I just looked up the culture of Bacha Posh and I think this story would work better as an "eloping" story i.e. running away from family to be with your loved one. Consider this passage from an article on euronews:
'For some, reverting back to their biological gender can be a traumatic experience.
"When I put on girls' clothes, I thought I was in prison," explains Najieh, who grew up as a 'bacha posh', although she would attend school as a girl.
Now 34-years-old, married and with four children of her own, she weeps for the freedom of the male world she has lost.
"I wish I could be a man, not a woman. To stop this suffering."'
So here's my question regarding Kinaaz's situation: was she also forced back to covering herself? Or was she instantly sent to London right after turning 18? Because that can influence the way she views and presents her identity.
Regarding earning that wrath: it's written in a way that's more realistic, however, that would not translate well into a story. The audience will feel off with such pacing.
Fighting for girls rights needs to be scrapped off because like the comments said, the story would venture off nowhere. The parents accepting Kizaani doesn't happen magically either. That's not how things works. Their whole lives they've been educated to think this way, and any other way is incomprehensible to them. That's why they need something harsh to change their mind.
Interesting story btw. Would love to work with it.
