In a plotline, Adrien gets rejected by Ladybug when he confesses his deeper feelings for her. This rejection shatters his heart, and he becomes more reserved in his interactions with her. However, this also gives him time to focus on his other relationships, like his friendship with Nino. As he spends more time with Nino, he discovers new hobbies and interests that help him grow as a person, and he gradually realizes that his life doesn't solely revolve around Ladybug.
One possible plotline could be that Adrien gets rejected by Ladybug, and this makes him question his self - worth. He might start to withdraw from his superhero duties for a while, thinking that he's not good enough. His friends notice the change in him, but he doesn't want to talk about it at first. Eventually, he realizes that his identity as Chat Noir is more than just being Ladybug's partner and he starts to focus on protecting Paris in his own right.
He could become more self - reflective. After the rejection, Adrien would likely take time to think about what went wrong and what he could do differently. This might lead to him becoming more mature in his approach to relationships.
A great fanfiction idea could be that Adrien and Kagami are paired up for a school project. As they work on it, they start to realize that they have more in common than they thought. They could share their dreams and fears, and this new - found closeness might make Adrien question his feelings for Ladybug a bit more.
One possible story could be that Adrien gets akumatized because he feels constantly overshadowed by Ladybug. In this fanfiction, Hawkmoth might prey on his insecurities. As an akumatized form, Adrien could have enhanced physical abilities like super strength and speed. His akumatized look might be a dark version of his Chat Noir costume, with a more menacing appearance.
In such a fanfiction, one possible reason could be the intense pressure he faces as a model and son. Constantly having to meet high expectations and having little personal freedom might drive him to despair. For example, his father's strict control over his life and his public image could make him feel trapped.
I can't really recommend or go into detail about spanking - related plotlines as they may not be suitable or appropriate for all audiences. However, in general Miraculous Ladybug fanfiction might explore different relationships between the characters, like Ladybug and Cat Noir's partnership, or their individual struggles with their secret identities.
It could be related to his emotional state. Adrien has a lot of pressure on him, both as a model and as Chat Noir. The stress could have taken a toll on his health, causing him to collapse and be hospitalized. In the fanfiction, this could be the starting point for his friends, like Nino and Alya, to realize how much Adrien has been hiding and struggling, and they could come together to support him in a new way.
In a fanfiction, Ladybug could get hurt as a result of a trap set by Hawkmoth. He might have studied her fighting patterns and set up a situation where she is lured into a place full of obstacles that cause her physical harm. This would not only test her physical strength but also her mental resilience as she tries to figure out how to escape and continue her fight against evil.
There are many interesting fanfictions out there about Adrien's car in Miraculous Ladybug. Some might focus on Adrien using his car to go on secret adventures while being Chat Noir. For example, he could use the car to quickly reach a location where an akuma attack is about to happen. The car could also be a place where he has some private moments to think about his double life and his feelings for Ladybug.
Well, in this fanfiction about Adrien's confession, it could go in different directions. If it's set during a battle, he might blurt it out unexpectedly. For example, he thinks they're about to be defeated by an akumatized villain and he doesn't want to die without Marinette knowing how he feels. Or it could be a more planned confession, where he has prepared a whole speech and even gets her a special gift, like a handmade charm related to their Ladybug and Chat Noir adventures.
