Synopsis: Lin Wanxi, the legitimate daughter of the Marquis of Weiyuan's household, was betrothed at her mother's command to Xiao Yichen, the young master of a general's family. On their wedding day, an urgent report arrived from the northern frontier: the Northern Di had invaded. Xiao Yichen was ordered to lead troops to the rescue, and he would be gone for three years. At home, Lin Wanxi dutifully served her parents-in-law and got along harmoniously with her relatives. What she looked forward to with all her heart was not wealth or power, but the simple happiness of sharing life's journey with her husband. In the end, however, what awaited her was not a blissful marriage of mutual respect, but an order to divorce, along with the catastrophic ruin of the entire Marquis of Weiyuan's household: execution for all and exile to the frontier.
