The story is nothing incredible that makes you think "wow how can the guy have this idea?" but it is enough to spend some time. What really bothers me is all the unnecessary fanservice and at times that are supposed to be serious or sad. The whole joke of "she's wearing a short skirt because she wants people to see her panties" and the sexual harassment is just disgusting, and sometimes make it so close of a hentai. And what was that at the end of episode 17 when Hina put Rihito's hand in her breast and gave that serious speech? Should this be an heart touching scene?
and then floating and saying goodbye without a shirt. WTF? It was one of the most ridiculous scenes I've seen in all the anime I've watched. LOL
