Well, the original story focuses mainly on the big adventures, like fighting Voldemort and saving the wizarding world. But the lemon fanfiction is more about the romantic and sexual side of Hermione and Ron's relationship, which was only hinted at in the original. For example, in the books we just see them getting together at the end, but in the fanfiction we can see all the details of their intimate moments.
The original story is written for a general audience and has to adhere to certain standards. Fanfiction, especially the lemon type, can go into more adult - themed areas. In the original, Hermione and Ron's relationship is more about friendship evolving into love in a very PG way. In fanfiction, it can explore their physical attraction and the more passionate aspects of their relationship much more deeply. It might also add new scenarios or character traits that are not in the original, just to fit the more romantic and sometimes racy nature of the lemon fanfiction.
Fanfiction often explores different scenarios for their admission. In the books, it's within the context of the overall plot against Voldemort. However, fanfiction can place them in modern - day settings, like they're at a Muggle university. This completely different setting changes how they admit their feelings, perhaps with less magic and more about getting to know each other in a new way.
In canon, trolls are mainly depicted as simple, brutish creatures. In Hermione and Troll lemon fanfiction, they can be given more complex personalities and motives. For example, a fanfic might make the troll intelligent in a different way than wizards, which is a big departure from the simple-minded trolls in the original books.
In the fanfiction, there's often more focus on their romantic relationship. The original story might not have explored it as deeply. Also, the fanfiction can take liberties with the plot, for example, changing the way they interact with other characters to suit the needs of the Zero - Kaname relationship.
In the original story, Hermione and Ron have a complex relationship that is full of love, albeit with some bickering. Fanfiction that has Hermione hating Ron completely goes against this fundamental aspect. Their friendship and later romantic relationship in the original are based on mutual understanding and shared experiences. So this kind of fanfiction takes a very different turn.
It differs mainly in that it's likely to have more unorthodox or unexpected elements. In the original, their relationship is more of a traditional father - daughter one. But in the lemon fanfiction, there could be situations where they team up in ways that are completely new, like solving a mystery together that was not part of the original plot.
In the original Naruto, there are very few romantic elements compared to the 'naruto lemon harem fanfiction'. In the fanfiction, there is a harem which means multiple characters are romantically interested in Naruto. This creates a whole new set of storylines that are not present in the original. Also, the 'lemon' aspect, if not overly sexualized, might add some emotional depth to the relationships that we don't see in the original Naruto. For example, more intimate moments of understanding between Naruto and the characters in the harem.
In the original story, the relationship between Jacob and Bella is more complex and restrained. But in lemon fanfiction, when Jacob imprints on Bella, it often becomes more about their immediate physical and emotional connection. The lemon parts usually mean there's a focus on their sexual relationship, which is not present in the same way in the original. In the original, there are more barriers and moral dilemmas, while the fanfiction might break some of those down to explore a more direct relationship between them.
The main difference is the addition of the lemon element. The original Naruto story focuses more on ninja battles, friendship, and the overall plot of saving the ninja world. But in the fanfiction, the lemon aspect might bring in romantic or more adult - themed relationships. Also, the Tsukuyomi in the fanfiction could be used in ways that the original story didn't explore, like creating more complex illusions for different purposes.
In the original Harry Potter story, Draco and Hermione are more like rivals. But in this fanfiction, they are in love. This is a huge difference. The fanfiction focuses on their relationship, while the original story has a broader scope about the fight against Voldemort and the wizarding world as a whole.
The original series is mainly focused on the wild adventures and scientific concepts. But in Rick and Morty lemon fanfiction, there's more emphasis on the emotional and relationship aspects, especially those related to the 'lemon' idea. The original has a broader scope of storytelling, while the fanfiction hones in on specific character interactions and feelings.
