Who is Guy Montag and what he doing in the first paragraph of novel?

Guy Montag is the protagonist of Ray Bradbury's novel "Fahrenheit 451." In the first paragraph of the novel, we are introduced to him as a fireman, but not the kind who puts out fires. He works for a society where books are banned and his job is to burn them, along with the houses that contain them.

The opening paragraph describes him returning home from a day of burning books, feeling a sense of emptiness and a flicker of unease as he reflects on his job. He's described as a "mechanical" and "dull" man, yet there's a hint of something more within him.

The first paragraph lays the groundwork for Montag's journey of self-discovery and rebellion against the oppressive society he lives in.
