The long story short is that this manga (so far) probably shouldn't be read for the plot.

The art is nice and eroge, the chapter per chapter story is usually pretty formulaic, a few side characters actually have some interesting development, but the main two are completely surface level stand in's for the reader which does not make for compelling story. Honestly, if they had at least one or two chapters that broke the main characters formula every now and then, this would be one of my favorite eroge manga, and there does seem to be small moments where it could use expectations to it's advantage, but 42 chapters in, and there's only been the most miniscule glimpse of that happening. There is a b storyline with side characters however that actually seems to have an idea it's exploring, and when put on the background of the main 2 sexually charged and repressed characters, it shines so brightly, and it's done in only a few chapters.

This formula is the same every time.
protag:"Hi obvious love interest, x, y, or z is happening" love interest:*does something vaguely or deliberately sexual or even just physical to protag* protag:"WOAAAaAAAaaAHHHH!!! LOVE INTEREST!? WHAT ARE YOU DOOOIIIIINNNG?!?" love interest:"we should be a couple.............. jk :P" protag:"gorsh, stop messing with me, I know I suck"

There's not even really any background or motivation for these two to act the way they do. I mean, sure, the art is cute, but the speech bubbles practically have no point. I could not read them, write what they're basically saying down, then read them and have at least 80% accuracy. But the author has shown that they can do a good character driven story in this very manga, so I'm holding out in case that this will play out with some kind, any kind, just a sign of character development, but I'm not so hopeful.

If that's what you're looking for too, go read or watch 3d girl, it's basically this premise, but characters have depth.
