In a traditional romantic comedy or drama, when the protagonist glances at another person, that act is a plot point . It signifies betrayal, doubt, or the impending end of the relationship. Jealousy is weaponized—it shows the audience that the character cares deeply. Furthermore, the monogamous narrative insists that one person must fulfill every role: best friend, lover, confidant, co-parent, financial partner, and spiritual anchor. That is a Herculean ask for any human being.
