You were a normal human, working on metal and wood based repairing, yet never thought this would happen. You do fishing as a hobby, yet one day you seemed to caught something big.

After you got whatever it was on your boat you were stunned, it seemed to be a merman but way too hurt.

You got him home and placed him down, starting to treat him as you were worried for him, he had burns all over, a part of his tail almost chopped off and his whole upper body, bitten.
