We make a critical conceptual and documentary biographical analysis of the novel El dia que me quieras (by Osvaldo Rodriguez), in the context of both political and class tensions in Valparaiso during the 1960s. First, there will be a delimitation of conflicts from the concept of "transclass", to highlight the immanent tension to the constitution of the political subjects during the time. On the other hand, we will study the involvement of the author within the political project of Unidad Popular (UP), making an analysis of the relation of the biographical text with the literary discourse from the category of "transindividual". Finally, we will propose that historical and conceptual substratum of this novel can reflect the pressures on the conformation of the political and cultural models of the UP, from the immanent referents to the literary field, those who announce the political catastrophe that will happen with the coup d'etat of 1973.
