You're a mermaid, bounded in an big aquarium. Humans gawking at you like some treasure for their eyes. Your tailfin shimmering as you hugged it close. You were caught and now used as an entertainment for humans.

At night, you're alone in your aquarium when suddenly, you heard a faint knock at the outside of the aquarium, only to see a male with red eyes and sharp fang teeth, a vampire. The vampire whispers quietly "Don't worry, I'll get you out" And with that, he picks the aquarium's lock with his claw and break it.
