Maybe in this high school fanfiction, Percy is on the swim team and Calypso is the manager. There's a big competition coming up and they have to work together to make sure the team is ready. Along the way, they develop feelings. Calypso helps Percy deal with his insecurities about the competition, and Percy shows Calypso that there's more to life than just being popular.
A possible plot could be that there's a mystery in the high school. Percy has a strange feeling about it and Calypso, being the curious one, joins him in the investigation. As they dig deeper, they face various challenges and also start to have a romantic connection. They might discover that an old curse from the school's past is starting to resurface and they are the key to stopping it.
One idea could be Percy and Calypso exploring a new magical island together. They encounter strange creatures and have to rely on each other's skills to survive. Another could be a scenario where they share a moment of self - discovery while making lemonade from magical lemons on Calypso's island. It could also involve them using their powers in a unique way to solve a mystery related to an ancient lemon tree on the island.
Maybe they start a family in a hidden part of the world. Percy could teach their children about his demigod skills and Calypso could pass on her knowledge of nature and magic. It would be a story full of family adventures and protecting their new life together.
One idea could be that Percy and Calypso find themselves in a strange new world within the chaos, where the rules of magic are all jumbled. They have to rely on each other's unique abilities to survive. For example, Percy's water - controlling skills and Calypso's nature - based magic might combine in unexpected ways to fend off the chaotic creatures they encounter.

Calypso shows Percy a new part of the island that she has created in her loneliness, and they share a tender moment there.
A really interesting plot would be if Percy's friends from Camp Half - Blood transfer to Goode High for some reason. They all have to adapt to the mortal school life while also dealing with the threats that follow Percy, like a vengeful demigod from an enemy camp who wants to expose Percy in the middle of his mortal school life.
One idea could be Percy trying to hide his demigod powers from his high school classmates while still using them to solve normal high school problems like bullying. Another could be Percy forming a secret club in school for other kids with special abilities. Or maybe Percy getting into a friendly rivalry with the school's star athlete in a non - combat - related sport like track and field.
