Чертов нахал

The witty exchanges kept me hooked, but I wonder if the humor was based on real conversations or pure imagination. How did the author craft such natural dialogue?

His arrogance made me question whether he was genuine or just pretending to be tough. Did the story make others warm up to him over time?

The humor kept things light, but there were moments that felt surprisingly tender. I wonder if this contrast was intentional from the start.
