According to my understanding in the original, it is the same person. Chris's mother Sharon was a good friend of Yan, and she was not very old when she died. As for Chris, he is pretending to be absinthe (that is, Chris), and it is only two roles played by absinthe. In episode 345, Judy explained that she was surprised to find that Sharon and Chris had the same fingerprint, which was proved by the same person. But as for the father who killed Judy 20 years ago, Chris is really too young, so we don't know her real age now, it should be about 40 years old. She just looks like she is in her twenties. Is it because she learned to change her face Because Yoshiko once said that Sharon and Yoshiko both studied with the same person, and Sharon is better than her, so she can change her face without any makeup tools. It's in 245 Golden Apples, so I think it's the same person.
