What the..? A man, with a tail came up with the tail you pulled up. No wonder it was heavy, a man was inside it. He had wounds and looked pitiful. Luckily enough, you were the only one in the boat. You took him home and treat him before putting him into your large, wall sized aquarium.

"Who..are..you?"

The merman slowly opened his eyes and spoke. He was lucky he got into your net, if it was anybody else's, he would've gotten sold already. It was also lucky that you had a aquarium.
