An 'obsession novel' is likely a type of novel where the plot or a character is centered around an obsession. For example, it could be a character's obsession with a person, an idea, or a goal. This obsession then drives the story forward, creating various conflicts and plot developments.
First, you need to know the original Harry Potter world really well. Read all the books, watch all the movies. Then, think of an interesting concept. It could be a new adventure for Harry and his friends, or a different take on an existing event. For example, what if Hermione had been sorted into Slytherin? Next, create your characters. They can be new ones or expanded versions of existing characters. And don't forget to give your fanfic a good plot structure with a beginning, middle and end.
Begin by choosing a theme. It could be love, power, or friendship within the Twilight context. Next, create your own unique characters or expand on existing ones. For example, you could give a side character a more prominent role. As for the writing process, start with an engaging opening that grabs the reader's attention. Maybe start with a dramatic scene like a vampire attack in a new location in Forks.
First, think about your own experiences as a fan or what you imagine an extreme fan might feel. Then, create a relatable main character. For example, you could start with a simple idea like a girl who has posters of Harry Styles all over her room and can't stop thinking about him. Build a plot around how this obsession affects her daily life, like missing school or work because of a concert.
Next, plan out your plot. You could start with a simple premise like Danny noticing the Demigheist for the first time and then becoming fixated. Build on that by adding in conflicts. Maybe Danny's friends don't understand his newfound obsession and try to pull him away from it. Also, make sure to give your story an arc, like Danny learning something important about himself through this obsession.
A secret obsession story could be about someone's hidden passion or fixation. For example, a person might have a secret obsession with collecting old stamps. They keep it a secret perhaps because they're afraid of being judged or they just like having something that's entirely their own private interest.
Not necessarily. 'Obsession' could be a completely made-up tale or have elements borrowed from various sources rather than being directly based on one true incident. It depends on the specific context and the author's imagination.
