I'm liking that the woman is non-white.

If you are going to do a prequel, can you make her the same ethnicity as a man? I see this a lot with TG stories. You rarely if ever see an Asian or black man transform and if there's an Asian or black woman, she was previously a white man.

If you have already made the story and the character was previously white... fine. But I'm just saying this as food for thought for next time.
