They could be saying it because they want to set boundaries. If someone is constantly talking about their love affair fanfic, it can be annoying. So this is a way to say 'stop involving us in it'.
Basically, it's like saying we're not interested in or part of your made - up love story. Fanfics are often written by fans about fictional characters or relationships. So, this statement is a way of drawing a line and saying that this particular love - affair - centered fanfic has nothing to do with them. They might be tired of the excessive focus on such fictional romances or just not into that kind of thing at all.
Perhaps they are part of a group or community that is planning to have a big focus on fanfiction starting tomorrow. It could be for a reading challenge, a writing event, or just a general celebration of fanfiction. So they are saying 'tomorrow we love fanfiction' as a way of getting everyone pumped up for it.
Someone might say 'no reading fanfic' because they are focused on the original source material. Fanfic can deviate a lot from the original, and they might not want to risk getting a distorted view of the story they love. Also, they could be concerned about the legality or ethics of some fanfic, especially if it seems to be misusing the original work's concepts.
They might say it if they were really disappointed with the fan fiction. Maybe they had high hopes for it based on the premise or the fandom it was related to, but it turned out to be a huge let - down.
They could be saying it to encourage people to take control of their love lives. In many religious teachings, while God gives guidance, we are still expected to make our own choices. So, in the context of love, it's a reminder that we are the ones who should be writing our own love stories, not waiting for a divine intervention.
They might have read a bunch of crossover fanfics that were just really bad. For example, the plot didn't make sense or the characters' personalities were all wrong.
Someone might say it if they think Naruto has evolved into something more than just a ninja - based story. For example, it has complex character relationships that are not just about ninja battles.
Maybe because Naruto has a large and diverse world - building. It's not just about the Uzumaki. There are other important clans like the Uchiha too.
Maybe they believe that we are in control of our own destinies when it comes to love. So they say this to encourage people to be proactive in finding love.
Maybe it's something that could cause trouble if shared in the story. Like if it's a trade secret.
