A frisk novel could refer to a type of novel that has a lot of brisk or lively elements in it, perhaps in terms of the plot which moves quickly, the characters who are energetic, or the writing style that is dynamic and engaging.
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.
Their relationship can develop through shared responsibilities. As they prepare for the baby, they'll have to rely on each other more. Sans might take on more tasks to ease Frisk's burden, and this can strengthen their bond.
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.
Their relationship would become more mature. They would have to rely on each other more. Instead of just being friends or lovers, they are now co - parents. They would have to communicate better to take care of the baby's needs.
It often starts with curiosity. They meet in the Underground and are intrigued by each other. As they spend more time together, they start to trust one another. For example, Frisk might show Chara the power of kindness, and Chara might show Frisk some of the secrets of the Underground.
She might befriend Iron Man first. Since he's into technology and Marinette is quite creative when it comes to making things. They could bond over creating new gadgets or improving existing ones.
