Shocking Gunfire, Cousin Disappeared into the Woods

[Completed] I, Yun Shu, was preparing for the exam in my senior year of high school. I accidentally broke into the shocking conspiracy of my cousin Yun Yue - she actually wanted to join forces with her cousin to create an accident to defraud her aunt! I kept my concerns to myself, but in just three days, my aunt really encountered a strange car accident! My cousin was squandering the family's wealth and power. She had a big argument with me late at night and rushed out of the door, only to be locked by the bright light of a helicopter! A gunshot pierced the night sky, leaving only a pool of fresh blood in the woods. My cousin, who I had been fighting with since childhood, completely disappeared from the world. My whole family was angry with my neighbor's sister. My friendship with my childhood best friend broke down, and I was filled with fear and guilt. It wasn't until I plucked up the courage to ask for the truth that I learned the secret that pierced the Three Views: My sister hid it from everyone and had a cruel and dangerous boyfriend. She has already been involved in a fatal whirlpool! Helicopters, gunfire, disappearances, blood pools... Behind all the strange events, there is a darkness that I can't even imagine. While I was studying hard for the college entrance examination, I was frantically searching for my sister's whereabouts. This time, I must find her and protect my family!
