Half-life widow, husband turns out alive

In the ancient capital of Shengjing, the third wife of the Marquis of Jing'an managed the household with impeccable order. Originally the daughter of a high-ranking official, Wei Mian was betrothed to the Marquis of Jing'an at the age of sixteen by her parents' arrangement. She had expected a prosperous and well-matched marriage, but tragically, her husband, Xie Zi'an, was killed in battle just days after their wedding and disappeared without a trace. To her dismay, at the end of her uneventful life, Wei Mian unexpectedly learned that her deceased husband was not only alive but had also taken another wife in a secluded paradise, living a carefree life surrounded by children and grandchildren. Even more tragically, everyone in the household knew about this, except for her, the legal wife.
