The eight-year-old brother said he was born again. He took me, a five-year-old who is road blind, by the hand and found a child picking up garbage in the suburbs. The child wanted to find a rag doll from the trash. My brother pointed to the doll hairpin on my head and said, she is a rag doll. From now on, she is yours. After saying this, my brother left without looking back. I waited and waited, waiting and waiting, from noon to sunset. My brother never came back. At this time, a strange sound suddenly sounded in the air. The female protagonist didn't know it yet, but the male protagonist had been reborn. In this life, he will only treat the heroine who died tragically in his previous life as his own sister and take good care of her.
