There's no way this man is actively dying, maybe entering into a swift hibernation until he recuperates, bcuz in the first chapter of this manhwa was already shown him gaining consciousness under a pile of rumble, he should have been death since the very beginning, a bullet is child's play compared to being crushed by the weight of a whole ass building. Also Sysiphus tricked twice Thanatos, if anything he is not dying, he's cheating death itself, and maybe his boulder to push eternally is his life which does not found end in a world that has turned and active hell (Tartarus).
With the sudden crash the story now has a justification for an amnesia arch, which would make sense taking in account the first chapter has nothing to do with the dynamic exposed in this whole season. Either way, the evil twink is behind that wheel, the evil twink is behind whatever happens to Mujin so he keeps working a year after he learned the truth.
And last but not least, the father needs to die like rn






I just see it and become feral, and all of the sudden I'm barking at a pixel, GAH
I will die happy if a could suffocate in the plush of his belly
