Sanine by Mikhail Artsybashev

When Lida Sanine received Lialia's invitation, she showed it to her brother. She thought that he would refuse; in fact, she hoped as much. She felt that on the moonlit river she would again be drawn to Sarudine, and would again experience that sensation at once delicious and disquieting. At the same time she was ashamed that her brother should know that it was Sarudine, of all people, whom he cordially despised.

But Sanine at once accepted with pleasure.
