After Rebirth, I Became Everyone's Pawn

She was killed by her whole family when she was eighteen years old. After her rebirth, she smiled. Fiancé wants her money? Send him bankrupt. Sister wants her identity? Send her to jail. Best friend wants her man? Send her to death. She cleaned them up one by one until she found—— The cold CEO she had hated all her life died for her in her previous life. The sister she sent to prison with her own hands had the same blood as her. It turns out that everyone's approach is a scam that has been planned for twenty years. This time, she asked everyone to kneel down and spit out twice as much of what they had eaten.
