i've played no sexual visual novels before, and yeah the story is the most important, but now i'm 30yrs old, so fairy tale romances are somentimes boring, but don't get me wrong, if the romances are well writed like in this case they're all good, this is apply to NSFW stories too, so yeah i would.
Some NSFW Stories are boring AF, just sex focused, i mean yeah everibody loves sex but, why?, how? What make the characters reach to that point? How they develop their feelings? Those are the questions that need to be properly answered to make a Good and Interesting romance. And in additon makes tha story better.
Bc lets face it, a Good story doesn't need a Good romance, but a Good romance can be a Good story.
Sorry for mistakes, i'm not a native speaker.
