Who might deface a dark romance novel?

In a 'his gift a dark billionaire romance novel', the main characters are probably a wealthy, powerful billionaire male. He might be a bit of an enigma, with a dark side to his personality. The other main character could be a female lead. She could be an independent woman who catches the billionaire's eye. His gift to her of the novel could be a way to initiate their connection, and as they interact more, they start to uncover each other's secrets and fall in love.

Perhaps it's a young girl. In Salem, many young girls were involved in the accusations. The main character could be a girl who has a different view, a voice that goes against the hysteria, and she's in the dark because her ideas are not popular or accepted at that time.

Dumbledore could be seen as the main antagonist from Harry's new perspective on the dark side. Dumbledore represents all that is good in the wizarding world, and if Harry has turned to the dark, Dumbledore would be the one trying to stop him, to bring him back to the light. So in this context, Dumbledore becomes the opposition that Harry has to face.

It might be a story about two chefs. One works in a high - end restaurant and the other in a small family - owned diner. They meet in a cooking competition and start to fall in love while competing and also learning from each other's cooking styles.

Voldemort would likely be the main antagonist still. He might see Harry's potential as an animagus as a way to strengthen his own forces. His Death Eaters would also play a role in trying to convince Harry to join the dark side.

Maybe an amnesiac character. They've lost their memories and don't remember anything about the vampires and other supernatural beings. They are the perfect candidate to be kept in the dark as they have no prior knowledge to start with. Their journey to regain their memories and discover the truth about the Vampire Diaries world could be the main plot.

Kagome could encounter other skilled fighters from different realms. They might be human - like her - but with extraordinary abilities. Or she could run into some strange and magical creatures that are only found in the area where the Dark Tournament is held. There could also be some characters who are there for their own secret reasons and Kagome gets caught up in their plots.

It could be Naruto. Since it's a Naruto - related fanfiction, Naruto is a likely candidate to be the main character. He might be the one who discovers the dark dragon sword and has to deal with the consequences of having such a powerful weapon.

I think it could be a horror genre. The 'dark' often gives a sense of horror, and if there is something above that is dark, it could be a source of fear, like a dark spirit or an unknown and terrifying entity.

The main theme could be mystery. Because a dark room often hides things that are not immediately visible, and this creates an air of mystery.
