This is just a small drabble that's actually a part of an old AU fic idea titled "The Siren, The Angel, And The Demon".
The story is about Percy, Jason, and Nico who are a siren, an angel, and a demon respectively, and they go on this quest to stop an evil force from destroying their world. It's mostly just a jercico bromance fic with some slow burn jercy.
It was an old idea, and somehow I completely forgot about it.
"You were really brave back there." Jason said trying to break the tension between them. "Luring all those pirates away with your voice."
Percy snorted. "Thanks. But my voice isn't that great."
"I like your voice."
"You do?" Percy turn to him like he can't believe what Jason just said.
"I do." Jason cupped Percy face in his hand, and look into his eyes. "It's sweet and alluring, just like you."
Percy couldn't help but blush a bit at the compliment. "You think i'm sweet and alluring?"
Jason though about kissing the siren in front of him right then. But then they heard Nico walking back from the forest and they instantly broke apart with matching blushes on their faces.
