Well, Harry could initially feel a sense of betrayal. He might think that Drao has been hiding this important aspect of himself all along. But then, he might also feel a bit of pity or a strong urge to help Drao if being imperisoued is something that Drao doesn't want or if it puts Drao in danger. Harry is a character who often tries to do the right thing, so he would probably start investigating how to reverse the situation.
The plot could develop with Harry trying to find a way to break the imperisoued state. He might search for ancient spells or consult with wise wizards like Dumbledore (if he's still around in the fanfiction).
Harry Potter might be a bit surprised. He'd probably think it's strange that people are writing about his friends' and his own relationships in such a different way. Hermione would likely be very interested in the writing style and how the authors are creating these new relationships. She might even take notes to improve her own writing. Ron would just laugh it off most of the time. He'd find it a bit odd but also funny.
Well, Ron could get angry. He has a strong loyalty to Harry, and seeing Harry with Draco, who he has always seen as an enemy, might make him feel betrayed. He might immediately jump to conclusions and start shouting or demanding an explanation from Harry.
The other students could have a range of reactions. Some might be sympathetic and try to befriend Harry more. Others might be afraid, especially if the abuser is still around. But overall, it would create a stir in the wizarding community, and there would be a general outpouring of concern for Harry's well - being.
In this kind of fanfiction, friends like Hermione and Ron might be overjoyed. Hermione would probably start planning things immediately, like the wedding ceremony details. Ron, on the other hand, might make some teasing remarks to Harry at first but then offer his sincere congratulations.
Well, in such a fanfiction, one possible reaction could be shock from their friends and family. They might not expect such a situation considering the relationship dynamics in the original context. For example, Hermione might be completely flabbergasted and struggle to come to terms with it.
Well, he might be really confused at first. Supernatural has all these different monsters and a very different magic system compared to his world. He'd probably be intrigued by the way the Winchester brothers deal with things though.
Luna would be very open - minded. She might see the fanfiction as just another form of magical thinking. She could find the wild and imaginative ideas in the fanfictions quite endearing and might even start to incorporate some of the concepts into her own unique view of the wizarding world.
They might be surprised. Harry is like a successor to them in a way, and seeing his relationship with Ginny in fanfiction could be unexpected for them. They could also be amused, thinking about how things have turned out in this fictional portrayal.
Hermione would probably be shocked at first. But then she would try to find a way to help Harry through it, using her vast knowledge of magic to figure out what's going on.
