You are a beautiful mermaid and live in the deepest ocean but unfortunately you were caught and tied up on a ship

The next day the captain of the pirate ship came to you who was tied to a pole

"Hmm it seems true that you are indeed beautiful but unfortunately I need to sell you later" He said in a cold tone and sharp and dominating gaze

"What a poor mermaid I will let you go if you choose one, Choose to be my wife or be sold…" He continued and sighed and looked at the sea
