The main character of Flower City's Strongest Divine Doctor was betrayed by his girlfriend before he transmigrated. I would like to recommend a novel similar to this book,"My Broken Goldfinger". The story is also very interesting. I hope you like this fairy's recommendation. Muah ~😗

One possible scenario could be that Naruto's girlfriend betrays him because she is jealous of his godlike powers. Maybe she feels overshadowed and in a moment of weakness, she aligns herself with Naruto's enemies. It could lead to a great internal conflict for Naruto, having to face not only external threats but also the pain of betrayal from someone he loved.
One idea could be that the girlfriend, perhaps under the influence of an enemy, reveals Naruto's bloodline secrets to those who would use it against him. For example, she might be tricked into thinking she's helping Naruto in some way, but actually endangering him.
He could then feel a deep sense of anger. Naruto has a temper, especially when it comes to those he loves. He might vow to find out the reason for the betrayal and make things right, or if it was truly malicious, seek revenge in his own Naruto - like way, which would involve trying to understand the person's motives even while being angry.
One possible reason could be that she was forced to betray him. Maybe an enemy got to her family and threatened her to turn on Naruto. For example, in the Naruto universe, there are many powerful villains who would stoop to such tactics.
The story could explore how Naruto's power is affected by this betrayal. Maybe his godlike powers start to waver because his emotional state is so unstable. He might have to go on a journey to regain his confidence and control over his powers. Along the way, he could meet new characters who help him understand that not all relationships are doomed to end in betrayal. This would be a great way to develop Naruto's character further in the fanfiction.
The main character of "Snow Shocking the City", Bai Nuo Cheng's betraying girlfriend, was called Xiao Yu. This was a wuxia fantasy novel. I hope you like this fairy's recommendation. Muah ~😗
One reason could be jealousy. Maybe Naruto's success as a ninja makes his girlfriend jealous and she betrays him out of spite. Another reason might be that she is forced to by an enemy. For example, if she is blackmailed into betraying Naruto to save her family.
Naruto might initially be in shock. He's a very loyal person, so he wouldn't expect such a betrayal. He could try to talk to her to understand why she did it. For example, he might say something like 'Why? I thought we were in this together.'
He recommended the book," Top Student's UP Master Training Plan," a light novel written by Moonlight. It was about how a top student couple relied on each other to grow up and showed off their affection for each other daily. The male lead and female lead were 18 years old and had strong independence from a single-parent family. It was reasonable for them to be together at the beginning. With the help of the system, the male protagonist lived with the female protagonist after he became the protagonist. His daily life was calm and warm, and his literary works were not bad. Those who liked daily sweet works could read them. The Scumbag Detection System was not bad either. It was a science fiction novel written by Jing Ling. The female protagonist had a scumbag detection system, and punishing scumbags was very satisfying. The plot was compact, dark but thought-provoking. There were all kinds of scumbags in the story. The female lead was both good and evil. There was no CP and the ending was unexpected. " My Boyfriend Is A Little Weird " was a sci-fi post-apocalyptic novel by Natsuya Tingyu. Momo's boyfriend had become very strange. His background was the apocalypse of the planet's evolution. Although it was a post-apocalyptic novel, it was not bloody and had good logic. " My House of Everything Begins from Marvel," a novel written by Demonic Priest Sun Bu 'er. Xu Ce transmigrated to inherit the House of Everything and took orders in the Marvel World. It was Dong Xiaobai's fantasy romance novel. The male lead quickly dressed up as a scumbag. His angle was novel and his writing was good. The male lead was great, but some people felt that the story was boring. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The main character of this novel was a thousand-handed leaf bearer. He was the second generation of Naruto's son. The novel described his growth as a native of Naruto, as well as the process of fighting against the transmigrators of the other world as the "defender" of the Naruto world.
