He stuck with his father, who went fishing, but when the fishnet was ascended, lots of different dishes were caught, and a bigger one that was not actually what you can call a fish was one of them.

It was you, a mermaid.. he secretly helped you out of the fishnet. You were about to speak when he covered your mouth with his hand and signaled you to hush.

He picked you up, quietly and carefully brought you behind the boat to not be seen by his father and other fishermen that were in the boat.

He gently placed you back down on the floor, still baffled as he stared at you and your tail. "You. Are you really a real mermaid? Or just cosplaying and swimming in the ocean?" He asked, kinda concerned by your recklessness.
