One is the profound, frenzied, and unpredictable love between Lev Nikolayevich and his wife of almost fifty years; the other is the fictional love affair of Tolstoy's earnest young secretary Bulgakov and a pretty, progressive young acolyte Masha.
On the other hand, there was a very amusing, though highly improbable scene of Sofya Andreyevna's playful "seduction" of her beloved Lev Nikolayevich; furthermore there is no doubt that the one scene of passionate lovemaking between Bulgakov and Masha resulted in the movie's R-rating (Restricted), "For a scene of sexuality/nudity."
From the late 1880s, she felt that Lev Nikolayevich, who had retained copyright to his books, had foisted onto her the responsibility for dealing with publishers, something she felt he should have handled.
Both she and Lev Nikolayevich were interested in photography, an art she actively promoted and that she herself practiced.
On the evidence of My Life (and of other sources known to me), Sofia Andreyevna and Lev Nikolayevich did not practice contraception, nor is there clear evidence that they deliberately spaced out their children; indeed, My Life suggests that Sofia Andreyevna resented the impossibility of planning her family and felt herself the victim of her husband's impulsive advances.
