TL;DR: there's definitely better QT novels out there though at least this one never actually went the whole pseudo-rape route (#forever bitter about Perfect Destiny and others like it). Each world is brief and it's hit or miss if the face-slapping is even a focus of the world, and the yandere ML is pretty much instantly in love so there's no actual romance development either.

This was actually my second read through of most of the book, since I held off while waiting for the last two arcs to be finished for full re-read and... man, I have regrets. So many regrets. There was clearly a lot I'd forgotten about this book and maybe reading it arc by arc meant I had a better tolerance for the shenanigans that were going on in it but... thinking about it, probably not.

It didn't start off the worst, though the ML is the pretty typical yandere who falls in love almost instantly and spends the rest of the time trying to force a relationship with the MC if he initially isn't on board with it. This becomes increasingly tiresome when MC stops being so coldly distant and starts becoming as obsessively interested in the ML. This story legit reaches the point where MC goes into the next world, immediately finds the ML, and throws himself at him with no preamble, and the ML (who's character settings are almost always coldly distant, cruel, ruthless, etc) immediately folds like a wet paper towel and obsessively dotes on this complete stranger. The second-to-last arc, the Interstellar one, was by far and large the worst example.

Anyway, my point is it was boring to read. Each world was very short so the plot development was minimal, with stereotypical face-slapping happening around a romance that... wasn't terribly interesting. The book made some claims at one point about how the MC had to pursue the ML in every world and I wanted to laugh because that was a shame-faced lie. The ML was either the pursuer or he was instantly indulgently in love with the MC so to call anything he did a "pursuit" was a joke.

Also, I straight up skipped two arcs. I read the last chapter or two, just to get the overarching plot bits, and moved right the hell on. More details in the below content warning lines. Anyway, the last arc was moderately more interesting than the previous couple of arcs but it still felt like something of an abrupt ending

and then to find out that the entire creation of the seventh realm was essentially pointless since the MC didn't give a crap about it was... a choice.
