Rebirth No Longer Prevents My Cousin from Marrying a Domestically Violent Boyfriend

I tried my best to prevent my cousin from marrying my ex-boyfriend who had domestically abused me. But she cruelly stabbed me to death in front of my mother. Even if my mother knelt down and begged her, she couldn't get any mercy from her. She blamed all her misfortunes on me. I can't close my eyes until I die. When I opened my eyes and went back to that day, I only said to her: "You are a match made in heaven!"
