In many fanfictions about Lila and Adrien, their relationship can be quite complex. Sometimes, Lila tries to manipulate Adrien to get closer to his famous family or for her own gain. But Adrien, being the kind-hearted person he is, might initially be deceived by her lies, only to gradually realize her true nature as the story progresses.
In some fanfictions, Lila's scheme against Adrien could be part of a larger plot. She could be working with an enemy of the Miraculous holders. Since Adrien is Chat Noir, she might try to expose his identity or put him in dangerous situations to further her own goals. For example, she could pretend to be in trouble to lure Chat Noir into a trap set by the villains she's allied with.
One plot idea could be that Lila tries to frame Adrien for something he didn't do, but Adrien manages to prove his innocence with the help of his friends. This would create a lot of drama and tension in the story.
Their relationship could be developed uniquely by having Lila actually start to feel guilty about her lies when she sees how kind Adrien is. She might slowly try to change her ways, and Adrien, being the good - hearted person he is, could help her become a better person. This would be a very different take on their relationship compared to the usual animosity.
He could also be a bit worried. Adrien might think about the responsibilities that come with having a child. He might wonder if they are ready for this big step, considering their own lives and any potential challenges. He would then sit down with Marinette and have a serious conversation about how they are going to handle everything.
Alya would probably be super excited and start planning everything from baby showers to future playdates. She'd be there for Marinette every step of the way, giving advice and support. Nino might be a bit more reserved at first but would soon warm up to the idea and be a great source of comfort for Adrien, like helping him pick out baby clothes or build nursery furniture.
Another reaction could be that Marinette pretends to cooperate with Adrien at first. By doing this, she can buy time and look for an opportunity to escape or get help. She might act as if she is okay with what is happening while secretly planning her next move, like leaving a clue for someone to find her or finding a way to disable Adrien temporarily.
One possible scenario in a fanfiction where Lila is exposed could be that Marinette finally gathers enough evidence of all of Lila's lies. Maybe she records Lila admitting to her lies when she thinks no one is listening. Then Marinette presents this evidence to Adrien and their friends. They are initially shocked but then realize how they've been manipulated by Lila all this time.
One possible reason for Adrien to quit being a hero in fanfiction could be the toll it takes on his personal life. Constantly having to balance his superhero duties with his normal life, like school and relationships, might become overwhelming. For example, he might miss out on important events with his friends or family due to his hero responsibilities. Another reason could be a moral conflict. Maybe he discovers some dark secrets within the hero community that make him question whether he wants to be part of it anymore. Also, he could be forced to quit if his identity is exposed and it puts his loved ones in danger, so he decides to step away to protect them.
His friends might be really surprised at first. Marinette, for example, would probably be a bit flustered seeing Adrien with a cat tail. But then they would get used to it and might even find it cute. Some friends like Nino could make jokes about it in a friendly way.
