After Learning the Ending, I Gave Up on Revenge

In her previous life, her entire family was slaughtered, and she endured humiliation for ten years as she plotted revenge. In the end, she succeeded in taking her enemies down with her. But the result was a kingdom in turmoil, innocent people dead, and all her remaining loyal followers buried alongside her. Though she had avenged her blood feud, everything ended in utter ruin, with no one finding peace. Reborn, she chose not to walk the same road of revenge again. She abandoned her hatred completely. She would no longer target her enemies, plan assassinations, or stir up the court. All she wanted was to protect her loved ones, root out the mastermind behind it all, escape with her life, and reclaim everything that was hers, so she could have a happy ending instead.
