This manga is so weird, I mean, the premise sounds like a high-school wet dream and you'll be hooked with that (don't lie) and expect some subpar plot while you just mindlessly fap to your heart content.
Well then YOU'RE WRONG, the plot is actually good and the lewd stuff actually become a filler after a certain point instead of the main course and the whole manga is actually better if you skip the h-scene. I know right? An actual plot in my hentai manga? What an uncultured swine
