I can't remember if it's the case here or even if we do know what exactly hapenned to him in the first place but it's really common in that sort of story that the real owner of the body ended himself. So in most case they are already long gone. Still sad but it make the MC less guilty when they found out.
There was an episode which actually did notion to that.
Tbh I don't like taking over someone's body story.
It always makes me sad for the original body owner. As New Doyoon keeps repeating that he isn't the original owner of this body it just hurts even more. I keep thinking what happened to the original Doyoon. It sucks that they even have the same name. One day the original owner Doyoon will be forgotten
