He doesn't have to be a good person, that's fair. I just found myself not giving a shit. He lives in a dystopian authoritarian truthless hellscape, and all he cares about is the thrill of getting his dick wet under the Party's nose. His concerns are so small and hedonistic, I just couldn't care less. The backdrop of the world was far more interesting, but the book goes out of its was to not actually dig into all of that too much once the scene is set early on.
I've come to understand that, had I carried on reading, there is some payoff where the nympho turns out to be a honeypot or something? Or both of them are being monitored and get arrested by the regime? Or whatever? That would have made it like 10 percent more interesting I guess, but it just dragged on in his misplaced priorities for far too long to keep me going. A book should not be an exercise in endurance, in my opinion.
