The storyline could develop with Annabeth first reflecting on what went wrong in their relationship. She might write in a journal all the things she misses about Percy. Then she could take the bold step of showing up at Percy's new place unannounced. This would shock Percy but also open the door for communication.
In this fanfic, the development might be centered around Annabeth's growth. She could start to change for the better, becoming more understanding and patient. As she changes, Percy starts to hear rumors about her new self. Curiosity gets the best of him, and he decides to see for himself. This leads to them meeting again, and Annabeth has to convince Percy that she's a different person now and worthy of a second chance.
Annabeth could try to be more understanding of Percy's needs. In the fanfiction, she might give him space at first, but then slowly show up in his life in small, positive ways. Like bringing him his favorite food or helping him with a difficult task without being pushy.
One possibility is that Annabeth has to face some challenges to prove to Percy that she truly wants him back. She could be on a quest to find something important to Percy, like a lost item from his past. This would show her dedication. Also, there might be some new characters in the fanfic who try to stop her from getting back with Percy, adding more drama to the story.
There could also be external factors. For example, there might be a prophecy or some sort of danger that keeps Percy away from Annabeth. He might be so focused on dealing with this external threat that he doesn't have time or energy to think about getting back together with her.
In this type of fanfic, the relationship might develop when Percy is put in a situation where he has to pretend to be Annabeth's boyfriend for some reason. As they play the part, Percy starts to notice little things about Annabeth, like the way she smiles when she's truly happy or how she gets excited about architecture. These small observations could start to chip away at his obliviousness and make him question his own feelings. Meanwhile, Annabeth hopes that this pretend relationship might turn into a real one, and as they go through different scenarios together, their relationship could grow from a one - sided love with Percy being oblivious to a mutual, deep - rooted love.
Percy's reaction could be complex. Initially, he'd be hurt and angry. But as time passes, if Annabeth is sincere in her attempts to get him back, he might start to question his own feelings. He could be torn between his love for her and the pain of the betrayal.
Percy might develop more of a steely determination. In Tartarus, he has to face extreme danger, which could make him even more resolute in protecting Annabeth and getting out. Annabeth, on the other hand, could become more resourceful. She'd have to use her wits in this strange and deadly place.
Often, it starts with some build - up of tension between them. Maybe there are some misunderstandings or moments of jealousy that heighten the emotions. Then, as the story progresses, there are small, intimate moments that lead up to Annabeth's growing desire to kiss Percy.
In such a fanfic, the plot could be very complex. Maybe Annabeth realizes she made a huge mistake. She might start by trying to approach Percy subtly, like showing up at his favorite places. But Percy would be hurt and angry. He might initially reject her attempts. However, as she keeps trying, she could start to show real remorse and explain the reasons for her cheating, which could be due to some external influence or her own insecurities. And Percy might gradually start to question his own feelings towards her again.
In this fanfic, Percy could develop a darker side. The horrors of Tartarus might make him more ruthless when it comes to protecting himself and Annabeth. Annabeth, on the other hand, may become more empathetic. She could see the pain and suffering of the other beings trapped in Tartarus and try to help them, which would shape her character in a new way. Also, their relationship would develop further. They would have to trust each other completely, and this could lead to a more mature and deep connection between them.
The story could start with Naruto slowly distancing himself from Konoha. He might start by not taking on any more missions for the village and instead focus on building his own power. For example, he could seek out new jutsu training from other places or with rogue ninjas who oppose Konoha.
