what does kafka reveal about the main character in the first paragraph ? what expectations does this set for readers'?

With one obvious exception-the protagonist's metamorphosis into a giant insect and his strangely calm reaction to this change-the story is so intricately described that we can almost imagine it happening in real life. Thus, almost nothing takes on any symbolic or metaphorical quality, since every object, action, and word can be seen as contributing to the realistic quality of the style. This attention to detail serves to focus the reader's attention on the one abnormal character-Gregor Samsa-for an understanding of the story's meaning.
