Review Detail of Yumbrella in A Villainess Should Be Strong

Um, so I am very new to reviewing so apologies in advance if my review is confusing or annoying...By the way, read the full review since the good stuff is mentioned in end... So, first of all, I would like to say that I really absolutely loved reading this novel till 100 chapters and after that, it started to go downhill a lot... okay so moving on to writing quality at first, I have noticed a few mistakes on character's names being misplaced or some spacing errors which had been a little bit annoying but overall I don't feel it has lots of mistakes grammatically but since it isn't exactly errorless I can't give 4.5 stars hence 4 stars... now as far as stability of updates is concerned, it shows the last chapter was released months ago? (maybe I'm wrong and I'm really new to webnovel platform) but I won't complain more about this since I was binge reading this novel Story development..this is what I found extremely disappointing. To be fair I had extremely high expectations for this novel. There were some really bad plotholes right from the beginning(hey can a five-year-old can talk like a normal adult, do superhero stuff and her parents would just be a little bit weirded out not actually questioning her or anything) but I assumed they can be possible in the fantasy genre. But somewhere along the 80th to 100th chapter the story started to go awry. extremely sharp changes in themes and settings without a sense of fluidity. almost as if there hasn't been proper planning in its execution. In my opinion, most of the recent plot seems forced. But I will never say it's all bad. there had been some extremely awesome moments that I have never experienced before. I really believe that this novel still hasn't lost its potential and its storyline seems to be getting better as of the 160th chapter onwards? Now I have mixed feelings for character designs. I REALLY REALLY adored the child Estelle in the beginning. But I stopped adoring Estelle and rather started empathizing/pitying with her in the later chapter. I actually loved how her character developed from the beginning till now. Now the other characters also seem to have their own specific traits and characters BUT it's extremely disappointing that some of the characters just get forgotten when I least expected it (welp alan and Noah...). Now the world background...Actually, it's too complicated for me to review. If the author is a high schooler, I say she/he is a genius. You actually made the whole world stuff and magic into a logic which is absolutely brilliant. And I appreciate the huge amount of care you tried putting into the world background but to be honest, in the end, I was just confused to death... and the underworld was nearly forgotten and I guess it would change in upcoming chapters? Now, why do I find this novel stellar? well because it's a gem in itself. To those who have read the first 50 chapters and whines that nowhere Estelle being villainess is shown, the only advice I can give you is that please read the novel completely before whining. The concept is entirely new in itself and to those who are looking for a villainess snatching the crown prince from the heroine of otome novel, you are officially scammed. I loved this novel where the heroine is bold and courageous instead of a wallflower and thank god there is no dumb romance. All in all, I would say try this novel, perhaps your initial expectations from reading the first few chapters of this novel won't be fulfilled by the end but this novel is indeed one of the best novels with a bold female protagonist. Author-san, I hope you don't drop this novel, obviously, I have been harsh on my review but that's because I still feel that this novel is really unique and interesting and that you are really growing as an author since the last few chapters have been getting better. Bye and thanks for patiently reading this!
