i think it was really only talked about on kpsm2. i even remember denying it at first bc i hadn't noticed it either. when some anon pointed it out i was all "i know my oppar's face, his nose isn't any different!!" lol. but then i actually compared some videos and pictures where his profile could be seen clearly and the difference was very noticeable, the entire tip was just... gone. but i think it was worse around that time than it is now? so i actually have no idea what happened to it. anons speculated that he got injections but i just have no idea. maybe it's just what anon below said. it's not that important anyways, i just liked the pointyness.
