The story was really sad. It was a female protagonist who was basically the sword for the emperor (or something else, I kinda forgot). Basically she’s super OP with the sword and all. She also was called a murderer by the nobles because she would always be sent to the battlefield and all. She gets a second chance after she is killed by the emperor or the nobles. I remember this part where she was badly beaten until she was disfigured by this man. She couldn’t retaliate and it was so sad. I don’t think she did anything to him once she goes back in time. I think present timeline she decides to live differently. Like not be the emperors sword or something. There was also this woman who was involved in her demise. I don’t remember much about her. If you think you know, please help me.
