Could It Be That My Sister Has Also Been Reborn?

In my previous life, my sister was in love. For her first love, she asked me to marry her to a blind date arranged by my family. I accompanied him from the rental house to the big villa. But my sister's first love changed her mind not long after they got married. She got disfigured in a car accident after being drunk, and she never recovered. She would drink and play games at home every day, and she would always hit and scold her. In the end, the first love held a grudge and sneaked into the house in the middle of the night and deliberately turned on the gas, causing our family to never wake up.
