The modern woman Su Wanqing traveled through time and became the daughter of a minister of household affairs, trying to conquer Prince Yi Hongxiao using the modern view of marriage and love of "one person for life." However, she was criticized in front of the original author when she recited poems, was suppressed by the royal chef when she was engaged in gourmet food, and tried to kill Ji Xiaolan but was counterattacked. After being completely exposed, Ji Xiaolan did not burn her to death, but gave her a new choice - to open a "best friend agency" to deal with all kinds of dissatisfaction for the thousands of women trapped in the back houses of the Qing Dynasty.
