Meh

I have no problems reading something cliché but here, the pacing is all wrong and the story just isn't working.
First off, we know it's a novel but we don't know any more than that. How does she know she's been reincarnated right away? How does she recognize who and what she is as a baby who had no place in the book and died in infancy?
The jumpskips are also completely useless and show case nothing. We see her being diagnosed ad weaker and smaller than average and the ML is said to look 4 years old (instead of the 1 or 2 they both are) but they look the same. The artist is not capable of creating proportions and the children just look like strange adults.
The story skips and jumps and nothing can be understood.

Also is saying the word "daddy" enough for a cold man to want to adopt you? Not to mention, a literal newborn is talking? Yeah no.
Also, everytime the father sees her, we see a superimposed picture of his late wife and daughter. It's just creepy, I first thought he saw her as an adult like his wife but then finally understood he sens her as a replacement daughter/ weak person to protect which is...not good. All in all, quite crinière.
