Marinette is the main female protagonist in Miraculous Ladybug. She's a young girl with a kind heart and a secret identity as a superhero. As for Camemburt, it's likely a character made up for this particular fanfic idea. Maybe the author wanted to create a new love interest for Marinette, so they came up with Camemburt. But again, this is just speculation without actually reading the story.
Marinette could use her wits. If she's tied up, she might be able to find a sharp object nearby to cut the ropes. For example, if she's in a room with some old furniture, there could be a nail or a broken piece of wood that she can use.
Another reaction could be that Marinette pretends to cooperate with Adrien at first. By doing this, she can buy time and look for an opportunity to escape or get help. She might act as if she is okay with what is happening while secretly planning her next move, like leaving a clue for someone to find her or finding a way to disable Adrien temporarily.
A common theme is the development of their relationship. Since they have a unique dynamic in the original story, fanfiction often explores how that relationship grows and changes.
Well, one interesting aspect could be the unique character interpretations. In fanfics, authors often explore different sides of Lisa Lisa that might not be fully shown in the original work. It could also be interesting to see how the lemon aspect, which might imply some sort of romantic or spicy elements, is incorporated into the story in a creative way.
It's also possible that Lisa Davies is a transfer student from a different wizarding school. Her arrival at Hogwarts could stir up things as she brings with her different magical traditions and knowledge, which then affects the way the Hogwarts students view magic.
Since we don't have a clear understanding of what exactly these 'lisa lisa celebrity ghost stories' are, it could potentially be a new or emerging trend in the world of celebrity gossip or horror - themed entertainment. It might be a story that started on social media, where someone claimed to have a connection to Lisa Lisa and told a ghost - related story about her. Or perhaps it's a part of a local or niche sub - culture's lore that is slowly starting to gain more attention.
