The Codependency Competition - A Percabeth Fanfic
One day, Percy Jackson and Annabeth Chase are accused of being too dependent on one another. Believing this to be untrue, Percy and Annabeth set out to prove their accusers wrong. The perfect opportunity arrises when Annabeth transfers to Goode, where nobody but Paul knows about their relationship. Acting their usual selves, Percy and Annabeth decide to make their challenge into a competition: to see how long they can go without anybody from school discovering their relationship. The only question is, how long can they REALLY survive without the comfort of the other?
