I am a high school girl, my mother died young, my father and brother love me very much, especially my brother, he always pities me, sometimes I even feel that my brother's love for me has gone beyond the love between brother and sister, but between man and woman, but he is my brother... I offended a female gangster in school, she warned me to be careful, hum, am I afraid of you? However, on my way home from evening self-study, I was stopped by some stinky gangsters who wanted to bully me. My head suddenly hurt, white light flashed in front of my eyes, and I lost consciousness. When I woke up and found myself lying on the bed in my room, I had no memory of what had happened. When I returned to school, I heard that the gangsters who wanted to bully me yesterday were dead on the street. Who killed them? The senior who is one grade above me said that he and I are from the same race and are destined to be together. Oh my God, what am I?
