Basically its like their desires (when they wanted to be alone the hands killed the parents so they could be) they can only control it if they are together, i feel like a black room is more of a concept then an actual thing like their trauma and hate for the world accumulates and the hands are created from that (the resentment and everything they hate from the world)
I feel like the explanation at the end was really rushed and inadequate so is anyone able to explain to me what the deal was the mirrors? Like do Yeon-woo and jun control the hands in the mirrors or is it their malice and they can’t stop it? I’m pretty confused, and does that make them both evil or mentally unstable? And it said there are many black rooms, so are those rooms created by malice or ? Idk
