The book originally featured a cis female Camila, but the adaptation reimagines her as César (pre-transition) in 2006, played by non-binary actor Nila, with the adult version by trans actress Alice Marcone (who also wrote episodes). Episodes depict César using an emo persona to express femininity amid bullying and homophobia in a conservative town, with Anita actively intervening to support self-discovery and acceptance.

This setup explicitly addresses lack of LGBTQ+ representation hindering trans self-recognition, per writer statements. Creators including Gautier Lee (non-binary lesbian) and the diverse writers' room prioritized positive, drama-free coming-out narratives and contemporary identity themes over the source material's lighter teen drama.

The time-travel premise serves as vehicle for these subplots, including toxic masculinity critiques and gender/sexuality exploration, making ideology central rather than incidental. Reception includes praise for sensitive handling alongside backlash labeling it "lacração" for prioritizing message-driven representation.
