The main problem is that Sirius Black is from an older generation of wizards and has a very different set of values and experiences compared to Hermione. For example, Sirius was part of the Order of the Phoenix during the first wizarding war, while Hermione is dealing with the aftermath of the second wizarding war. Their perspectives on magic, society, and relationships are likely to be different. Moreover, Sirius has a rather dark past which might be hard to reconcile with Hermione's relatively sheltered Hogwarts life. It's a challenge to create a story where they can interact meaningfully without sacrificing the essence of either character.
There are several difficulties. Firstly, Sirius Black has a strong connection to the Marauders and his past with James Potter, which is quite different from Hermione's world. Secondly, his time in Azkaban has made him a rather broken and unpredictable character, and Hermione is someone who likes to have things in order. Thirdly, their relationship in the canon is not very developed, so when writing fanfiction, it's hard to build a believable relationship between them. Writers need to consider how to make their interactions seem natural, how to develop their relationship over time, and how to handle the differences in their personalities and backgrounds.
