Well, it's just a vanilla hentai with loving couples and maybe a little bit of romance. But the main aspect that is simple and focuses on the intimacy of these couples.Each couple has a chapter focused on their first time and their love experimentation.
The animation is acceptable and the design of characters despite being boring, can be entertaining or erotic. Being an anime vanilla does not have great scenes but it's still fun to watch.
My recommendation is that you should see it because as a vanilla hentai it can be entertaining, but if you have another anime with better production values then see it before.
