After the Real Daughter Was Bound to the Cancer System, the Whole Family Collapsed

I am bound to the sick travel system. It's worn by thousands of people who think it's a real daughter. Everyone loves the fake daughter who has been carefully cared for by the family for sixteen years. My three brothers were afraid that I would snatch something that belonged to the fake daughter, so they ridiculed me. My biological parents were afraid that my appearance would hurt the fake daughter, so they tried their best to make up for her. They never considered my feelings. They took my desire for love as a threat and jealousy. Later, I was dying. Later, my second brother discovered the diary I had hidden under my pillow. They collapsed.
