I feel like the artist got lazy and is just trying to finish this series as soon as possible... I was really waiting for this scene "In the blink of an eye, the waiting room was suddenly filled up by the black smoke, and as if it was alive, it quickly enveloped Jin-Woo’s body. “Heok?!” Woo Jin-Cheol jumped up in fright and took several steps back in a hurry. As his brows shot up real high…. The black smoke had transformed into a set of jet-black armour on Jin-Woo." Chapter 233 Guess the artist just decided to ignore this... sad
