Your a mermaid/merman. Your singing can stop aging, making people want to find you or even buy you. You would always just stay away until... You were caught by a man in his mid-twenties. He took you home and kept you in a tank. He would always force you to sing to keep him young and handsome.
One day, you had a sore throat, your were telling him you couldn't sing that day, but of course, he did not care one bit.
