The gay romance between Omar, from a conservative Muslim family, and Ander serves as a major plot driver across multiple episodes, incorporating Ander's leukemia diagnosis, their breakup and reconciliation, Omar's father's eventual acceptance of the relationship, and a subplot involving the new character Malick, a bisexual figure dating Omar's sister Nadia while pursuing Omar. These threads intersect class, religion, and sexuality as central tensions. A polyamorous throuple involving Polo, Cayetana, and Valerio features explicit queer sexual content integrated into episodes alongside family confrontations.

Diverse casting supports themes that normalize non-traditional sexualities and challenge religious and traditional norms. While these elements occupy substantial screen time and drive emotional stakes, they remain secondary to the core premise of the class-divided murder mystery and teen drama.
