Oops! The Phony Princess Wins Again!

Su Nian'an's father runs an international finance group, her mother is an actress, and her older brother is treated as a prodigy. She is the ordinary one, and she settled early on into doing as little as possible. Then Du Ruoqing arrives claiming to be the family's real daughter, and a DNA test is ordered. While the results are pending, Du Ruoqing has Su Nian'an put out of the house. Su Nian'an packs without arguing. Du Ruoqing keeps pushing, taking on more and going further to prove which of them belongs, and the household staff and the family drift toward the girl who asks for nothing. Su Nian'an watches her go, and the less she does, the better things turn out for her.
