As an inveterate dragon lover this has all my stamps of approval.
Especially the bit where the girl is, by all appearances, much more obviously interested in the dragons than the boy, much as she may like him. I mean, the romance can come too, but this girl, she has her priorities straight! >:'D Dragons are way cooler than boys. (Actually the boy seems to perhaps care more about dragons than the girl, too, though that's less clear. If so, a perfect couple!)
Basically this manga was made for me and I love it.
