The story develops at a well enough pace. I don't like arranged marriages so I'm a bit biased against the story, but overall the manga did well in making me like the characters and their relationship.
The art is great. The setting is interesting and well-built.
Quite a sweet manga with a reasonable, to-the-point climax. Give it a go, especially for the art!
The art is fantastic, and the storyline and characters are both excellent too! Absolutely worth the read. I can't wait to see what this mangaka comes out with next!
