Lonely Lullaby

She's a runaway and he's her bully. She left for good, never to be heard of again. He's the reason she left and it's his main regret. They both loved each other but neither of them knew it. What happens when Percy calls her up one day? He needs to set things straight and this is the only way to do it. Things will turn upside down for these 19 year olds soon. Perceabeth! Rated T.
