Watch the reunion of Park Solomon, Cho Yi Hyun, Han Sung Min, Yoo In soo, Lee Eun Saem in All of Our Dead! Though Cho Yi Hyun here was just a guest role in one ep
This is mind blowing! Okay Ba Reum is the real Han Seo Joon son. That’s why in ep.6 when han seo joon felt that Yo Han is not really the one he asked the prison doctor to confirm and when he found out that her ex wife did abandon their son he cursed her and not to mention Yo han was probably is the real son from the 2nd family of Ji Eun(mother). YH was seeking revenge for his father and sister that Han seo joon son kills that’s why he investigating Ba Reum this explains of photos of Ba Reum in the wall. And the other victims because he really wants to confirm if Ba Reum really did that. Also in ep. 6, YH asked his mother if she knew that her son is a murderer? (not referring to himself but referring to Han seo joon son). All the killings of the victim it turns out Ba Reum is always present. Even the scheme of fake video it was Ba Reum idea because he is plotting everything ahead of time. Maybe Bong Yi’s grandmother knows that Ba Reum is the killer, maybe when she trying to explain that YH is probably the killer YH appears and explained to grandmother that he is only investigating Ba Reum because he suspect him to be the murderer. Then YH run out and BR chases after him because he knows the truth. But I guess the reason why YH doesn’t speak out it’s because he wants more concrete evidence and personally want BR to be punished on his own hand. He also said that Killer is left handed to change the direction of investigation but Bong Yi state that killer is really right handed. Lastly, on the rooftop the confrontation between the unveils but BR knows that BY called for help that’s why he make himself as a victim. And he succeeded because YH was gunshot by Moo Chi, that’s why this explains the expression on his face when the first shot (fails) 2nd shot targeted him unfortunately. He is practically clueless of what happened. Then BR last word in the last minute of episode is ‘’Finally, it’s quiet”. Because he successfully framed YH as the real serial killer. That’s only my opinion hehe
