图书馆已经关闭了半个小时，图书管理员罗萨里奥(Rosario)正在书架上摆放最后几本书，抹去大学咖啡馆服务员阿曼多(Armando)在几本小说中潦草写下的下划线。也就是说，直到她发现它们不是简单的下划线，也不是阿曼多写的。

The library has been closed for half an hour already 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.
