The setting of "the chrysanthemums" contributes to the solitary character of Elisa.
Explanation:
The setting of this story is a secluded place away from society, because of the winter mist. The place looks more like an isolated prison of everything and everyone, it is a true "closed pot". The description of the setting during the narrative gives to the reader a sense of claustrophobia and highlights the unique character of Elisa.
As this scene is the home of Elisa, she lives isolated from everyone, has no one to keep her company or to establish a friendship, so she feels lonely.
