This is your heroine. She’s dancing for her life.
There are so many different ways to take this simple idea.
Maybe she’s distracting someone so her partner can attack and they can escape. Maybe she’s captive. Maybe she’s under cover and she knows her identity has been discovered so she’s buying time. Or maybe she’s traveled back in time and has found herself in the midst of a harem.
You decide what direction to take this story and how your heroine gets out of this dicey situation.
