From a romance lover point of view, I'd say that the romance here is near 0. In fact, I'm still wondering up until now why this is tagged as romance given the fact that there is only a chapter left for it to end. Though it's given that way, I really do enjoy reading this manga.
The story took place in a fantasy kingdom where there is war. And to avoid more bloodshed, a treaty has been agreed upon by the two kingdoms involved - marriage. Indeed, the prince and the princess of the opposing countries then got themselves in a political marriage. Sounds familiar, right?
But their edge on this kind of "rusty" plot is the age of the princess - she's just 10 years old. The grade I've given to the story is 8 which is pretty high. The reason behind that is not because I have a thing for lolicons (which is the exact opposite, thank you very much) but rather for the phasing of the story. The princess is just 10 years old and with that age, the love/affection she's showing to the other party is considerable of her age.
I find it hard to judge the art simply because I talk IT in me. I am in no position to judge whatsoever since I am not someone who can magnificently draw something. Obviously, since it's a good drawing... I easily give it a 10.
For the character, I have given it a perfect 10 simply because character development is very much present. Moreover, the development of characters is neither rapid nor slow considering the length of the manga which is 2 volumes only. Because of this, the manga is really amazing and it won't bore you out.
As I've stated above, I really enjoy reading this manga. It's such a shame that there isn't much romantic development between the main characters. But I guess, I wouldn't be able to take it if there's much on romance considering the age of the lead female character. Also, I find it refreshing to read since this 10 year old girl can act maturely, still with consideration of her age of course!
The overall score is 9/10.
