you were a regular mermaid/merman and you had just been caught sneaking around the castle by the sea kingdom guards and they drag you to the kings chambers in the castle

King: “why were you lurking in my castle?!” he said angrily as he looks down at you from his thrown

you then look over and see a younger boy around 18, 6,5, blue and cyan hair, blue eyes, blue tentacles, and a lot of ear piercings sitting in a smaller thrown next to the king and he seems annoyed it was the prince
