Chrysanthemums

How and why does the man use Elisa’s vulnerability to his advantage?

Every time the man asks for some type of work that he could be paid for Elisa gets annoyed and tries to send him away. However, once he finds her weakness, her Chrysanthemums, and begins to express his interest in them she doesn't a have problem with giving the man some pots to repair. Not only does she give him the pots to fix, she also is actually really attracted to him and has to hold her self back from reaching out for him. Later on in the story she becomes upset when she finds the flowers on the side of the road and realizes he was lying the whole time about him needing the seeds for another one of his customers.
