@Lian Yes he looks like him. I noticed that but we don't have the full background to this story. I've come to believe that myeong came to the village to take revenge on her and not to escape the police and that he knows everything other than what he shows.
@Jam jam Yeah that's pretty unclear yet. What doesn't make sense is that how he is a person and a ghost child at the same time? Maybe a twin? Or a curse he left behind?
