There are some out there. However, the quality can vary greatly. Some might focus on a romantic obsession where Blaise is constantly pining for Hermione, while others could take a more platonic but still intense interest approach. It really depends on what you're into in terms of story themes and writing styles.
One common theme is the forbidden love aspect. Since they are from different houses in Hogwarts, there's often a sense of it being against the norm. Another theme could be Blaise's admiration for Hermione's intelligence, which might be the root of his obsession.
One possible fanfiction could involve Hermione and Blaise coming from different backgrounds in the wizarding world. Their relationship might start as an unexpected encounter. Maybe they are paired together for a special project at Hogwarts. As the story progresses, Hermione discovers she's pregnant. This could lead to a lot of drama as they face the reactions of their friends and families, who might be against their union due to the house rivalries. For example, Hermione's Gryffindor friends could initially be skeptical of her relationship with Slytherin Blaise.
Their parents could be main characters. Blaise's mother, who might be a proud Slytherin - influenced witch, and Hermione's parents, who are Muggles but have a unique connection to the wizarding world through Hermione. Their interactions could add a lot of depth to the story.

Another theme is the exploration of the wizarding world from their combined perspectives. Fanfictions often use their relationship as a means to show different aspects of magic, Hogwarts, or the wizarding society that might not be as easily explored through other characters. For example, they might go on adventures in less - known parts of the wizarding world.
One possible fanfiction could be about Blaise, Hermione and Draco all studying in the library.

This could lead to an unlikely friendship between the three of them.
