My understanding is that the premise revolves around a harem centerpiece who *finally* doesn't act like a beta bitch and instead chads up to make his goals come true. I even read several reviews to that effect, and for a bit that fantasy seemed accurate. But then I realized that Joro always loses. He's always outwitted by the women (and men!), and all his fourth-wall-breaking diatribes and quips do is smokescreen the fact that he's the same old "heart of gold" harem MC like always.
I'm a seasoned purveyor and oftentimes shill of the harem genre, so I can at least give credit to Oresuki for being creative; the pseudo twists and turns make each episode seem a bit like detective mysteries and psychological thrillers. Unfortunately the seeds-and-nuggets approach that works for the detective genre fails completely here because the hooks/bait are pretty much always exclusive to flashbacks. You know, the flashbacks that usually reward keen viewers with an "a ha!" moment...except Oresuki halfasses it consistently. It doesn't matter if you noticed the bait or not, because there's always another aspect that wasn't there for you to pick up on.
As for the actual harem, it sucks. Through all twelve episodes Joro does nothing but act selflessly, thereby forcing all the women to fall completely in love with him. And that goes totally counter to the whole selling point in the first place. Yeah, every so often the "le evil genius" part of him is shown, but it truly feels more like the episode directors forgot until two hours before airing time and just had to throw something in so the TV stations wouldn't have to rewrite the series' blurb.
