Gurov is less concerned with personal shame than Anna, but he still feels the need to keep the affair secret. Before and after kissing her in public, for example, he looks around furtively to see if anyone is watching.
Anna no longer cries at the thought of her sins; instead, her tears now revolve around the hardship of keeping their love secret from the world. At the end of the text, the narrator even observes that Anna and Gurov forgive "everything in the present." To them, their love is no longer a source of shame, but rather something beautiful and tender.
Thus, Chekhov's characters start out believing their affair is immoral and sinful, yet the story concludes with them believing that it is the most beautiful part of their lives. In this way, he demonstrates how the passage of time and the evolution of relationships can impact people's perspectives on the moral universe.
