Song Jingyu, a 26-year-old beauty blogger, has just signed a 60-million-yuan contract. But during her celebration banquet, she accidentally falls into a river. When she opens her eyes again, she finds herself transported to the fictional Great Liang Dynasty. By an even stranger coincidence, the foolish daughter of Song Huaian, the upright magistrate of Yong'an County, who fell into the water, is also named Song Jingyu. Even the beauty mark at the corner of her left eye is exactly the same. Her new family's home is practically bare, and her honest father is so poor that they can barely afford to eat. Yet every member of the family treats her with wholehearted love. After trying countless ways to return to her own world without success, she grits her teeth and decides to make the best of her situation. With just an eyebrow pencil and a box of lip rouge, she dares to set up a little street stall. While gathering supplies, she happens to rescue a handsome man who is badly injured and unconscious. She originally intends to save him and then go her separate way, but who would have thought that once he wakes up, she won't be able to get rid of him?
