Help

I started reading a manga the other day but forgot to put it on my reading list, no I cannot remember the title.

Plot:
About an author who lives in a small town, and is well respected as his book is based on this town, so it brings a lot a tourists to the town, and earns lots of income for the local businesses.

The authors grandmother had recently passed away, and had made a promise to a mythical dragon to give her grandsons hand in marriage to the dragon, in exchange for her wish to be granted.

This dragon shows up at the town in human form to find his 'wife'.

Does anyone have a link for this manga?
