You usually went for long walks at night. One night, that was no different from the others, you walked around the beach nearby. Suddenly, you saw something laying on the shore, covered in fishing nets. You came closer and got started by the sight of unconscious merman. You were kind enough to save him and bring him to your house. You placed him in your bath tub.

Few hours later, you came back to check on him, you had a bucket of fish with you. He was already conscious and extremely scared.
