I tried to search for this manhwa anywhere else and I found an artist that has a very VERY similar artstyle to this one. However... they don't mention anything about creating a manhwa or even being connected to one. What I think is, the people got a commission from said artist and just posed it as a cover for their fake manhwa. I truly wish it's just me overthinking it and the artist is actually working on something cool..
OH HELL NAW
