I saw the raws and I can tell you that next chapter, there won’t still be an explanation but i think it will be explained during chapter 45,46,47(i think) cuz in the raws there are only 44 chapters. In that chapter, the black haired guy, i think finally lost it(his head) and asked the blond guy about those bloody hands and black room cuz his teacher (the one who allowed the black haired guy to go school) was killed in an accident and he saw in the window that there are traces of blood in the grass (outside their house and inside their house, in the stairs as if someone was pulling a bloody corpse inside the house) that accident happened after his teacher visited their house. And the teacher also saw those shadows (you know the thing in the mirror) and he freaked out and ran out the house, then BOOM, in the morning, he was dead.
And in the raws, the teacher also saw the shadow before in the mirror when he visited the blond haired guy with his family ( dunno if it is his parents or his relatives that was with him) but the teacher saw the blond haired guy talking to the smiling creepily shadow in the mirror and I think it was also in the black room.
And the one thing I’m really curious of is those bloody hands can only be seen by other people(the teacher) in the mirror but how are those hands able to kill a person(the way the victims are killed is like their body exploded like a bomb and only blood is seen after the killings). And when I say that the black haired guy saw those traces of blood outside and inside of the house, he only saw them in the windows(mirrors).
HOW????! GOD DAMN IT???!!!!!
I’m all excited about the story and all but GOD DAMN IT, I just want to know the whole truth about the fucking black room and those bloody hands
