Well, first of all, it's disrespectful to the original story and the author. The Harry Potter books are about much more than that. Second, it can be very uncomfortable for the fans, especially those who grew up with the series. And finally, it may not be legal in some cases as it could be seen as misusing the intellectual property.
Some fans write these fanfictions because they believe Harry and Hermione have a special bond. In the original books, they are very close friends, and fans like to explore the idea of that friendship turning into something more. It gives them a chance to create their own version of the story where the two end up together.
Some fans like it because it offers an alternative to the canon relationships. It gives a chance to explore a different dynamic between Harry and Hermione, one that might be more romantic or at least a very deep friendship that's different from what's shown in the books. It allows for creativity and new storylines.
Hermione and Ron were very popular characters in Harry Potter because their interactions and friendship were very real and touching.
The reason Rowling wrote Hermione and Ron as a couple was probably to highlight the innocence and kindness between them. The relationship between them was not only a friendship between classmates, but also a deep emotional connection. They supported and encouraged each other. Hermione and Ron's personalities and interests complemented each other very well. They could understand and share each other's lives better together.
As for Zhang Qiu, her ending in Harry Potter was a mystery. In the whole novel, Zhang Qiu's image was very vague. Her existence and behavior were very unexpected. Some people thought that Zhang Qiu might be one of Harry Potter's parents, but Harry did not specifically mention her. Some people thought that Zhang Qiu was just a fictional character, and her existence was only to promote the development of the story. No matter what the truth was, Zhang Qiu's ending in the novel was very regrettable.
One major problem is that it violates the nature of their relationship in the original 'Harry Potter' series. Their relationship is based on friendship and mutual respect, not any kind of inappropriate or sexual undertones. This kind of fanfiction can be seen as disrespectful to the original work and its fans who cherish the pure relationship between the characters.
There are fanfictions that might explore different scenarios between Harry and Hermione, but the idea of them showering together is often not in line with the original spirit of the 'Harry Potter' series and can be seen as inappropriate by many. However, in the vast realm of fanfiction, there may be some out - there interpretations that try to handle it in a more platonic or comical way, but it's still a rather rare and controversial concept.
Another aspect is the emotional depth it can add. Hermione being petrified is a very emotional event in the series. Fanfiction writers can really dig into the feelings of the characters, especially Harry. They can create scenarios where Harry blames himself or where he becomes more protective of Hermione after she is cured, which can be really interesting for readers who want more emotional exploration.
One reason could be that in the original series, they are very close friends. Hermione might be possessive in fanfiction because she's protective of Harry. She's seen all he's been through and wants to keep him safe from harm, both physical and emotional, and this overprotectiveness can come across as possessiveness.
Another reason is that it offers a different take on the original story. It's a form of 'what - if' scenario. Fans get to explore a world where Harry and Hermione's relationship took a romantic turn and they had a big family. It gives more room for creativity, like creating new characters in the form of their children and new plotlines centered around family dynamics and the challenges of raising magical children.
Well, 'phantom menace' already is a 'Star Wars' story. It was Episode I of the prequel trilogy. It introduced important elements like the Trade Federation's blockade of Naboo, the discovery of Anakin Skywalker, and the return of the Sith. All these aspects are deeply rooted in the 'Star Wars' lore and were crucial for setting up the events that followed in the subsequent movies.
