Okay but like

I think you just took this story to serious. Most yaois are like this so no use wasting brain power and wondering what's happening and why.

You say "most yaoi" when I've read over 3,000 titles and this is the first time I have been seriously so fucking lost that it's frustrated me. Most of the time I can piece things together but this one--unless they just genuinely fucked the uploads out of order or something just doesn't make any fucking sense.

Well.. Atleast you noticed this stuff. I don't really know what to say. I've just become used to it then.

I am so fucking happy that I’m not the only one that is so utterly fucking confused by this shit. Not only is the plot all over the place but there is NO EXPLANATION for ANYTHING that is going on. And then it just fucking ends out of nowhere?? Wtf I was hoping at the very least he finds out he’s like half fucking succubi and realizing that’s the reason for this random ass harem of mfs that appeared from who tf know where

I thought this was gonna be some sort of supernatural story but like none of the characters have any sort of consistency.

One minute everything is fantasy like and the next it's just your standard school setting. And it's only the main cast that is weird?

They made so many chapters for this one and now the artist is MIA so it'll never be finished. I feel like the artist didn't even know where they were going with this one if I'mma be honest here. I've tried to re-read it and take my time with it but I just-- don't understand a single goddamn thing with this kind of plot.

So to answer your first question I think mimi isn't a person, but maybe somehow a real spirit in this cursed harem world.

The best friend just likes wearing fake horns/lab coats*shut in*.

King is covered in bandages, and is seen with choke marks *w/o explanation* around his neck, because I think the operator maybe trying to put a physical fork in his path*throat*.

King's porcupine stabbed him to stop him from upsetting the operator of the harem world who is obsessed with the MC, and cursed him*the porcupine conceals themselves most of the time from the operator, probs*.

I think glasses is the manipulator/castor of the cursed harem world affect.

I believe this isn't an omegaverse, but pheromone curse might be right. Although the hearts steadily increase.

The MC probably didn't have the marks show up on visible parts until later, I'm guessing? The world is like a trap, and in a continuous loop because of the curse, I think. That's why I think everything seems to be everywhere, but with little progression, and the same scenes.

I also think "Paradise" dream, what glasses said when he is first introduced, the MC just joining the class council, MC being unable to say no, the best friend's outburst, the wounds on King, Mimi being a literal beast, the multiple hearts, glasses again being the one to rally the others up are hints.
