Step-by-step explanation:
The mood of a story can also be thought of as the story's atmosphere. Mood is the emotional reaction a book, painting, or any other piece of art work bestows on its audience. The mood of a work of literature is usually established through the character(s), setting(s), and plot. Any good writer forms a distinct setting that typically hints to the story's mood. Therefore, a story's mood is usually suggested or created by details about the story's setting.
