I Am Not "I"

My name is Chu Heling, I am 22 years old. Since that accidental fall, I have lost all memory. My origin and past are like a piece of white paper that can be scribbled on by others. It has been written on and forced upon me, but I can only accept it in full. On my birthday, I met "my" sister for the first time, and she came to give "me" a gift. The moment she saw me, she was stunned, and the gift she was holding in her hands fell to pieces. She screamed at me, she said, I'm not her sister. But there are always people who want to continue the harmonious life decorated with lies, such as the middle-aged woman called "mother". The 22nd birthday party turned into a farce, and the next day, everyone acted as if nothing had happened. But, I never saw "my" sister again. That's when I saw the "me" that no one else could see. "I" always stared at me fiercely through the window or something else, as if I was going to be cut into pieces at the next moment. Who is she? Who am I? It was necessary for me to find the answer to this question myself. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
