Yu Zhaoning spent three years in the Marquis of Jing'an's household, pouring her best years, medical skills, and dowry into the family. She treated her mother-in-law's chronic illness, managed the accounts and covered her husband Pei Jingchuan's losses, and maintained the marquis household's trade routes and connections. Everyone took her devotion for granted and assumed she would never leave. Until Yan Qingrou, Pei Jingchuan's long-lost white moonlight, returned to the capital. She moved into Yu Zhaoning's courtyard, took the medicine left by her mother, and claimed the place that should have been hers. The cruelest time, Pei Jingchuan forcibly took Yu Zhaoning's only Vitality-Guarding Pill to save Yan Qingrou. Yu Zhaoning's pregnancy was already unstable, and that night she lost the child her husband had never even known about. The next day, she didn't cry or make a scene. She simply placed the divorce papers in front of Pei Jingchuan. "Give her the medicine, and give her you, too." Everyone waited for her to come crawling back. But instead, she reclaimed her dowry, prescriptions, and businesses, and started over at an unremarkable little pharmacy. She saved women in childbirth, exposed fake medicine, and brought epidemics under control. Little by little, she also uncovered the old military-medicine case behind her parents' supposed "accidental deaths." Meanwhile, Xiao Chengyuan, the cold-faced regent whom she had saved by chance, gradually realized that this woman didn't need anyone to live her life for her. All she needed was someone who respected her choices. Later, Pei Jingchuan finally got his wish and married Yan Qingrou. The whole city waited to see Yu Zhaoning humiliated. Yet on that very day, the regent's wedding procession swept down the main street, its ten miles of bridal finery outshining the marquis household's wedding sedan. Pei Jingchuan lifted the carriage curtain and saw Yu Zhaoning pass before him, crowned as a bride.
