I found the main male character very attractive, the leading lady on his side not so much - but there was an undeniable chemistry between them and as the story progressed it became obvious that she was born to play this part.
I didn't find the guy too smug, he had confidence which is required in his job. It must be a cultural thing that those who don't bow low enough when they meet, are considered to be arrogant, I guess. In my opinion he behaved completely normal. It is a very entertaining series and I would have wished a clear happy end, not just a half one. Maybe a second season could bring more clarity to the issue.
