The fanfic could be about Adrien being thrust into Marinette's life during a time of crisis. For example, if Marinette gets into some trouble with a supervillain while being Ladybug and Adrien, as Chat Noir, has to step in and take on her civilian life to keep her identity safe. He'd have to pretend to be her, interact with her friends and family, and learn a lot more about the girl behind the mask.
One possible plot could be a story where Adrien is suddenly thrust into Marinette's world in an unexpected way. Maybe a magical mishap causes him to swap lives with her for a day. He'd then have to deal with her daily routines, like her family's bakery, her school projects, and her friendships. This would give him a whole new perspective on Marinette and might even lead to some self - discovery for him.
Their relationship could develop in a very interesting way. At first, Adrien might be completely lost in Marinette's world. But as he spends more time there, he starts to understand her better. He realizes how hard she works, how kind she is to her friends, and this new - found understanding could lead to him developing deeper feelings for her. It could start as a simple friendship based on this new - found respect, and then gradually turn into something more romantic.
It could also be about the challenges they face during the pregnancy. Marinette might have health issues, and Adrien has to be extra careful and supportive. There could be a lot of emotional turmoil as they both grow up faster than they expected. They might also face some judgment from society, but they stand strong together to face it all.
One possible plot could be Marinette struggling to raise the baby on her own while dealing with the heartbreak of Adrien leaving. She might find support from her friends like Alya, who helps her through the tough times. Meanwhile, Adrien could be off on some self - discovery journey and later realizes his mistake.
One plot idea could be that they discover they're pregnant unexpectedly. Maybe they're still in high school and have to deal with the reactions of their friends and family. Their friends could be initially shocked but then become very supportive. Another idea is that an akuma attack somehow affects the pregnancy, adding a layer of danger and drama.
Another plot could be about starting a family. They both love children and start to think about having their own. But they also have concerns. Marinette worries about how she will balance her career and motherhood, and Adrien is a bit nervous about being a father. They talk to their friends and family, who give them different advice. In the end, they decide to take it one step at a time and are excited about the future together.
Well, a great plot twist could be that Marinette has a secret identity as Ladybug, and she's worried that the arranged marriage will interfere with her superhero duties. So she tries to keep it a secret from Adrien, which leads to all sorts of misunderstandings. Adrien, on the other hand, might have his own secrets related to his father's business or his own hidden talents that come to light during the arranged marriage situation. And perhaps, there's a prophecy or an old family curse that is related to their arranged marriage. It could be that if they don't fall in love and stay together, something bad will happen to the city. This would add an extra layer of drama and urgency to their relationship.
Well, they might start by simply petting the kittens. Maybe the kittens' soft fur and cute meows would make them forget about all their daily troubles. Adrien could be sharing some of his modeling experiences while Marinette shyly listens and giggles. They could also play with the kittens using little toys, like a ball of yarn, and have a really good laugh as the kittens chase after it.
One possible plot could be that Marinette and Adrien, after getting married, discover they are expecting a baby. They could face challenges like how to balance their superhero lives with impending parenthood. Maybe Hawk Moth resurfaces during Marinette's pregnancy, and they have to find a way to protect Paris and their unborn child at the same time.
The main appeal is the relationship between Adrien and Marinette. Their dynamic is both cute and complex. Marinette has a huge crush on Adrien but is often too shy to act on it, while Adrien is somewhat oblivious yet has a special connection with Marinette. This creates a lot of tension and anticipation in the fanfic.
One possible motive could be that in the fanfiction, Adrien is being controlled by some dark magic or an evil force. This external influence makes him act against his true nature and kidnap Marinette. For example, perhaps a villain has cast a spell on him to use him as a tool to get to Marinette, who might have some special power or knowledge that the villain desires.
