I have a feeling that after the accident, the soul tht is inside Yooyoung isn't the "lord's" that it belongs to the person standing outside the door when the "lord" and Kwon were going at it, maybe the soul inside yooyoung belongs to another disciple that was with kwon at the time? Maybe the soul was haunting too Yooyoung's body and when the "Lord's" soul left the body, due to the accident, the other guy took over Yooyoung's body.
same sentiments, it's like the OG Shin Yooyoung was the reincarnation of that "Lord", and the current Shin Yooyoung is the guy outside who took over after the OG died
