Born on the same day, hour, and minute, Luo Mengmeng and Gu Zhihan were betrothed before their first breath. What began as parental arrangement became something neither could escape. As a toddler, Mengmeng would lisp, "Husband, marry me?" only to have Gu Zhihan wrinkle his nose in disgust. Years later, he'd corner her with a dangerous smile, murmuring, "Marriage is affordable now. Let me buy you one." From their first cry through kindergarten, primary school, adolescence, and into university, they remained inseparable. A shared timeline of growth, from infancy to adulthood, where devotion deepened with every stage of life.
