A heartwarming moment could be when Annabeth surprises Percy with a scrapbook she made. It has pictures (drawn or magically captured) of all their memories together, from their first meeting at Camp Half - Blood to their latest adventure. Percy would be really touched by this as it shows how much she values their relationship.
One great example could be a fanfic where Annabeth arranges a secret date for Percy at their favorite spot in Camp Half - Blood. She decorates it with sea - themed items for Percy, like shells and a small pool filled with glowing fish. Another example might be a story where Annabeth surprises Percy with a quest she's planned all by herself, just for the two of them to go on and have an adventure.
Percy, the son of Poseidon, and Annabeth, the daughter of Athena. Percy is brave and impulsive at times, while Annabeth is more level - headed. Their different personalities add to the charm of the story where Percy surprises Annabeth at school. It's their relationship that drives the plot forward in this fanfiction.
Well, perhaps Percy shows up at Annabeth's school with a bouquet of her favorite flowers. He could have skipped his own classes to come see her. He might wait outside her classroom and when she comes out, she's completely shocked and overjoyed.
Percy could show up at Annabeth's high school during a big event like a pep rally. He sneaks in, disguised as a delivery person. When he finally reveals himself to Annabeth in the middle of the crowd, she's shocked but overjoyed. They hug and Percy tells her he couldn't stay away any longer.
Well, perhaps Annabeth decides to surprise Percy at his high school by disguising herself as a new student. She enrolls in the school for a day and joins Percy's class. When Percy sees her sitting there, he can't believe his eyes. She then reveals her true identity during lunch break and they have a sweet reunion, sharing stories about their latest demigod adventures.
One day, Percy was having a normal day at Goode High School. He was sitting in class, half - listening to the teacher, when suddenly Annabeth walked into the classroom. Everyone stared as she made her way straight to Percy. She had a big smile on her face. 'Surprise!' she said. Percy's face lit up immediately. He had no idea she was coming. They hugged right there in the middle of the classroom, much to the amusement of their classmates.
Maybe Percy brings her a special gift from his adventures, like a unique seashell. Annabeth would be really happy and they might share a sweet moment in the schoolyard.
One possibility is that Percy is in the middle of a boring class at Goode High when Annabeth shows up. He might be so shocked and happy that he forgets all about the lesson. They could then sneak out to a quiet place in the schoolyard and catch up on all their adventures and how much they've missed each other.
