What if the uke was actually the one who killed his own father (in his sleepwalk) and because his memory is hazy after walking up, he can’t recall killing him but recalls guwon there. The uke of course wouldn’t think he would/could kill his own father so points the blame to guwon. Guwon could have seen the father running towards the uke, to which guwon wouldn’t recognize him trying to help his son/stop his son but would only see him trying to “attack” and in hence he would have killed the father to stop him
Just a thought
I think it was more the uke’s distorted memory, the uke wouldn’t think he is capable of killing his own father and in logic sense guwon must have done it; to follow I think guwon may have knocked the uke out after he killed his father, if I recall too he recently stated he was knocked out and that was what cause the sleep walking but I think he’s always had the sleepwalking without realizing or he developed the sleepwalking after the world went to shit but that’s just my theory
PLEASE, JUST STOP THIS MADNESS
