A unique way to develop their relationship could be through a shared secret. For example, they both discover something about a teacher or another student that they have to keep quiet about. This shared secret forces them to trust each other and communicate, which gradually changes their relationship from one of dislike to something more complex.
Perhaps there's a magical or supernatural element introduced. Maybe Lila gets cursed, and Adrien is the only one who can help her break the curse. In the process of trying to break the curse, they have to rely on each other, and this experience completely transforms their relationship. Lila might see Adrien in a new light, and Adrien might see a more vulnerable side of Lila.
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.
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 develop uniquely if Charlie starts teaching Renesmee about human history and culture. Since she has a vampire side, she might view things from a different perspective, and this exchange of ideas could deepen their bond.
One way is to put them in a situation where they have to rely on non - verbal communication. Maybe they are in a place where sound is not possible. They would have to learn to read each other's expressions and body language more deeply. This would force them to understand each other on a different level and strengthen their relationship. Also, they could be given a shared power that they can only use when they are in complete harmony. This would require them to work on their relationship constantly to be able to access this power.
Their relationship could be developed in a unique way if Joker starts to see Poison Ivy as more than just an ally in crime. For example, he could start to be genuinely interested in her plants and how they work. This newfound interest could make Poison Ivy see him in a different light, and they could start to bond over creating new plant - based weapons together.
Well, a unique way to develop their relationship could be by having them go on a road trip together. During the trip, they face various challenges like getting lost, running out of gas, etc. These shared experiences would bring them closer. Another idea is to have them volunteer at an animal shelter. Working with animals could show a different side of each other. They could bond over taking care of the cute little creatures. Additionally, if they were to get paired up in a dance competition, the physical closeness and the need to work in harmony would enhance their relationship in a new way.
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.
Their relationship could develop uniquely if Rachel takes on a teaching role for the younger glee club members under Will's guidance. This role reversal would force them to see each other in new lights and create a deeper bond.
A unique way to develop their relationship could be through a series of challenges. For example, they are trapped in a mysterious dimension together and have to rely on each other to escape. In the process, they discover each other's strengths and weaknesses, and Kurama realizes that Kushina is not just Naruto's mother but a powerful ninja in her own right. This mutual respect and reliance would strengthen their relationship.
Their relationship could be developed uniquely by having them start as enemies in a sense. For example, Sephiroth could be on a mission that Aerith unknowingly gets in the way of. But instead of killing her immediately, he's intrigued by her. This initial encounter could spark a series of events where they keep crossing paths. Each time, they learn a bit more about each other. Maybe Aerith starts to see the pain behind Sephiroth's cold exterior, and Sephiroth begins to respect Aerith's strength and determination. Over time, this could lead to a complex relationship that is part friendship, part something more, as they both struggle with their own destinies and how the other fits into it.
Another way to develop their relationship uniquely is if Aipom gets a prophecy about a great danger that Ash will face in the future. Aipom decides to secretly train itself extra hard to be able to protect Ash. When Ash finally discovers what Aipom has been doing, he is touched and their relationship becomes even stronger. This would show a different side of their relationship, with Aipom being the protector instead of the one usually being protected by Ash.
