They probably talk it out. Percy, being more impulsive, might initially be a bit stubborn. But Annabeth, with her logical mind, would lay out the facts. For example, if they disagree about where to go on vacation. Percy might want to go to a beach, but Annabeth wants to visit an ancient ruin. They would discuss and maybe end up going to a place near a beach that also has some ancient ruins to explore.
One cute moment could be when they go on a picnic by the beach. Percy tries to show off his fishing skills to Annabeth but ends up getting splashed by a big fish. Annabeth just laughs and they end up sharing the fish he finally catches for lunch. It shows their easy - going and loving relationship.

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.
It's appealing because it's a different take on the Percabeth relationship. It adds an element of 'what if' to their story. It's exciting to see how they would handle such a big step at a young age.
