I have been an only child for 16 years and I really didn't expect that one day I would have a sister. To be honest, I was just a slut that I could see everywhere, and I had a little bit of a girl. But I really didn't expect that one day I actually had a sister, my mother finally remarried and found a new man. I met at work, that is, my new father, but he already had a child, a girl, named Ran Ping, and was only a few months younger than me, so she naturally became my half-sister. We were arranged to go to school in the same class in the same school, and her room was next to my room, both on the second floor
