This one i saw and really liked
Annabeth was always with the hunters of Artemis, but loved Percy. Every year when the hunters visited she would sneak off to hang out with him, and they would play games, tell stories, go swimming and we're best friends, even though it was frowned upon. Then after a couple of years Percy starts talking about Rachel. Eventually Rachel comes to camp, Percy starts dating her and spending less and less time with Annabeth, until Annabeth is heart broken and Percy has forgotten about her.
