The author used the "genius at birth" troupe to describe how she was very smart at birth, she could walk and talk at 6 months old (just a few words don't worry, not a freak) BUT, the way it was portrait as if she can understand everything and still act like whatever she wanted its making her seem a a huge brat. Author made her able to walk and talk only to sneak into her moms room to undress her and breastfeed (maybe not big issue again, not a mom, but I would find it creepy), the way it was described as ML its VERY tired and could not even open her eyes while someone entered her room and took advantage... no thanks. No me like it!!! Also I don't know how just in her case she never sounds like a child no matter what. Somehow its like her only role in the novel was to introduce the abortion policy, she never sounded right age like her brother, she is speaking like an auntie when she scolds people, she is portrait as greedy when ML got a piece of jewellery and she immediately wanted to take it (author even mentioned she has gold, jade and precious stones, while parading a dress imported costing more than regular people salary... 6 YEARS OLD CHILD remember!!!) At the end ends up copying brothers carrier choice while being prized for knowing "psychology" because she finally wrote a book for children after being tutored by brother who wrote articles for magazines for like 9 years...
