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.

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.
