I wonder if the attached spirit is going to turn out to be Yejin's father? It didn't have its memories wiped; her father was a shaman who was working in the village the day of the tragedy, and Yejin is now about to confront Minchan after all this time. If her father is the spirit and remembers what happened back then, maybe we will get some more information on the sequence of events from that day? Everybody is still blaming Minchan for it, but it's really much more complex than that.
I'm also wondering if Gweonyeom is the Jeoseung Samsin, because only certain people are allowed to see his face? If Gweonyeom is the Samsin, and also 'the faceless man' from Jeongmin's memories, then that means the Samsin is the one working to put Minchan's soul back together. And maybe that's why they retired in the first place, b/c of what happened to Minchan's soul. I kinda thought maybe Jeongmin was part of Minchan's soul (and that was why he was frail, b/c he only had part of a soul), but Gweonyeom said all the other parts of Minchan's soul 'had disappeared from this world'. Hmm...
