After being reborn as a widow, she holds the supermarket space

Gawain had a miserable life in his previous life, but he was lucky enough to be reborn, only to be reborn into an era of food and clothing shortages, and to have a vicious widowed sister-in-law.
It would have been fine if she had gone from being a girl who had never been in love to a widowed young woman, but as soon as she showed up, she found herself at the scene where the original owner had failed in an affair and was murdered.
This is too sad.
What's even more tragic is that she not only has a brother-in-law and sister-in-law, but also a whole family to support.
There is also her brother from her mother's side, and her parents who favor boys over girls, who want her to be a brother-supporting demon.
A bad reputation and a burdensome in-laws are absolutely unacceptable.
In order to live a good life, she is determined not to give up.
In her previous life, she was crushed to death by supermarket shelves, but in this life, the supermarket actually came with her!
With the support of supermarkets, do you still have to worry about food and drink? Not only do you not have to worry, you can also sell your food and exchange it for cash, making a fortune.
Small vendors, open shops, large supermarkets, chain stores, listed companies...
Let’s see how Gao Wen gradually becomes rich, raises his younger siblings, and trains college students.
But how come she didn't realize that there was always someone by her side who silently protected her, worked hard with her, and supported the family?
