Obviously, Ladybug and Chat Noir are likely to be involved. Their relationship is a central part of the Miraculous Ladybug story. If it's about 'back to us', it could be about them getting back to their strong partnership after a fight or misunderstanding. They are the ones who protect Paris together, so any change in their relationship affects the whole 'us' in the city.
Another interpretation could be related to the overall theme of the Miraculous Ladybug world going 'back to us'. This could involve the restoration of Paris to its normal state after a series of akuma attacks. The fanfiction could explore how the city and its people, including our beloved heroes, are trying to get back to their daily lives, with Ladybug and Chat Noir leading the way. It could show how they are dealing with the aftermath of the chaos, both physically and emotionally.
The main characters are usually Ladybug and Chat Noir. Since they are the central heroes in the Miraculous Ladybug universe, it makes sense that fanfictions about handcuffs would involve them. They are the ones who are most likely to get into such a situation, whether it's due to an akuma's power or some other plot device.
Well, of course, Ladybug and Chat Noir are the main characters in most of these fanfictions. They are the ones who usually have to deal with any situation involving the masks. Marinette, who is Ladybug in her civilian form, might be involved in trying to figure out the mystery behind a strange mask she finds. And Adrien, as Chat Noir, will be by her side, using his charm and skills. Sometimes other characters like Alya or Nino might also get involved, for example, if they accidentally come across a mask with some sort of power and end up in the middle of the action.
Obviously, Ladybug and Chat Noir are the main characters. Their relationship is at the center of most of these fanfictions, especially when it comes to a pregnancy plot. They are the ones who would be directly affected by the situation.
It could be Alya. She's very curious and adventurous. Maybe she gets too close to some sort of werewolf lore or a werewolf in disguise while investigating for the Ladyblog. And then she gets bitten and turns into a werewolf. This would add a whole new layer of drama to her relationship with Marinette and the other characters.
In this fanfiction wedding, not only their friends but also some of the heroes they've worked with in the past could be guests. Rena Rouge and Carapace would be there, having played important roles in many battles. Maybe even some of the one - time heroes like Pegasus or Viperion could show up. Ladybug's parents would be there with open arms, and Adrien's bodyguard could also be present, having seen Adrien grow up. And Paris itself could be considered a 'guest' in a way, as the city has been a big part of their lives and the reason for their superhero existence.
Another possibility could be a new character introduced specifically for the fanfiction. Maybe a powerful and charming hero from another city comes to Paris to help Ladybug and Chat Noir. He and Ladybug develop a connection, and he could end up being the father. This would create a lot of drama and new storylines, especially when it comes to how Chat Noir reacts to the situation.
Simon is, of course, a central character. His character is often explored more deeply in fanfiction. Writers might give him a backstory, motives, and emotions that aren't fully explored in the original show. His power to make people follow his commands in the 'Simon Says' game makes him a formidable adversary.
The two main characters, Ladybug and Chat Noir, are the most common in Miraculous Ladybug tickle fanfiction. Their dynamic as superhero partners and the underlying romantic tension between them is often explored through tickle scenarios. But other characters can also be involved. Marinette, who is Ladybug in her civilian form, might be part of a story where her friends find out she's ticklish and playfully tickle her. Similarly, Adrien, who is Chat Noir, could be in a situation where his family or friends engage in some tickling fun with him. But overall, Ladybug and Chat Noir are the stars in most of these fanfictions.
Ladybug and Chat Noir are often the main characters in such fanfiction. Their complex relationship and unspoken feelings for each other make them perfect candidates for love spell - related stories. Writers might explore how a love spell could either strengthen or complicate their relationship.
