Well, in some versions, Snape might use his magic skills and authority within Hogwarts. He could place protective spells around Hermione or keep a watchful eye on her movements, ensuring Draco can't get close to her without his knowledge.
One common theme is the redemption of Snape. Hermione might see a side of Snape that others don't and try to protect him from false accusations or danger, highlighting his more complex and misunderstood nature.
One possible reason could be that Snape, despite his enmity with Sirius, has a sense of duty towards Hermione as a student at Hogwarts. He might not want to see any harm come to her, even if it means protecting her from Sirius. Another reason could be that Snape has his own complex motives and perhaps sees Hermione as an important asset to the wizarding world, so he steps in to keep her safe.
In the wizarding community at large, he could become an outcast. Other wizards and witches would likely look down on him, and he might find it difficult to get support or make alliances in the future. His actions could also lead to him being targeted by those who support Hermione and want justice for her.
