Meng Fu was 16 years old when the Jiang family came looking for her. They said that she had been mistakenly swapped with someone else since a young age. Before she can react, her body is occupied by the soul of a female journalist from an alternate world for two years.
She finally manages to reclaim her body, however…
Mother from a wealthy family: “The young master of the Tong family studied abroad, while you dropped out of high school. Although this betrothal is arranged by both families when both of you were young, there is no need to insist on the marriage.”
Father: “Xinran is also my daughter. I hope you will get along well with her and learn from her.”
Younger brother: “I only have one elder sister, and she is Jiang Xinran.”
Before reclaiming her body, Meng Fu was ranked fourth in the Global Idol girl group program. She was a bimbo that all netizens hated, and the daughter that the Jiang family refused to recognize. However, after she reclaims her body, no offence, but no other contestant is a match for her.
Initially, fans from major forums insist that Meng Fu leaves the girl group and showbiz, attacking her with harsh criticisms. A group of fans retaliate and speak up for Meng Fu.
Until later, a powerful figure publishes a post: [Reposting my new drama]
