If Draco steals Hermione from Ron in fanfiction, it might show a different side of Hermione. She might be attracted to Draco's intelligence in a different way than Ron's loyalty. This could lead to new magical adventures where Hermione uses her knowledge in a more Slytherin - like way, influenced by Draco. It could also make for some interesting interactions between the Gryffindors and Slytherins, as now there's a connection between them through Hermione. The story could explore how love can cross house boundaries in a more extreme way than what we see in the original books.
Ron would be furious. His best friend being 'stolen' by his former rival would make him feel a mix of anger, betrayal, and jealousy. Harry would probably be in a difficult position. He's friends with both Ron and Hermione, so he might try to mediate at first, but if Draco is being difficult, he'd side with Ron. Ginny would be protective of her brother and would likely be very critical of Hermione for choosing Draco. The Slytherins, on the other hand, might be initially shocked but then accept it as Draco asserting his power and getting something he wants.
Yes, there are some out there. Some fanfictions explore this alternative relationship dynamic in interesting ways. They might rewrite the story's events and character interactions to make it seem more plausible for Harry to be with Hermione instead of Ron.
The plot could start with Harry realizing he has deeper feelings for Hermione than just friendship. He might start spending more time with her, which causes tension between him and Ron. Eventually, he could confess his feelings to Hermione, and she might be conflicted because of her relationship with Ron.
Well, in some versions, Ron might use his quick wit and knowledge of Hogwarts' secret passages to outmaneuver Draco. He could lead Hermione to safety through a passage that Draco doesn't know about.
Well, it definitely makes things more complicated. Ron would probably be very confused and angry at first. He might see Draco's actions as a form of interference or even an insult. He may think Draco has some ulterior motives towards Hermione.
Draco might be motivated by jealousy. He could be jealous of Ron and Hermione's friendship or a possible romantic relationship between them. So he tries to harm Hermione out of spite.
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.
One possible motivation could be that Draco has changed. He might have seen the error of his ways and decided to do the right thing. Another motivation could be that he has feelings for Hermione, even if they are not fully realized yet. He doesn't want to see her in a bad situation, so he steps in.
A popular one is 'New Beginnings'. Here, the story focuses on how Hermione copes with Ron's betrayal and how Draco enters her life at that crucial moment. It shows a different side of the Hogwarts world and the characters, with their relationships evolving in unexpected ways.
