* **Era Background:** The fictional dynasty "Dajing" is prosperous on the surface, but in fact the imperial power is falling apart, vassal kings are divided, conflicts between aristocratic families and poor families, civil servants and military generals are intertwined, and the undercurrent is turbulent.
* **Heroine: Shen Weiwan** - It turns out that after Zhongliang, her father was falsely accused of treason and his entire family was executed. She was lucky enough to be rescued by a loyal servant. She kept her name anonymous and took the pseudonym "Awan". She lurked in the "Tingfeng Garden", a music studio at the bottom of the capital, and became an inconspicuous musician. She is smart and tolerant, proficient in music (actually a family skill, a secret code transmission method), and also understands the treacherous nature of people's hearts, waiting for opportunities to reverse the family's case.
* **Male Protagonist: Xiao Che** - The seventh prince of Dajing. His mother and concubine died young and he was of low birth. On the surface, he was an idle prince who wandered around the market, did not care about political affairs, and even indulged in wine and sex. He was known as "Qi Lang". In fact, he has a deep mind and amazing insight. He secretly cultivates power and works step by step, intending to find hope in the turbulent battle for inheritance and to find out the old case that was widely implicated (secretly related to the Shen family case).
* **Core of Machiavellian Strategy:** It revolves around the succession of the throne, involving the open and secret struggles between princes, the game between aristocratic families and imperial power, the entanglement of border troubles and internal affairs, and the truth of old cases many years ago.
* **Romance core:** Shen Weiwan and Xiao Che went from testing and using each other to gradually discovering each other's disguised sincerity and ambition. In a crisis-ridden environment, they developed a sweet and dangerous relationship, becoming each other's only comfort and reliance.
