I'm not sure specifically as I haven't read it in detail. But generally, it might be about a woman's journey to enhance or improve her husband in every possible way, perhaps in terms of his skills, personality, or social status.
I don't know for sure since I haven't read the novel, but I assume the main characters would be the wife who is on the mission of levelling up her husband and the husband himself.
Well, it depends on the context of the light novel. It could have cheats related to leveling up quickly in a game - like scenario within the novel. For example, finding a hidden item that multiplies experience points. Or perhaps cheats for getting rare items or unlocking secret areas. Without reading the novel, it's hard to say exactly what the cheats are.
The main reason why the protagonists in web novels usually had some cheats on was that it could bring more excitement and interest to the story.
Using a cheat could allow the protagonist to instantly gain great strength or skills to gain an advantage in battle. This advantage would allow the protagonist to defeat the enemy more easily and complete the mission faster.
Using a cheat could also allow the protagonist to gain more experience and knowledge, allowing him to grow and develop faster. This kind of growth and development could make the protagonist stronger, more charming, and more in line with the reader's expectations of the protagonist.
Of course, not all protagonists of web novels would use cheats. Some authors might let the protagonist grow through his own efforts and skills, which was also very popular. However, using cheats was still one of the common methods in web novels.
There might be. The Naruto fan community is vast and diverse. Fanfic writers sometimes like to create alternative storylines for various reasons. Maybe they want to explore different character dynamics or add some drama. But this kind of plot goes against the typical perception of Sakura's character in the original Naruto story.
In Sims 2 Life Stories, 'move_objects on' is a great cheat. It allows you to move any object, even if it's in the way or seems immovable. You can use this to create unique house layouts. Also, 'kaching' is a money - adding cheat. It gives your Sim 1000 Simoleons each time you enter it in the cheat console.
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.
I don't think there would be a lot of fanfiction like that. Hinata has always been loyal to Naruto. In the Naruto universe, their relationship is based on a lot of development and mutual understanding. So it's hard to imagine a scenario where Hinata would cheat on Naruto with Boruto in a legitimate fanfiction.
