sad to see the MC getting progressively dumber as the chapters go by and recurring to Deus Ex Machina Mcguffins whenever she's in any sort of bind. Somehow the author made her really smart because she was 24 before she died, but never once realized that a little petty child was manipulating her, aside from never receiving any sort of formal education? And it took her less than a year to reach her potential, which is being a fucking genius, mind you. Okay. Honestly, she's the most complex character I've seen in any of these shoujo manhwas. She's actually ill-natured, but it's hard to dislike her because you feel that all the bad things she does are somewhat justified, and honestly, despite what it is stated that she did in her original timeline, what it is actually shown that she does is comparable to playing some mean pranks, to be honest.
The romance is okay, the prince is an annoying sociopath, but he's hot, so everything's forgiven apparently. I mean, this doesn't really need a forced romance – although I've seen much worse – but I guess it wouldn't be appealing to girls if it didn't have hot anime dudes.
