In the end she died and he was left alone, although in reality he had been left alone several years before her death, Emilia's death. Let's suppose that she is called, or was called, Emilia and he is called, was called, and is still called Julio. Julio and Emilia. In the end Emilia dies and Julio does not die. The rest is literature:

The first night that they slept together it was by accident. There was a exam in Spanish Syntax II, a subject that neither of the two had mastered but, as they were young and theoretically ready for anything, they were also ready to study Spanish Syntax II in the house of Vergara twins. The study group ended up being a bit larger than expected: someone put on music, then someone said they were used to studying with music, someone else brought vodka, arguing that it was difficult to concentrate without vodka, and a third went to buy oranges, because it seemed to him unbearable to drink vodka without orange juice. At three in the morning they were perfectly drunk, so they decided to go to bed. Although Julio would have preferred spending the night with one of the Vergara sisters, he quickly resigned himself to sharing the maid's room with Emilia.

Julio did not like that Emilia asked so many questions in class, and Emilia disliked that Julio passed courses even though he barely went to university, but that night both discovered a fondness that any couple is capable of discovering.  Moreover this is to say that they did horribly on the exam.  One week later, for the do-over exam, they again went to study with the Vergaras and slept together again, although this second time it was not necessary that they share a room, because the twins'parents had traveled to Buenos Aires.   

A little before getting involved with Julio, Emilia had decided that is the future she would fuck like the Spanish, that she would not make love to anyone, nor screw or hook up with someone, much less do it or get it on.  This is a Chilean problem, Emilia said at that moment to Julio, with a clarity that is born only in the darkness and in a low voice of course: This is a problem of young Chileans, we're too young to make love, and in Chile if you don't make love you can only do it or get it on, but I woudnt like to do it or get it on with you, I would prefer that we fuck, like in Spain.
