The library has been closed for half an hour and Rosario, the librarian, is setting the last few books on the shelfs and erasing the underlining that Armando, a waiter at the university’s café, has scribbled in several novels. That is, until she discovers that they are not simple underlines and that they haven’t in fact been written by Armando. When she looks up, she finds Armando standing in front of her.

Hace ya media hora que la biblioteca echó el cierre. Rosario archiva los últimos préstamos y borra enfadada los subrayados que ha dejado en varias novelas Armando, el camarero de la cafetería de la universidad. Hasta que descubre que no son simples subrayados. Ni los ha hecho él. Cuando alza la mirada, encuentra a Armando de nuevo en la puerta.
