It could mean that the person is saying goodbye to writing or reading Naruto fanfiction. Maybe they've lost interest in the Naruto fandom, or perhaps they're moving on to other forms of writing or hobbies.
It could mean leaving behind the idea of goodbye within the context of a web novel. Maybe it's about a character in the web novel who is finally free from having to say goodbye all the time, or it could be a thematic statement about the web novel itself moving away from sad partings as a major theme.
It could mean that someone views the 'Naruto' story as having elements that are characteristic of fan - created fiction. Maybe they think some parts of the plot or characters seem like they could be the result of fan creativity rather than strictly original creation.
It could mean the end of a romantic relationship. Maybe a couple has broken up and their love story has come to an end.
The meaning of saying goodbye to an old friend was farewell. In Li Bai's " Yellow Crane Tower Seeing Meng Haoran Off to Guangling ", the old friend referred to Meng Haoran, while Xi Ci referred to parting. This poem described the scene of Li Bai bidding farewell to Meng Haoran at the Yellow Crane Tower and Meng Haoran heading to Yangzhou. The Yellow Crane Tower was located in Wuchang, while Yangzhou was located to the east of the Yellow Crane Tower. Therefore, Xi Ci referred to the departure from the Yellow Crane Tower to the east. The reason why Li Bai chose to use western words instead of going east was because he paid attention to the artistic conception and allusions of the poem. The Yellow Crane Tower was a place where the literati of the Tang Dynasty liked to gather. Many poets mentioned the Yellow Crane Tower in their works. Among them, Cui Hao's Yellow Crane Tower was a classic poem that had been passed down through the ages. Li Bai used the word Xi Ci to add to the artistic conception and mystery of the poem.
Well, 'goodbye' is a simple parting word. 'Isekai' refers to the genre where characters are sent to a different world, and 'tensei' often means reincarnation in these stories.

It might be that they've read too many and found them too formulaic or they just have a change in their reading preferences.
It could mean that someone is ending a romantic relationship or a period of time filled with love. Maybe they have had a relationship that has come to an end, and they are saying farewell to all the memories, experiences, and emotions associated with that love story.
It could mean that Naruto, the character from the Naruto series, is singing something related to fan - created fiction (fanfic). Maybe in a creative fan - made scenario, Naruto has been given the ability to sing and is performing a song inspired by fan - written stories.
A 'fanfic' is a fan - created fiction. When it says 'naruto is a sadist fanfic', it could mean that in this particular fan - written story, there are cruel or sadistic behaviors or scenarios involving Naruto characters. But this is a deviation from the positive and inspiring Naruto we know, which is mainly about ninjas with good values.
Well, 'naruto is broken fanfic' might refer to a fanfic where the Naruto character or the world of Naruto is depicted in a way that seems out of place or not in line with the original. For example, if Naruto suddenly has some new power that makes him unbeatable without any proper build - up in the fanfic, it can be considered 'broken'. It could also be about the fanfic's overall plot being so messed up that it ruins the essence of Naruto.
Well, 'naruto' is a popular anime. A'sadistic fanfic' about it might refer to fan - created stories that involve cruel or unkind elements related to the Naruto universe. Maybe it's about characters being in overly harsh or violent situations that deviate from the original's more positive themes.
