After Dressing up as a Peasant Girl, I Want to Get Rich Every Day

Is there any mistake? She was a palace lady, a person made of gold and jade, but she was reborn as a little village girl in a remote village. She was well-versed in all kinds of books, but... She was useless in this small mountain village, wasn't she? Her family was extremely poor. Fortunately, she had a sensible younger brother at home, so she invested in him, sent him to school, and taught him principles. He was a good boy, but he always liked to lure wolves into the house. He brought back a classmate who was eating and drinking, and he also set his sights on her. What happened? Brother: I regard you as a brother, but you want to be my brother-in-law.
