After being flogged to death for a crime she didn’t commit, Calista received a second chance when a system contracted her. It was simple: complete tasks and she could earn a second chance in life. After completing several of them, the chance to reincarnate in her original world and body was finally granted to her.However, unlike others, she didn’t want revenge against the people who killed her or wanted to unmask what truly transpired back then. All she wanted was to live peacefully and enjoy the bounty benefits which came with the reincarnation.And that was something she found when she met a man she fell in love with in some backward village. Unfortunately, all that was broken when her husband of five years perished at the hands of bandits.Things went downhill when Calista married her second husband, Orson, an amnesiac man whom she scammed into marrying her.

If he knew she was still alive, he might kill her again.That meant that this time, Calista might have to strike first.
