TL;DR: Light-hearted, sweet, low on drama, hilarious, and nice character development sounds for you? Then go ahead.

This manga was just pure awesomeness for me. At first I thought I'd give it a 9, but after thinking about it I couldn't think of anything I would change, so I went with a 10 after all.

This manga is in its fundamentals a typical shoujo/josei light-hearted romance story. Woman has a difficult life, gets helped by a man, and so they get to know each other. However, what this manga does incredibly well is the entire execution of it.
Their dialogues are often incredibly funny (and that goes for both sides, they are often quite witty) to the point of even having me laugh out a few times, there is no unrealistic love octagon going on to entail drama, and most importantly: Character development! Throughout the entire manga, all the important characters develop steadily and visibly (and in a realistic pace and manner), none of them feel stagnant. On top of that, the ending was very well put together, all the pieces falling into place, and compared to other manga, it already started leading up to it throughout the entire manga, which made the ending feel very fitting, not rushed or out of place whatsoever.
