After My Mother Was Reborn, She Took Her Bad Sister Away

My mother was reborn on the day she divorced my father. This time, she just glanced at me with disgust, turned around and held her sister's hand with a smile: "Xinxin, how about living with your mother? Mom will definitely train you well and let your father take your idiot sister away!" She happily took my sister away, looking forward to living a noble life with her sister. Unfortunately, she doesn't know that my sister is a highly intelligent sadist.
