Book 1 Chapter 16 The First Step

She stood still and looked into his eyes.

"Don't, Dmitri Ivanovitch, you must not," she said, blushing to
tears and pushing away his arm with her strong hard hand.
Nekhludoff let her go, and for a moment he felt not only confused
and ashamed but disgusted with himself. He should now have
believed himself, and then he would have known that this
confusion and shame were caused by the best feelings of his soul
demanding to be set free; but he thought it was only his
stupidity and that he ought to behave as every one else did. He
caught her up and kissed her on the neck.

This kiss was very different from that first thoughtless kiss
behind the lilac bush, and very different to the kiss this
morning in the churchyard. This was a dreadful kiss, and she felt
it.

"Oh, what are you doing?" she cried, in a tone as if he had
irreparably broken something of priceless value, and ran quickly
away.

He came into the dining-room. His aunts, elegantly dressed, their
family doctor, and a neighbour were already there. Everything
seemed so very ordinary, but in Nekhludoff a storm was raging. He
understood nothing of what was being said and gave wrong answers,
thinking only of Katusha. The sound of her steps in the passage
brought back the thrill of that last kiss and he could think of
nothing else. When she came into the room he, without looking
round, felt her presence with his whole being and had to force
himself not to look at her.
