why do i think that the actual killer is the newsreporter hong joo? and that she probably was one of the step…
No,I don't think so.She was involved with a killer in the past whom I believe to be other than HH.I think there was another killer who was a copycat of HH,maybe it was the first time little Hong Joo saw her father killing someone.She feels responsibility for what happened to the victim,so I believe she is not a psycho. if she was Jae-Hoon step sister she must now be the same age as Oh Bong yi (19 yo).
I think Sung Yo Han is not the biological son of Sung Ji Eun and that maybe Jae Hoon is the prison doctor. I can t understand why he showed the bible verses about punishment to his first victim as KMC explained(an for an eye),I mean he is the anti-church killer and it doesn t make sense that he used it to justify his vengeance.
