Well, in an Anbu Naruto and Hinata fanfiction, their relationship could start to develop when Naruto realizes how Hinata has changed since joining the Anbu. She might be more confident and capable. Naruto, being the person he is, would be attracted to this new side of her. At the same time, Hinata could be more open with Naruto in the Anbu environment, which is more about comradeship and trust. They could start to share their thoughts and feelings more freely, and as they go through difficult missions together, their relationship could gradually shift from friendship to something more romantic.

As they face challenges side by side, their mutual respect and admiration could turn into love. Also, the fact that they are both part of the Anbu could give them a sense of belonging together, away from the prying eyes of the village sometimes.
Their relationship could develop as they are paired on dangerous Anbu missions. They would rely on each other for survival, which would deepen their bond. For example, Naruto might start to see Hinata in a new light when she saves his life during a mission.
In this type of fanfiction, their relationship could develop through shared classes. For example, they might be paired for a project in a ninja skills class. Naruto, with his determination, could inspire Hinata to be more assertive. And Hinata's kindness would draw Naruto closer to her.

Their relationship would likely grow stronger. As teachers, they would support each other. Naruto might rely on Hinata's calmness when dealing with difficult students. For instance, if a student is being rebellious, Hinata could use her empathetic nature to understand the root of the problem, and Naruto would back her up. This mutual support would deepen their bond.
Their relationship can develop as they rely on each other during training. For example, Naruto might start to see Hinata in a new light when she saves him from a tricky training situation using her skills. This newfound respect can be the start of deeper feelings.

Naruto and Hinata's relationship might grow as they face challenges together during the pregnancy. Maybe there are financial concerns or family issues that they need to deal with. As they work through these problems hand in hand, their love for each other and their commitment to their future family will strengthen. For instance, if Naruto's work as a ninja doesn't pay enough for all the baby expenses, they might have to figure out a side hustle together, and this shared experience can make their relationship even stronger.
Their relationship might become more of a strategic partnership. Naruto would respect Kurama's power and knowledge more deeply as they face the complex and dangerous ANBU missions together.
Their relationship could become more competitive. Since ANBU is a place for elite ninjas, they might constantly strive to outdo each other in missions.
