That is a possible guess, the killer might be a time traveller whom the FL’s mum was surprised to see and then she fell into the river and drowned :X ML might also be killed because the killer knew that he can time travel and know too much XD Also thinking if there is a time loop like “Someday or One Day”?
why does the kid keep calling his parents by their name not mom or dad?
He did call his mother “mom” in some parts and called the doctor “Dad Zhou” then clarified he is not his dad…as for the dad, he will probably do in upcoming episodes? XD He probably called the mother name as being playful?
