In this fanfic, Percy and Annabeth could face some challenges. For example, the babysitting job might be a part of a quest. The kids could be in danger from some mythical creatures. Percy and Annabeth would then have to protect them while also taking care of their basic needs. They might also teach the kids about Greek mythology and their own powers, which could be really interesting.
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.

But then a rival school turns out to have some sort of demigod - related threat, and they have to work together to overcome it while still trying to win the sports event or the club competition.
Well, they might have a really emotional moment. Percy could run to Annabeth and just hug her tightly. They would probably share all the things that happened to them while they were apart. Maybe Percy would tell her about some new adventures and the challenges he faced, and Annabeth would listen intently.
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.
Well, one possibility is that Percy finds out and is heartbroken. He might distance himself from Annabeth completely. In the fanfic world, this could lead to Percy going on a self - discovery journey, finding new friends or allies. Maybe he even meets someone new who helps him heal from the betrayal.
