First of all, this heroine is denser than a neutron star. It takes her 77 chapters to acknowledge that the creepy, obsessive, bordering on yandere male lead is in love with her. There's 91 chapters total. Speaking of, the male lead starts out pretty creepy (which is unfortunately kind of normal for this genre), but he's given a bit of justification and he loosens up a little later on. He is of course the usual Perfect Boy in every other respect.
I'd say this is more on the political intrigue end of things, the romance here is either predecided (the main couple) or it just kind of happens and everyone accepts it. This would be fine, except the setting is pretty barebones and while there is a pretty varied cast of characters (so long as you're okay with 90% of them being bishounens), including, somehow, a pretty well done sibling relationship between the heroine and another reincarnator, ultimately nothing really happens with them. The crown prince is a patrick bateman-esque psychopath who just..... does bad things arbitrarily (part of this is due to the ML having foreknowledge of his plan and just kinda dealing with everything perfectly) and then gets taken down anticlimactically.
It's a shame for me since I quite liked the design and personality of this heroine (although she is still, very dense) and it's somewhat rare to see a work with multiple couples. The side characters get to shine occasionally (the Boys planning the ML's engagement strategy was pretty good) but that's pretty much all they get. Despite being 91 chapters, the story feels kind of rushed at the end, with the first real conflict between the forces of the ML and crown prince also being essentially the last conflict.
The last issue I had was with how the main romance progressed, which is a literal magic spell that involves telling your beloved how much you love them. Look. I get that I'm a fan of this genre and this kind of thing is super popular. However, making that the moment when your heroine realizes that, she may, in fact, be in love with the ML (this is after 77 chapters of her brushing him off btw) feels really cheap. To clarify, the conditions are that the recovery spell will only work if the caster (ML) feels true love for the person they're casting it on. I would have genuinely been more ok with her rationalizing this away like she did for literally everything else he did while she was conscious, but this is apparently the big moment where everything clicks into place for her. Like, I've heard of some contrived setups for a first meeting or a twist to keep the main couple together but I've never heard of a contrived setup for the big confession. I suppose it's at least unique in that sense.
