Hidden for eight years, the youth Pei Shuo rises from the dust and walks into the most noble Grand Princess's mansion with a cynical appearance. Facing the turbulent imperial court and her lofty presence, he handles every move with street-smart wisdom and extraordinary courage, resolving crisis after crisis with casual conversations. The world mocks him for relying on the powerful, but time and again he proves his sincerity through his actions—speaking up for the vulnerable, clearing the names of the loyal, and blocking the undercurrents for the country. When the sealed old case and the powerful ministers' conspiracy are uncovered together, he helps the Grand Princess steady the realm and restores his own background to clarity. After the wind and snow, he not only wins back his dignity, but also wins a confidante willing to guard the rivers and mountains with him.
