I'm sure grim reaper 444 is Kim Joon (who is dead)
I kinda feel like he isnt? bc kim joon died april 20th or something and grim reaper is 444 ... time doesnt fit and at the beginning grim reaper was founding a body in the ocean and that body was missing; bc grim reaper would know who he was if it wasnt . its just a theory though what do you think?
