I just finished the raws. So possible spoilers, but not really.
This was pretty good at the beginning. I like how she was the fake daughter and the real daughter was the stereotypical cold, cool, golden finger chick. The protag has a decent personality, which is good. Then she gets a system. Some people didn't like that, but it really didn't affect the plot... until it disappeared. As in, I forgot there was a system until a random part in the middle and at the very end. At some point, she starts to show off the ancient martial arts she knew from her previous life apparently. Around ch. 1000 there is a completely random plot arc that didn't need to be there. It also got to the point halfway through the book where I skipped all the web comments. Sometimes there are CHAPTERS of nonsense that don't help develop the plot at all. Even describing the movie she took part in takes a chapter or two, but then it doesn't matter anymore after that. I had to force myself to finish this.
overall, if you want a cute, mindless book, this is a good choice.
