I think the Giyoon comes from a line of shamans most of the time those are who can truly see ghost. And think maybe he had a friend at one point in time who came from the same background. I think that friend may have died young due to an accidental drowning or something. And maybe just maybe he blames Giyoon for forgetting him and this is his way of getting back at him
