Su Lin, the protagonist, was once a top-tier female sommelier with a brilliant future. But after her family's restaurant went bankrupt, she was saddled with enormous debts and had no choice but to join a state-owned institution known for its strict work culture and tangled personal relationships. In this completely unfamiliar world of officialdom, Su Lin stood out like a sore thumb. People saw her as a pretty face with no connections and no sense of the rules. But she soon discovered that the wine-tasting skills she'd honed over the years, judging a wine's vintage, origin, potential, and flaws by observing its color, smelling its aroma, and tasting it, could be applied just as effectively to understanding people and workplace relationships.
