Zvi Litvinoff's wife, Rosa is much younger than Zvi. She rescues him from his lonely life in Chile, befriending him outside a café. Zvi ends up claiming The History of Love as his own work, at least partly because he wants to woo Rosa. Rosa eventually discovers the truth about the book, but keeps it a secret from Zvi and the world (she's good at keeping secrets). As further evidence of her devotion to Zvi, she writes the introduction to the published version of The History of Love.
