Since it's about an alpha's hidden obsession, the alpha themselves is probably a central character. There could be a love interest, perhaps someone who gradually uncovers the alpha's hidden side. And also, there may be antagonists who either oppose the alpha because of this obsession or are in some way related to what the alpha is obsessed with.
The main theme might revolve around the discovery and exploration of this hidden obsession. Since it's an alpha, they are likely to be in a position of some sort of leadership or dominance. Their hidden obsession could be a factor that both empowers and challenges them. It could be something that sets them apart from others in their world, and as the story unfolds, we may see how this obsession shapes their decisions, relationships, and ultimately their fate.
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.
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.
It could be an intense and all-consuming interest in a particular novel or type of novels. Maybe you can't stop thinking about the story or characters.
