The beginning of the story from what I remembered is Lippe's entire family getting killed and she was the last. Then by the power of something, she was brought back to the past with her memories of that life, enabling her to change the future.
It's fine if some characters swoon at her cuteness and her 'genius' but for all of them to do that is baffling. If this manhwa presented itself more as a comedy then I would not have a problem. However, it didn't give that impression. I was expecting a more, for lack of better words, plotting and manipulative MC, being analytical of the people around her and how she'll use her past knowledge to help people or gain an upper hand.
I think what bothers me is that everyone is striving to be better because Lippe randomly said some wise words for her age and is cute. It doesn't feel like she herself is actively making the change and it feels so easy. I do understand that something like that happens, she's doing something so there is some effect. It just comes off as convenient to me and, I'm sorry for my words, incredibly stupid the way her family reacts.
It really is progressing slow and as much as I enjoy the detail on these scenes to show how Lippe is changing the future, I think all this could be accomplished if she returned to her 4 or 5 year old self. And it wouldn't be weird how she could speak full sentences.
