Description This is a live‑action interactive drama set within the glamorous urban high‑society elite, where a grand tale of revenge and political intrigue spanning three corporations unfolds.

Ji Xiaoxue, the heiress of the Su Group, lost her entire family to the Gu clan. With the help of her best friend Xia Wanqing, she devises and executes counterattacks against the Gu family, ultimately reclaiming her family’s company and fortune.

Xia Wanqing, the sole daughter of the Xia Group and Ji Xiaoxue’s closest friend, infiltrates the Gu household under the guise of a political marriage. Working in secret tandem with Ji Xiaoxue, she navigates between the two Gu brothers to gather intelligence and sow division, advancing Ji Xiaoxue’s revenge scheme.

Gu Chengyan is utterly self‑serving and will manipulate anything for profit. His goal is to seize family assets and uncover the true intentions of Ji Xiaoxue and Xia Wanqing.

Gu Chenjing conspires alongside his mother against Gu Chengyan. He hires Ji Xiaoxue merely as a pawn in his bid to seize control of the Gu family’s wealth.
Once, the Su Group was ruined through persecution by the Gu family. Surviving heir Ji Xiaoxue lives under an assumed name, scraping by with multiple odd‑jobs while secretly plotting her vengeance. Her confidante Xia Wanqing penetrates deep into Gu family circles as the eldest son’s fiancée and the Xia family heiress. She feigns affection toward the two Gu brothers, gathering intelligence and stoking internal strife, coordinating covertly with Ji Xiaoxue to carry out their revenge.
The Gu household is rife with internal conflict. Gu Chengyan, the group’s leader, was left paralyzed after a car accident and blinded by his younger brother’s treachery. Paranoid and ruthless, he clings tightly to family property, sees through the women’s schemes and works to counter their plots. The seemingly easy‑going second‑born son Gu Chenjing harbors immense ambition. Together with his mother he covets power, forms an alliance with Xia Wanqing, and uses Ji Xiaoxue as a tool for his own power grab, constantly shifting allegiance among competing factions.
