I also have the physical copies of Painter of the Night and it's a huge bummer that they censored it. It looks a little better than the online version since it's not stark white censoring, but still bad. I'm pretty sure a lot the older manhwa artists just didn't bother drawing the dick and weren't about to go back and redraw when it got and official translation. At least now it's less common and more artists are drawing out everything because they know it will be more popular internationally if uncensored.

My mind is boggled by the fact that the French and T-Chinese versions for this are uncensored, but not the English version. Crazy.
