The youngest daughter, Su Wan, was in her boudoir posting happy words to her sister who was about to get married one second, and the next second her sister pushed her into a sedan chair to marry her to a deceased husband she had never met. I never thought that marrying into the Gu family on behalf of my sister who had escaped from marriage would be the fault of my sister-in-law Lin Yan. The sister-in-law of this business owner was able to calculate every cent in the account book and protect my dignity as the "widow of my late husband". Even the warmth of her fingertips grazing my wrist when she was blocking my drink made my heart skip a beat. It was not until later that I found out that my sister was not afraid of marrying her old friend when she ran away from marriage, but because she had long realized that there was something hidden behind the death of her "husband". Now I am following my sister-in-law to search for clues, watching her concentration on comparing handwriting under the candlelight, and suddenly I am not afraid of the undercurrent of the Gu family - as long as I can be with her, even if it means unraveling a huge mystery, I am willing to do so.
Concept: Female mutual aid and emotional connection: Su Wan and Lin Yan, one is a "widow" who was forced to marry, and the other is a smart and capable head sister-in-law in the family. In the process of jointly exploring the truth, they support and protect each other, showing the deep emotional connection and mutual help between women, breaking the stereotype of women competing against each other in traditional house fights.
