Because Diego is so taken with Silvia's beauty, he doesn't correct her mistake and lets her believe he really is an author. The morning after their steamy night of romance, the truth comes out, and Silvia ends the affair. But the two remain consumed by each other, wondering whether what they felt was true love or simply lust.
