On her wedding day, Shen Ruojin, the daughter of a military family, was betrayed when her fiancé, Pei Jing, eloped with her half-sister. In front of all the guests, she resolutely chose to marry Qin Lang, the notorious playboy of the capital. No one knew that Shen Ruojin had been reborn, carrying memories of her past life, when her family and lover betrayed her and she ultimately lost everything. She had planned to set three conditions with Qin Lang and divorce him a year later, but she unexpectedly discovered that her seemingly debauched husband was far more than he appeared. Not only did he step forward when she was in danger, he also devised strategies behind the scenes as she fought on the battlefield. When Shen Ruojin tried to honor their agreement to divorce, Qin Lang placed the military tally and imperial seal in her hands, vowing to help her claim the realm. Amid the chaos of war, the once-mocked couple stood together: one defended the nation’s borders with a spear, the other wielded power to shape the court. Together, they forged a legend: “Spring runs deep behind embroidered curtains, and the realm is yours.”
