The coming-of-age story was released just weeks after the Supreme Court ruled that the terms "woman" and "sex" in the 2010 Equality Act "refer to a biological woman and biological sex" in April this year.
The campaign group For Women Scotland had brought a case against the Scottish government arguing that sex-based protections should only apply to people who are born female. The Scottish government had argued in court that transgender people with a gender recognition certificate were entitled to the same sex-based protections as biological women - but it was defeated.
After the ruling, the judge stressed the law still gives protection against discrimination to trans people, but some campaign groups said it rolled back years of understanding.
There are concerns from some advocacy groups that there is a wider pushback against LGBTQ+ representation in entertainment.
A recent report by US-based organisation Glaad (Gay & Lesbian Alliance Against Defamation) found a "continual decline" in the number of LGBTQ+ characters on broadcast television, but an increase on streaming services.
Newsbeat has been told media watchdog Ofcom collects some diversity data on actors and presenters employed directly by broadcasters, but not on characters within shows.
