I Will Protect You in This Life

My name is Li Wen, 21 years old. I just graduated from college and am going to study in the United States. ✏But my father is a drunk person who drinks all day long ✏I hate the way he usually acts drunk and crazy when he is drunk ✏That bastard father killed his mother once, and her mother died in a car accident. And I will give up studying abroad and come to S city to protect her... My bastard father didn't expect to treat my sister and me even more viciously...
