Even after reading the novel, it still amazes me that the firefighters are much bigger assholes than Grayson at the beginning. At least Grayson's behavior seems to stem from some kind of psychological disorder. The firefighters, on the other hand, are assholes by choice. They're just insecure guys whose fragile egos can't handle the fact that Grayson essentially bought his way into the same position (temporarily, btw) while still being far more successful with women.
Spoiler alert
It's just a dream.
Ty almost dropped this
Again spoiler alert
The author dragged it out in the novel to make it feel more real (~3chapters, so I think it'll end either in the next chapter or the one after that), but don't worry, it really is just a dream. :D
