I wonder if the kid is an undead and he's hiding him to stop him from being killed by gu won, or he's died and he's hiding him so gu won doesnt think he's useless or not good at looking after kids per his "role" in the town, either way it could lead up to a big discovery moment where mc sees gu won's real role in the town and why ppl are so scared of him
