Why do you want an overly deep and complex narrative to what is effectively a fetish game? I don't want the author to focus on a grander narrative, I want them to focus on what drives me to read and engage with it, IE, the very thing it WANTS you to engage with. I don't need the author to create some huge, omega class world building and deep intricate lore for their clearly fetish based visual novel. And isn't that the point of Eugene's character? At least from what I have gathered, he's a slippery conniving self-serving man who is really only doing this because he likes doing it, not because he's genuinely invested in people's lives and improving them, which is perfectly fine with me. I don't need a protagonist to be relatable all of the time, sometimes I just want to read a story where what I see is more or less exactly what I get. The characters, the plot, the stakes. All of it.
Of course this could all be subject to change, but I don't know, it kind of feels like you expected this to be something it just won't be and should not be.
