I kinda worried about how I think the story will end.
I had theory that because lee nok already in underworld once, he need to finish that, with either be dead, or erasing the connection with Jae shin, imo, maybe the ending will be like the queen will die, and lee nok also die, (after fierce battle with queen and the evil spirit) but somehow Jae Shin will help him come back to life, again but Lee nok will lost all his connection to Jae Shin, (he won't remember Jae Shin, and unable to see ghost again)
This is not spoiler, it's just my imagination,
I do hope they won't suffer again tho
