I can’t tell anyone about this matter. Although its occurrence has affected my whole life, I also want to keep this secret forever. At least in reality, thanks to the Internet world, I can talk to strangers at will Since childhood, my cousin and I are sisters. My sister is five years older than me. In my eyes, she has always been a perfect girl. My family lives in a rural suburb. I am really a girl growing up in the countryside, but I have seen the world and yearned for the life in the big city since I was a child. My sister grew up in the city, and she was born and raised in Beijing.
