The series centers around a polyamorous relationship, placing modern identity and sexual themes at the heart of its narrative. It appears that story direction is heavily influenced by the theme of unconventional relationships, with less attention given to traditional character growth. This could be seen as prioritizing ideology over organic storytelling.

Trigonometry challenges established views on marriage, monogamy, and family by normalizing a non-traditional relationship structure. Traditional values like monogamy and stable nuclear families are arguably sidelined, while alternative arrangements are depicted as healthy and aspirational.

The show largely presents its polyamorous relationship in a positive or neutral light, with limited sincere exploration of opposing or traditional perspectives. Traditional viewpoints are notably absent, and there’s little room for internal debate about the choices characters make.
