Review Detail of laurelis in The Fake Daughter Is Not Innocent

I'm at chapter 83 and up to now the synopsis is really different of what the novel is actually about. In the synopsis MC is the "weapon" of the ML because of her talents. There is nothing about that in the novel. In fact, she becomes the little sister of the ML, and the ML doesn't use her talents at all. Moreover, at one time in the novel we have a ten year old MC then suddenly she is in university. The time leap is not smooth at all because there are many unresolved matters. Plus the sexualisation of children by the author made things ten times worse.
