It seems you are referring to the — likely the Dutch final secondary school exam ( eindexamen ) for the subject Hemel (astronomy/space science) at the Oostelijke Kantonale en Regionale Universiteit ? That doesn’t quite fit.
On the surface, Hemel is fiercely independent, highly provocative, and driven by an insatiable appetite for fleeting sexual encounters. She drifts through casual hookups, sometimes asserting dominance and other times placing herself in emotionally or physically degrading positions to feel something .
The tension in the film escalates when Gijs falls for Sophie, a stable and domestic woman. For the first time, Hemel's "rock-solid" bond with her father is threatened by a more mature form of love that she does not know how to emulate. This shift forces Hemel to confront the reality that her lifestyle is not sustainable and that she may eventually be forced to "grow up" and find a connection that exists outside the shadow of her father.

Hemel uses sex as a proxy for intimacy, showing that physical closeness does not always equal emotional connection.
: Hemel's physical explorations serve as a metaphor for her internal struggle to find herself outside of her relationship with her father. Paternal Bond
