A Peasant Widow Escapes Poverty and Becomes Rich

As soon as she traveled through time, she became a widow who killed her husband. It was enough that such a bloody plot could happen to her! Being in a remote rural area, extremely poor, and with a mother-in-law who is always deliberately making things difficult for her, this character is too miserable. But fortunately, as a member of the time-traveling army, there is space as a reward. Of course she didn't run away after getting rich, but she was a widow, so why were so many people coming to ask for her hand in marriage?
