A really interesting plotline could be them facing some sort of external threat that tests their relationship. Like a new demigod arrives on campus who has a mysterious past and seems to be causing trouble. Percabeth has to work together as a married couple to figure out what's going on and protect their college and each other. It adds an element of adventure to their married college life.
Some fanfictions might focus on their cultural differences in college. Percy being more of a laid - back, beach - loving guy and Annabeth being a more studious, architecture - focused person. When they get married in college, they have to learn to blend their different lifestyles. For instance, Percy might introduce Annabeth to his surfing friends, and Annabeth might take Percy to some high - brow architecture lectures. This can lead to some really cute and funny moments in the fanfiction.
Another possible plotline is the seven and Percabeth getting transported to a completely different realm, like a parallel universe where things are both familiar and strangely different. They would have to figure out how to get back home while also dealing with the unique challenges of this new world. This could involve making new allies and enemies, and exploring different cultures within this parallel universe.

One possible plotline could be Percy and Annabeth facing challenges similar to Cinderella's. For example, Annabeth might be treated unfairly by some characters, like the step - sisters in Cinderella. Percy could then come to her rescue in a heroic way, perhaps saving her from a difficult situation at a ball or an event.
The relationship could also grow through their experiences living on campus. Maybe they end up in the same dorm building. They could run into each other in the common areas, like the laundry room or the cafeteria. These small, everyday encounters would gradually build a deeper connection. Percy could learn about Annabeth's coffee addiction as they often meet in the cafeteria in the morning, and Annabeth could discover Percy's habit of leaving his shoes outside his dorm room.
In Percabeth fanfiction, their meeting and marriage often involve a lot of adventures first. Percy and Annabeth have a strong bond from their quests in the original series. Writers might show them meeting again in a new situation, like in a modern city far from Camp Half - Blood. Their marriage could be a grand event with all their demigod friends in attendance, celebrating their love that has survived so many challenges.
One common theme is the growth of their relationship. In college, they face new challenges and experiences that either strengthen or test their bond.
Another plotline might involve Naruto being a bit of a slacker in college at first, while Hinata is a studious student. Hinata then tries to help Naruto improve his grades, and in the process, they start to fall for each other. It could include study sessions filled with some awkward but cute moments.
One interesting plotline could be Caroline and Klaus adjusting to living in a new supernatural - friendly community as a married couple. They might face challenges from old enemies who are not happy about their union.
In some fanfictions, mortals might meet Percabeth married while they are out on a normal day in the city. The mortals notice their wedding rings and start a conversation. Percy and Annabeth then share some of their adventures, like their time at Camp Half - Blood, but in a way that doesn't reveal too much of the demigod world to the mortals.
One great fanfiction is 'A New Meeting'. It shows how mortals interact with Percy and Annabeth in their married life in a really interesting way. The story has some really cute moments where the mortals are in awe of their relationship.
