"Su Nianyi was once an ace fighter pilot. Now she flies undercover as a flight attendant, nursing a decade-long secret crush on Captain Ling Yunche—until a misunderstanding over his “first love” drives her away. When a mission calls, she trades one disguise for another: posing as a wealthy heiress engaged to the heir of Yin Airlines, a company suspected of treason. For one year, Ling Yunche searches for her, desperate and unaware. Then he returns—not as a captain, but as “Yun Xiao,” a covert operative. His mission: infiltrate the same conspiracy she’s already deep inside. Her codename: “Yun Yao.” Together, they uncover a plot that reaches beyond the Yin family—a conspiracy trafficking aviation secrets to foreign powers. In the process, they unravel the truth behind the misunderstanding that tore them apart. When the dust settles, the Yins fall, Shen Jiaxue faces justice, and two operatives finally shed their masks—for each other. A story of love forged in the shadows, and the flight path that brought them home."
