Love, etc... [Russian]

A triangle: love, obsession, and choice. Pierre, a ladies' man who has little cash and no fixed residence, describes his best friend Benoît as the world's oldest 32-year-old. The shy, well-employed Benoît's life changes when he answers the personal ad of Marie, a 25-year-old who restores paintings. He's attracted to her and she likes his steady calm and his honest attention. They're soon a couple, and they include Pierre in their dinners, outings, and trips. What will happen when Pierre realizes that he too is in love with Marie?
