I Reborn to Crush All Backstabbers

A student named Camila accused Elena's father of assault. The accusation was false but the pressure was public and total, and he went off a building. Elena watched it happen. Afterward the three young people her father had housed and paid for turned on her, and she was killed. Elena wakes up years earlier with all of it still in her head. She goes at Camila first, and this time she has security recordings and a medical record proving her father could not have fathered a child, and she puts both in front of everyone Camila performed for. Then she moves the family savings somewhere the three cannot reach, and when the money stops arriving they show what they are, going as far as breaking into her room at night. They want the experiment data her father left behind, and they come at her with a weapon to get it. Elena lets them think it is working and sets the trap so the man giving them orders, a man named Adrian, has to step out where she can reach him.
