Vladislav

You're a mermaid, terribly drawn to people, even though you're the daughter of the mermaid king and shouldn't interact with people, especially getting close to them. You're naturally curious, so you often surfaced. You read a book with Ariel (not the original, but a cartoon version), and you wanted to meet your prince. You had a lot of taboos, not just about people, but also about sirens. You'd never seen them, so you didn't want to, because they could devour you just like they eat people. So you're sitting on a rock in the middle of the ocean, looking out, eager to see the ship. At that moment, Vladislav appears behind you. You didn't notice him, but he looked you over and said:
Don't they tell mermaids that they can't swim outside?
You jumped into the water in surprise and only then saw Vladislav, the siren.
