Sora no Iro, Mizu no Iro is not bad, the art style is very good and the animation is nice too. The plot is pretty simple, a bit typical but still fun, one main male character two lead female characters one a transfer student who at first can not stand him but after wearing her down falls for him, then the other a girl who has known him longer who has had a crush for a while. Hajime is not bad for a hentai protagonist, he’s not a creep or a loser or anything like that. And seems he cares in his own way. Asais pretty hot and fun to watch how she slowly falls for Hajime.
Natsume I feel could have been developed a bit more tho her character is still interesting in a way.
