One common theme is the exploration of their relationship. It shows how they support each other during this new phase of life. For example, Adrien might be extra protective of Marinette.
Family reactions are also a big part of it. How their friends and family, like Alya and Nino, react to the news. Maybe their parents are excited about becoming grandparents. It often delves into the family dynamics.
One common theme is the 'will - they - won't - they' situation. Since Marinette is so shy and Adrien is a bit clueless about her feelings, a lot of fanfics play around with this dynamic.
One common theme is the 'slow burn'. It shows Adrien gradually realizing his feelings for Marinette over time, through shared experiences like working on a school project together. Another theme could be the 'jealousy' aspect, where Adrien gets jealous of other guys who are around Marinette. This can add an interesting dynamic to the story as he starts to figure out why he feels that way. Also, the 'secret identity' theme often plays a part. Since Marinette is Ladybug and Adrien is Chat Noir in the original show, sometimes in the fanfic, Adrien's realization of his feelings for Marinette is intertwined with his relationship with Ladybug, which creates a complex and exciting plot.
One common theme is Adrien's internal struggle. He's often conflicted about his growing obsession with Marinette while also trying to maintain his normal life and friendships. For example, he might feel guilty for spending so much time thinking about her instead of focusing on his studies or superhero duties.
Some fanfics might also focus on Marinette's own growth during the pregnancy. She might learn to be more responsible and strong, facing challenges that come with the physical and emotional changes of pregnancy. There could also be elements of how she manages her daily life, such as school or her design work, while being pregnant.
'The Kiss in the Rain' is another great one. The setting of a rain - soaked Paris adds a lot of romantic charm to their kiss. The story leading up to the kiss is filled with tension and longing, making the actual kiss all the more satisfying for the readers.
A common theme is the 'will - they - won't - they' situation. The story keeps the readers on edge, wondering if they'll finally get together. It's like a dance between the two characters, with Adrien being shy about his feelings and Marinette being both excited and scared about the possibility of Adrien liking her.
Protection is another theme. His possessiveness is sometimes rooted in his desire to protect Marinette from harm, whether it's physical harm or emotional harm from people who might not have her best interests at heart.
One common theme is the role - reversal. Usually, in the original show, Marinette and Adrien are around the same age, but in these fanfictions, with Marinette being older, she might take on a more protective or guiding role towards Adrien. Another theme could be the exploration of a different kind of romance. The age difference adds a new dynamic, and it can lead to stories where Marinette is more mature in her approach to love compared to the usual portrayal. For example, she might be more hesitant because of the age gap.
Another theme is self - discovery. As they figure out their own feelings, they also discover more about themselves. For example, Marinette might realize how her shy nature has both held her back and also made her more endearing to Adrien. And Adrien may discover that his public persona as a model is different from who he really is inside, and Marinette helps him with that self - discovery. This all ties into their earned desire as they become more confident in themselves and more desirous of each other.
One common theme is domestic bliss. They are often shown enjoying simple things like cooking together or having movie nights at home.
