Song Liangyin, the daughter of a treacherous chancellor, returns to the capital with her child. She originally plans to make enough money to leave with her child and live far away, but unexpectedly runs into her old adversary, Lan Wuyu. Four years ago, the two shared a brief entanglement before going their separate ways. Four years later, he has become a cool and reserved powerful official, while she remains full of twisted logic and clever schemes to make money. One cautiously tests the waters at every turn, while the other looks for every opportunity to escape. Yet the mystery surrounding the child's parentage makes this reunion impossible to end easily. Their old feelings remain unresolved, and political undercurrents are stirring. Gradually, she discovers that this seemingly antagonistic Vice Minister harbors far deeper feelings and intentions than she ever imagined.
