One interesting Marinette and Cat Noir fanfiction could be where they have to face a new villain that has powers they've never encountered before. In this story, Marinette might struggle with her identity as Ladybug while also dealing with her feelings for Cat Noir. Another could be a time - travel fanfic, where they go back in time and meet their predecessors as superheroes.
There are fanfictions where Marinette and Cat Noir get trapped in an alternate dimension. They have to rely on each other more than ever to find a way back home. It shows their growth as characters and how their relationship deepens in the face of such a difficult situation. Also, some fanfics explore what would happen if their identities were revealed accidentally to their friends or family, which leads to a whole new set of challenges and plot twists.
One common theme is the discovery of their true identities. Since they don't know each other's secret identities in the show, a lot of fanfiction focuses on how they find out about each other. Another theme is their relationship development, from friends to something more romantic.
There's also 'A Kiss in the Rain' which is quite well - loved. In this story, the setting of the rain adds a lot of romantic tension. It shows how their relationship develops to the point of that kiss in a very natural way. It also has some really sweet dialogue between Cat Noir and Marinette that makes the kiss even more meaningful. The story goes into their insecurities and how they overcome them to reach that moment of closeness.
One popular scenario could be during a battle where they are about to be defeated and in a moment of desperation and realization of their true feelings, they share a kiss. This kiss might give them a sudden burst of power to defeat the villain. Another could be at a school dance. Marinette is hesitant at first but Cat Noir sweeps her off her feet and they kiss under the twinkling lights. And there's also the scenario where they are alone on a rooftop, looking at the city, and the atmosphere just leads to a tender kiss.
Another storyline could involve a situation where they are forced to hide their feelings in public but when they are alone, like in an abandoned building that they've made their secret hideout, they engage in making - out. It adds an element of secrecy and excitement to the story.
No, it is not appropriate. 'Miraculous Ladybug' is a popular animated series aimed at a wide audience including children. Writing sexual fanfic about the characters goes against the family - friendly nature of the show and can be considered inappropriate and disrespectful to the original work and its fans.

Write about their friendship development. Maybe explore how they gradually become better friends outside of their superhero duties, like having normal conversations or sharing hobbies. It can add depth to their relationship in a positive and appropriate way.
Marinette and Cat Noir have a complex and endearing love story. Marinette is in love with Adrien, not realizing that Adrien is Cat Noir. Meanwhile, Cat Noir is drawn to Ladybug, who is actually Marinette in disguise. They fight side by side against villains in Paris. Their relationship is filled with misunderstandings, yet there are also tender moments when they see the good in each other. It's a love story that is slowly evolving as they get to know each other better in their superhero and civilian identities.
One key moment is when they first fight together as Ladybug and Cat Noir. It's the start of their relationship as superhero partners. Another is when Cat Noir saves Marinette in her civilian form, which shows his care for her without knowing she's Ladybug. Also, the times when Marinette as Ladybug has to rely on Cat Noir during tough battles are important. These moments build the foundation of their love story.
