The writing is engaging and the overarching plot of the kingdom being threatened by an evil sorcerer king is very classic fairytale
The whole thing is set up like the origin story for an Isekai heroine, and Mabel is cute and clever enough to keep it moving.
However, I can tell you aren't actually asking me these things and are instead defaulting to what an Engliah teacher would ask about some frivolous reading passage. So let me ask you, what is it that you desire when reading manwha? Why were your expectations so high here?

Uhm... have you really read this manhwa? Because most of the things you said doesn't even make sense aside from the fact that you're a hater. For someone who said that they have high expectations because they read since a kid, this came up as an inauthentic take of a pretty great story. As someone who already read and reread the novel of this manhwa, I can say that this has an amazing and interesting plot and that the manhwa is still nowhere near the clinax part of the story. It might be that you just saw a few first panels of this manhwa and decided that this is one of those "harem" manhwas (when its not). The only thing I can agree with your comment is the "Mary Sue" MC and that you're a hater. The rest is complete misinformation and misinterpretation. Well, suit yourself.
Can we stop popularising Mary Sue Manhwa where it's clear the author is projecting a need to be loved and adored onto their work? I sound cruel, but like the way it's done is SOOO BADD if she wasn't grown and in the body of a baby, like if she were quite littersly just a baby it would be been okay. if she was grown and in the body of a baby, but actually acted her age, genuinely did something to earn the unparalleled adoration she receives and did shit herself instead of being a whiney bitch then that would also be okay. Dare I say that would be peak. But all she does is breathe and the whole world falls apart bending to her will so it makes the story feel incredibly shallow. Not to mention it's just really like idk how to say it, but this genre is the female equivalent of shitty harem isekais. Idk if that applies to this manhwa, but with this genre it's always a grown woman in the body of a baby and every male in the world is in love with her. Always a father, grandfather, brothers, uncles, male friends, all these powerful attractive men and maybe 1 or 2 token female characters, typically a maid or an insignificant girl who's on her side. Female influence? Never heard of her, cos every woman in the world is out to get the MC cos she's so perfect! And they're do jealous! Not to mention all ugly men are evil for some reason, and every girl that's nearly as pretty as the MC/receives male attention is evil??! This is really poorly structured cos idk how to word my opinion, but pls I beg you go watch a mattybites video or 2 and open your eyes to how garbage this is. It's a non issue ik I'm js a hater
