My theory is that when jun was little he accidentally vanished yeons parents due to the impact he lost his memories years l8r he now lives with yeon and memories are slowly getting back to him when jun vanishs people I think the body's go in the darkroom where its yeons job to finish them off I think the hands are from the dismembered body's and that's yeons power he can control hand or somthn but together they can become mass murders but I think that's what yeon wants he's using jun's power for evil although jun doesn't realize until the body vanish
i think this story involves a devil and dont you think the one who kills yeon woos parents is jun? or jun have DID ? but really ,, i think jun killed yeon woos parents argh so messed up
