Perhaps in the fanfic, new characters are introduced that have a stronger connection with Naruto. These characters might share similar past traumas or have a more exciting chemistry with him. For example, a character who also has a demon sealed inside them could bond with Naruto on a different level compared to Sakura. And Sakura, being too hesitant or slow in expressing her true feelings, loses her chance.
One possible reason could be that Sakura was too focused on her own goals and neglected her relationship with Naruto. In some fanfics, she might be so driven by her medical ninja career or her need to prove herself that she doesn't give Naruto the attention he needs. Another reason could be that Naruto's own growth and experiences lead him to find someone else more compatible. Maybe he meets a character who understands his pain of being an outcast more deeply, and Sakura just doesn't fit into that new vision of his future.
In the fanfic, Sakura's personality might be portrayed in a way that makes her less appealing to Naruto. If she is written as overly jealous or possessive, it could push Naruto away. Naruto, who values freedom and friendship deeply, may not tolerate such behavior. Meanwhile, other characters around him could be shown as more supportive and positive, causing him to gradually lose interest in Sakura.
