Reborn in the 1970s: I Turn My Life Around by Raising Pigs

Because she was a girl, her parents gave her away as soon as she was born. Her adoptive parents cherished her like a treasure, and for the sake of her future, they were even willing to reunite her with her birth parents. Once they realized she was grown and could be useful to them, her birth parents did everything they could to win her over, driving a wedge between her and her adoptive parents and leading to her being schemed against and killed by a scumbag and her own sister. Reborn, she’ll repay every debt and return every kindness. She’ll also lead a group of reliable villagers in raising pigs and planting trees to build a better life. Wait, wasn’t that guy next door to her adoptive parents’ house a major villain in her past life? How did she end up marrying the villain?
