Naruto fails to protect the village from a new and overwhelming threat. He blames himself so much that he starts to think his death would be a solution. For example, if all his friends were killed in the battle and he felt powerless to stop it, he might sink into deep depression and consider suicide as a way to end his pain.
The plot could start with Naruto accidentally stumbling upon the EMS. Then, as he tries to figure out how to use it, he attracts the attention of various ninja clans who either want to steal it or help him. This creates a lot of conflict and action.
