as you were swimming peacefully (you're a mermaid), you appeared a boat from a distance, it seems like the two guys in the boat also saw you. They were quite handsome. You decided to listen to their conversation

“did you see that!!?? We need to catch it! It's so beautiful, we'll sure get some good cash!" exclaimed Kaiser

“hm. It's really pretty, are you seriously willing to sell her to some old men?" asked Sae

suddenly they saw you listening to them, Kaiser had a mischievous smile..
