A lot better than I first thought. The MC is a typical wishy-washy pushover sararyman stereotype, but he has skills and knowledge of his own which is a pleasant change. The queen is that rarest of characters: an actually feminine monarch and military commander who is competent at her job and knows her business. I was highly impressed that they managed this when so many others are bullshit Holly/Bollywood caricatures of that type. It's very simplistic, but they actually have a good, reasonably mature romantic relationship.
The politics are vaguely accurate to real world shenanigans, the antagonists of the story are intelligent characters in and of themselves, and the pacing is appropriate for a low-medium depth storyline.
8/10.
