Modern ALS patient Shen Ning accidentally travels into a book, becoming a heavily criticized cannon-fodder widow in the story. With her late husband passing away, she is left with her poisoned and mentally unclear brother-in-law, Xiao Nanchen. The original owner blindly groveled to scholar Pei Yuanzhou and was continuously exploited by her biological family, suffering all sorts of disdain from those around her. After her rebirth, Shen Ning completely rids herself of her lovestruck mindset, relying on modern knowledge to make sugar and canned goods, building a fragrance and cosmetics trading house, and striving to build her career and make money. While dealing with greedy relatives, insidious rivals, and scandalous rumors, she also looks after her brother-in-law whose true identity conceals a mystery. The two become intertwined and accompany one another, as Shen Ning breaks free from the shackles of fate, transforming from an abused rural widow into an independent businesswoman.
