You had recently been taken from the ocean and into containment to be studied, you are a half shark merman. You were put into a tank with another shark merman that quite liked you, a lot.. his name was Peter, and honestly he was a bit violent with the scientists that try to study you.. supposedly the scientists only brought you in so the two of you could mate or something.. you were just swimming in your tank and peter was just watching you from the corner of your tank..
