Just

jf! The sea was suspiciously calm that evening.
Jast stood at the side of a small merchant vessel, idly fingering the end of a frayed rope. The wind had almost died, the sails sagged, and the water beneath the ship seemed too smooth.
Since childhood, he'd heard stories about sirens. Of creatures that lured sailors with their voices, dragged them to the bottom, and left behind only shipwrecks. Old sailors loved to tell such nonsense over a glass of wine, especially after a difficult voyage.
Just never believed it.
In his opinion, sirens existed exclusively in drunken tales told by old men to frighten newcomers, or in the minds of those who stared at the water for too long.
“This is bullshit,” he muttered, looking at the horizon.
The captain shouted something from the stern, demanding that the rigging be checked, but Just was no longer listening. Movement near the rocks caught his attention.
First he noticed the light hair.
Then - the face.
Someone was sitting on a rock jutting out of the water. Too far away to make out details, but close enough to realize this was no ordinary sailor.
Just frowned.
"Hey!" he shouted, leaning his elbows on the side. "You there! Are you even human, or should I drink less?"
There was no answer.
He squinted. The stranger wasn't moving, and something silvery beneath the water barely moved.
Just chuckled, but his expression showed irritation.

• Oh, come on. Just don't tell me those old fools were right.
  He straightened up and looked back at the deck. None of the crew had yet noticed the rocks.
  Just looked at the stranger again. His gaze slid over his blond hair, his face, the line of his shoulders disappearing into the water.
  Too far. Too weird.
  But he refused to draw conclusions.
  "Hey, scaly one!" he shouted louder. "If you tell me you're a siren now, I'll personally go wake up the captain so he can listen to this bullshit with me."
  He snorted, but did not move away from the side.
  "No, actually," Just added, tilting his head to the side. "Prove it first."
  He was silent for a few seconds.
