In some fanfictions, Adrian's reaction could be really complex. He might be overjoyed that the two people he cares about - Marinette and Ladybug - are actually one. But at the same time, he could be worried about how this revelation will change their relationship. He might be concerned about whether Marinette will still trust him with her secret identity and how it will affect their interactions as friends and potential more - than - friends in the future.
He could be shocked at first. I mean, he has been so close to Marinette all this time without realizing she was Ladybug. His reaction might include disbelief and then a quick acceptance as he starts to piece things together in his mind.
One interesting plot could be Adrian's initial shock and then his realization of all the times Marinette's behavior as Ladybug made sense in her civilian form. For example, her courage as Ladybug might be seen as her standing up to Chloe in her Marinette guise.
One idea could be that Adrien initially feels shocked but also a sense of relief. He might have always had a feeling that Marinette was special, and now it all makes sense. So he starts to view her in a whole new light, with more respect and admiration for her dual identity.
Perhaps Adrian overhears a conversation or stumbles upon a secret document that uncovers the truth about Ladybug. Another possibility is that a villain forces the reveal in a dramatic turn of events.
The relationship between Adrian and Marinette is full of ups and downs in the original story. So, seeing Adrian finally take the step to propose adds a new and exciting dimension. It's interesting to see how their dynamic changes from being friends or just having a crush on each other to something more serious. Also, the way Adrian plans the proposal, whether it's a grand gesture or a simple but heartfelt one, can be really engaging.
One great Marinette x Adrian fanfiction is 'A New Day'. It shows their relationship developing in a really sweet way. Another is 'Love in Paris' which has some interesting plot twists. 'Hidden Feelings' is also good as it delves deep into their unspoken emotions. 'Under the Stars' is a beautiful story that focuses on their moments together. And 'The Dance' is a fun read with a lot of cute interactions between them.
There is this fanfic named 'Discovery of a Lifetime'. Marinette discovers that there is a parallel Miraculous world that is linked to her own. This discovery leads her on a journey to explore this new world and find out how it relates to her role as Ladybug. The story has a lot of world - building and Marinette's character development is really interesting throughout the story.
I really like 'Felix's Redemption'. In this fanfic, Felix starts off as a rather antagonistic character, but as the story progresses, his relationship with Adrian evolves. It's interesting to see how they come to understand each other better, especially in the context of the Miraculous Ladybug universe with all its magic and mystery.
Their relationship would probably become more complex. Adrien might feel a new sense of closeness to Marinette.
Well, it could be a bit rocky at first. Adrien might be in disbelief and not know how to act around Marinette. But as time goes on, he could start to see all the times Marinette has shown the same qualities as Ladybug, like her courage and kindness. This realization would slowly bring them closer. For example, he might remember all the times Marinette has stood up to bullies at school, just like Ladybug does against villains. Eventually, they would have a deeper, more meaningful relationship.
In this breakdance fanfic, Adrian's character might develop a deeper sense of connection with Marinette. As they share this new passion for breakdancing, he might start to rely on her more and value her opinions. Marinette would likely develop a stronger sense of self - esteem. The physicality of breakdancing would force her to be more in tune with her body and her abilities, which would translate into her being more confident in other aspects of her life as well. Also, they both might learn about teamwork and cooperation as they create breakdance routines together.
