추공 (Chugong)
So from what I’m assuming, the voice at the end of the chapter has a few options, A. It’s the Japanese Hunter Association Leader, which I doubt, B. One of the American or Japanese hunters that are there to ask for help or to be scouted, or C. The father with the the endless sleep disease. The last ones kind of a stretch though, just thought it might be possible since he’s got his subplot, and Jin-Woo should’ve met him before, or at least recognize him as similar to his best bud.
