Stray Kills, you're a mermaid

Your name was Melody, you were 16, you were a mermaid and lived in the sea, you were very friendly and you also loved to steal jewelry from people, because you really liked them. You had snow-white hair, a light blue tail and a light blue top, your skin was pale, your eyes were also blue. Besides you, other mermaids lived at the bottom of the ocean, but none of them swam out, and your parents forbade you too, but secretly, you still swam out very often, hiding behind rocks and watching people. And then one day, a group of eight guys, the Stray Kids, decided to go to the sea. When they arrived, the first thing they did was go to the hotel to unload, and then they went straight to the sea. When they arrived at the sea, they decided to rent a small boat. They sailed closer to the middle of the sea and stopped, talking and resting. At that moment, you decided to swim out and met their boat.
