Coincidentally, at that time, Ji Xiaoyu always hugged Liu Siyan and called him "Brother". She even said that she was scared.
Mrs. Liu felt that her daughter's soul was living in that child's body. In the end, Mr. Liu could not bear to send her to an orphanage.
"Xiaoyu, are you willing to be Liu Siyu?" Liu Siyan asked her.
Ji Xiaoyu did not understand what he meant, but the Liu couple understood. He was suggesting that they let this child take the place of Liu Siyu in their lives.
"So, you're the real brother she's been looking for," Liu Siyan said.
Ji Lingchen did not manage to find out about these things. This explained why Liu Siyu had never disappeared and why his sister could not be found. This was what happened. After the real Liu Siyu passed away, the Liu family found his sister. However, it was strange. His whole family was looking for his sister, so why didn't they call the police? Ji Lingchen was puzzled.
