Dude, they don't get animated just to satisfy you (or minority). There's a reason for only certain mangas get to be animated. They won't be animated unless they think it'll sell. This manga isn't that amazing (was just decent for me), but if you have read all chapters, it still does have the story (it's not only about hc sex, or rape) and the characters. Its sale ranking in Japan is pretty high. The characters seem to be pretty popular. I guess Japanese girls are more attracted to these kind of characters.
Shhiitttt junjou And sekaii are huge hit animes and there is sex on like every page of those damn things lol in sekaii I noticed where there was sex in the manga it was tweeked a little to either not have the sex scene at all or just show making out. In junjou it just shows a couple of the sex scenes and you don’t see like dicks or anything lol

I'm reading this because I heard there is going to be an anime of it so I thought I'd read the manga. This has too much sex to be turned into a shounen ai to be honest so I wonder how they're going to pull it off. But if they end up doing it, then maybe there is a chance for one of my favorite yaois "totally captivated" to be animated as well. Aside from being Korean (most animes are based on japanese manga and not korean manhwa), I didn't think it stood a chance because it has too much hardcre sex but if this can make it then why the hell can't "totally captivated"
