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.
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.
Snape would probably be very stern with Draco. He might give him a severe scolding and deduct points from Slytherin. Snape is a strict teacher and he won't tolerate such behavior from his own house students.
There should not be any form of fanfiction promoting such a heinous act. The 'Harry Potter' universe is about magic, friendship, and good versus evil. These values are completely violated by the concept of rape. It is unacceptable to create or promote content that involves non - consensual and violent acts between characters.
A theme of friendship is also great. Hermione could be the one to break through Snape's cold exterior and they become unlikely friends. They could exchange books, discuss magical theories, and help each other grow. Also, a theme of them being part of a team in a magical competition can be interesting. They would have to rely on each other's strengths to succeed.
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.
Well, it could be that Draco, in his pure - blood pride and influenced by his family's views, targets Hermione. Maybe he uses some dark magic or just plain bullying. Snape, despite his often cold exterior, might save her because he secretly admires Hermione's intelligence or perhaps he has a deeper reason related to his own past with the Gryffindors or his hidden loyalties. For example, he could see a bit of himself in Hermione's determination to succeed in a world that is often against her.
One possible reason could be that Draco has had a change of heart. Maybe he realizes that Hermione is a person worthy of protection regardless of her House or her friendship with Ron. He might have seen some injustice about to befall her from Ron and his Gryffindor bravado getting out of hand.
Well, perhaps Snape uses his position as a teacher to step in. He could have been observing the situation secretly and when Draco was about to do something harmful to Hermione, Snape intervened with a firm command or some magic spell to stop Draco in his tracks.
