At the end of Volume IV, Part One, Chapter V, Nikolai is at a party and talking with the governor's wife who is encouraging him to marry Princess Marya. At the bottom of this collage I used the phrase "Il y Maniere et maniere" which means "there are ways and ways". She is playing matchmaker.
A few paragraphs in Chapter VI:
"But in the depths of her soul there was a harmony with herself, coming from the consciousness that she had suppressed in herself the personal dreams and hopes that had begun to arise in her with the appearance of Rostov."
Princess Marya is in love! -- Lola
