Just some vague ideas.
One- I play a young elven girl, tired of the busy elven city life. Decides that the quiet forests were much more to her liking. Little does she know she is in the middle of dragon territory.
Two- A female centaur finds her self being tracked. female centaurs are rare to come by. And she had spent most of her time, hiding from those her mother had warned her about. Until one unfortunate day, as she was gathering or fishing, whatever, she is spotted, and the chase is on.
Three: I play a new student. Quiet, and shy, yet hot, and quite the eye catcher. Has most men at the school wanting her. But she has no interest in men. Least right now. your guy tries to win her over
Four: Evicted yet again she turns to her uncle for shelter. Her uncle owns a large safe haven for creatures of sorts, both wild, and domestic, exotic. (even fantasy.) He hasnt seen her since she was a girl but now she is grown, and he is having thoughts that an uncle shouldn't have about his niece.
