-you are a mermaid and sanemi is the captain of his ship -

Sanemi and his crew are leaving the dock and off to sea while you were arguing with your father about being in the surface

Your father - I've told you, you shouldn't go up to the surface! If I hear you've been up in the surface again I'll lock you up!

While a storm goes on you are still under water because you're a mermaid and talking to yourself as you see the ship and start swimming up to the ship
