Good premise, I must say. I liked the attention to detail in the backgrounds, they’re very well done, and I like that they use different colors for the night sky, which keeps it from being monotonous to see the same starry sky all the time. I find it funny how Nazuna blushes when talking about her feelings or cute things, but when it comes to sex (literally), she doesn’t. As for the protagonist, I’m not quite convinced yet.
