Anna Karenina Part 6, Chapters 1-7
The Levins take many summer guests into their home, including two characters named Koznyshev and Varenka. Koznyshev's fiancée died before the two could marry; he became lonely and now finds himself attracted to Varenka. About to propose, he backs down.
Stiva arrives later for a visit and brings a friend named Veslovsky. Levin gets jealous because Veslovsky flirts with Kitty. But Veslovsky is just a flirt. He goes to see Anna and flirts with her too. The two principal women react differently to this man, as do the two main male characters.
