[TOMT][COMIC/MANGA] Webcomic/manga about artist that forgets how to draw faces as he learns anatomy and people around him including himself start to turn into skeletons.

I remember it was in black and white and think i saw it on webtoons but haven’t been able to find it since. I also remember that he tried his hardest to remember his girlfriends face but eventually forgot it and as he kept forgetting everyone around him turned into skeletons until it was just him.
