One common theme is Sakura's growth as a character. Many fanfictions focus on her evolving from her initial self in the Naruto series. Another theme is her relationships, like her friendship with Naruto and Sasuke, and how they develop further.
Well, perhaps in this fanfiction, Naruto being adopted by the Haruno family gives him a different social standing in the village.

Well, a frequently seen theme is the exploration of their individual powers. Sakura's medical ninjutsu and Naruto's various ninja techniques are often developed further in fanfictions.

His development might involve him learning from the Haruno family's work ethic. If they are into things like medicine or other civilian professions, Naruto could gain an interest in those areas too. He could also become more protective of his new family, and this new sense of responsibility could shape his character.
