Hermione would probably be very angry. She is a strong advocate for fairness and the right way of doing things. So, she would likely confront Ginny about using such an unethical method on Harry.
Other characters in Hogwarts, like Neville, might be disappointed in Ginny. Neville, who has grown to be a brave and moral character, would see the use of love potions as a form of cheating. He might distance himself from Ginny, and this could lead to Ginny being ostracized by some of her peers. The general reaction from most of the morally upright characters would be negative, as using love potions violates the principles of trust and true love in the wizarding world.
Some characters might be completely shocked. For example, Ron, who was Harry's best friend, would probably be very confused and perhaps even a bit angry at first. Hermione, on the other hand, might try to be more understanding and look at the situation from a logical perspective. The wizarding community as a whole would likely be divided. Those who were close to Ginny would feel a sense of betrayal, while others might be more open - minded and see it as an unusual but possible development in this fictional scenario.
Well, if Ginny uses love potions on Harry in fanfiction, it might create chaos among their friends. Their friends, like Hermione, might sense that something is off with Harry's behavior and start investigating. This could lead to a big conflict within their friend group, as some might side with Ginny thinking she did it out of love, while others would be appalled by her using such unethical means.
Ron would probably be extremely confused and might make some awkward jokes at first. But once he sees that Harry is doing it for Ginny and that it's all in good fun, he would likely come around and support it. Hermione, on the other hand, would be more accepting from the start. She might even offer some advice on how to make the cross - dressing more believable, like using magic to adjust Harry's voice to be more feminine. The other Gryffindor students would likely have a range of reactions, from laughter and amusement to those who are a bit more conservative and might be a bit taken aback at first.
Dumbledore would probably be very calm and have a long - term plan. He might use this as an opportunity to teach Harry something new or guide him in a different direction. Some of the teachers at Hogwarts might be worried about how this will affect Harry's performance in class and his safety at school.
Some students might be shocked. For example, Ron would probably be open - mouthed in disbelief. Hermione might be initially scandalized but then try to analyze the situation rationally. The Slytherins could have a mix of reactions. Some might be disgusted as they don't expect Blaise to be involved with Harry. Others might see it as an opportunity to tease Blaise or get some leverage over Harry.
Ginny would likely be heartbroken. She's a strong character but she loves Harry deeply. She might start to question herself and what she did wrong. Cho, on the other hand, would be surprised but also happy. She may have still had feelings for Harry all along. Harry himself would be conflicted at first, feeling guilty for leaving Ginny but also excited about the possibility with Cho.
Ron would be furious. He would immediately start looking for Ginny and would probably want to confront Harry without thinking. Hermione, on the other hand, would be more rational. She would try to figure out why Harry would do such a thing and look for clues. The Weasley parents would be extremely worried and would likely reach out to all their contacts in the wizarding world for help.
The Weasley family would likely be overjoyed. Molly Weasley would probably start knitting baby clothes right away and fussing over Ginny. Arthur Weasley would be proud and offer all kinds of support, maybe even trying to build some new magical baby gadgets. As for Harry's side, since he doesn't really have much family left, his friends like Hagrid would be extremely happy. Hagrid might bring some special magical creatures to visit Ginny during her pregnancy, like a very gentle unicorn that is said to bring good luck to expecting mothers.
Hermione would likely be devastated. She might go into a deep state of mourning, but also use her intelligence to try and figure out what led to Harry's death. Ron would be angry and heartbroken at the same time. He'd probably want to seek revenge if there was someone or something responsible.
Their friends would be in shock. Ron, being Harry's best friend and Ginny's brother, would be torn between loyalty to both. Hermione would probably be disappointed in Ginny and very supportive of Harry. The Weasley family as a whole would be divided. Mrs. Weasley, who loves Harry like a son, would be heartbroken and angry at Ginny. Their other friends at Hogwarts or in the Order of the Phoenix would likely gossip and have mixed feelings. Some might pity Ginny for the difficult situation she got herself into, but also condemn her for cheating on Harry.
