However, the second ring was not for her, but for his boss's daughter. Irina was devastated. Unable to accept her beloved's betrayal, she decided to take her own life. At the entrance to the pharmacy, where the poor woman had gone to buy a lethal dose of sleeping pills, she encountered an abandoned dog. Upon learning that the poor animal was being taken to the slaughterhouse, Irina was overcome with compassion and decided to take it in.
