After Being Reborn, I Adopted My Enemy's Daughter

In order to settle down and buy a house, my sister's best friend proposed to have a fake marriage with her brother-in-law. I objected strenuously. But my sister happily said that she was my best friend since childhood, and I believed her. Later, my best friend and brother-in-law made a fake show and wanted to take away all my sister's property, so they pushed her down from a dozen floors. I refused to give up, and when I was running around to appeal for my sister, I was hit and killed by those two people with a malicious car. Open your eyes again. Sister, just be happy.
