I don't understand your question. Have you read Faulkner's "A Rose for Emily" and you don't understand it? Or have you not read it and you want someone to tell you what happens so you don't have to read it?
I'll tell you what's at the center of the story in case you don't understand it, but I won't give you plot details so you don't have to read it.
Faulkner often writes about the South in the period following the Civil War. The South was devastated by the war: its economy was destroyed, and most of the battles and raids and destruction took place in the South. This story is about the recovery, or lack of it. It is a bit of an allegory about refusing to let go of a glorious past.
Emily, once a member of the aristocracy, has been "reduced" to a "commoner," so to speak. And she refuses to accept the reduced status.
The story is allegorically about the lengths a person will go to in order to hold on to a glorious past.
