The film focuses entirely on a heterosexual relationship. There is no visible presence of non-cisnormative identities or critiques of heteronormativity within the character arcs.

Catherine is not a submissive domestic anchor; instead, power dynamics are fluid and abrasive. The film avoids the 'competent husband' trope, presenting a man whose instability contributes to domestic decay.

The film adheres to a homogeneous European casting profile. It does not engage with racial or ethnic diversity, focusing instead on specific socio-economic class dynamics.

The narrative rejects prescriptive morality and the sanctity of the home. It portrays the domestic partnership as a site of exhaustion and cyclical dysfunction rather than a stable pillar.

There are no prominent depictions of physical or neurodivergent disabilities within the narrative.
