No one noticed him even though both of them are wearing the same white coat?

Bc his face is blurred..

But his clothes and body shouldn't be blurred right? Did they change it in the manhwa and added him with the coat?
I've heard before that he was supposed to be naked in ch - 225 but they put robes on him in the manhwa. Is this the same thing?

Okay I just found out the actual reason (more like I got spoiled lmao)

Fourth wall is not only reason. It seems to be the interference from both secretive plotter and another constellation that no one can see pass it (their face or how similar their outfits are)
