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.
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.
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.
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.
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 the fanfiction world, their personalities might be very complementary. Annabeth is intelligent and strategic, while Percy is brave and impulsive. This yin - yang dynamic could lead to a strong attraction, and the want to kiss could be a natural outgrowth of that attraction.
Well, it completely shatters their trust. Percy would be devastated and feel extremely betrayed. He would question all their past interactions and wonder if Annabeth ever really cared about him.
One possible reason could be a misunderstanding. Maybe she saw Percy doing something that she misinterpreted as a betrayal of their friendship or their cause. For example, if Percy was seen talking secretly with an enemy, Annabeth might jump to conclusions without knowing the full story.
Annabeth could show her determination by going out of her way to be in the same places as Percy. She'll be wherever he is, whether it's at his favorite spots or events he attends. And she'll always be there with a kind word or a helpful gesture, constantly reminding him of their connection. Also, she might face any danger or difficulty that comes her way while trying to get close to him again, showing that she's willing to do whatever it takes.
There's 'A Future Together'. It focuses on Annabeth planning a surprise wedding for her and Percy. The story details her thoughts and feelings, like her excitement and nervousness, which makes it a great read for fans of the concept.
