Xie Qingwei spent her life with Zhuang Fanzhou, the prime minister, believing theirs was a destined love that grew quietly over time. Reborn on the day she came of age and was to choose a husband, she eagerly hoped to make up for her regrets, only to discover that Zhuang Fanzhou had also returned with memories of his past life and now intended to marry her younger half-sister instead. Realizing that decades of devotion had been misplaced, Xie Qingwei cuts off her old love and resolutely marries the frail, short-lived heir of the Prince of Yongnan. Little does she know that this aloof heir is the longtime confidant with whom she has shared a deep bond through poetry and calligraphy. He gives her exclusive love and freedom, accompanying her as she breaks free from worldly constraints and travels across mountains and rivers.
