I really like 'Sirius and Hermione: A New Chapter'. In this fanfic, their relationship starts off rocky as they have to overcome their initial differences.

I really like a fanfic called 'Sibling Secrets'. It shows how Hermione and Sirius interact when they find out they're siblings.

Well, there's 'The Unlikely Attraction' which delves deep into this concept. In this fanfic, Sirius Black's flirting with Hermione isn't just some light - hearted banter. It's part of a complex plot where their relationship develops over time, with Hermione initially being taken aback but then gradually growing interested as Sirius reveals more of his true self.

The author does a great job of building up their relationship gradually, with Hermione helping Sirius heal from his past traumas and Sirius in turn protecting Hermione from the darker forces in the wizarding world.
