Is this novella is about hidden motives?

When a person needs something he or she is looking for ways to achieve it, and, as it often happens, we don’t waste an opportunity to use other people to satisfy our desires. Miss Bordereau is poor and she gives in rent her house to a strange man and wants him to marry her niece not because he is a man of honor, but because she thinks that he has a lot of money. The narrator is looking for the ways to make friends with two ladies in order to get the Aspern papers and Miss Tita proposes the narrator because she feels miserable and doesn’t want to stay lonely after her aunt dies. Self-interest is the great power that makes people lie, blackmail, mask their real individuality. But one should remember that sometimes the game is not worse the candle and the thing you longed to achieve is useless and meaningless. The most important thing here is to remain a person who cares about other people’s feelings because as you sow you may bow – the great truth of life.
