Had no one discovered that female doctors are also split in personality? At the beginning, after the male protagonist left her home, another old grandmother with a different personality appeared. They watched TV and communicated together. But when the police found the doctor's body, they said they were still trying their best to find the family. The doctor and her kindly communicated with her. They should also know that they have a split personality, so they should work hard to do research. Use another role to show that it may be a hidden foreshadowing. If the doctor performs by himself, you may not be able to see it if you don’t understand it at first. It was too obvious to expose, but in the end the police said that they couldn’t find her family. It really wouldn’t be because they couldn’t find her.
