This is my theory: yeonwoo and his family have something to do with a mirror and this mirror has demons or some spirits and possessed the family members to kill people . Yeonwoo was possessed by one of the spirit thingies so that’s not actually yeonwoo but the mirror spirit. Correct me or add to this theory please ╮( ̄▽ ̄)╭
Yessss it’s about time
