I don't own Percy Jackson and the Olympians. So uh enjoy!
Aquamarine
Nico hated swimming, or rather, he hated water, especially the ocean. But it wasn't his fault, not really. Children of the Big Three weren't exactly meant to cross into another of the domains. Much like Percy didn't like to fly or enter the Underworld, Nico didn't like the ocean. He knew that below its shimmery aquamarine surface lay treacherous waters. He was the Ghost King after all; he knew how many souls this deceitful element claimed every single year. And he didn't want his own to be one of those. And yet… he couldn't resist Percy's pleads to join him in the sea. How could he? Percy was worth the risk of going into the treacherous sea.
